Abstract
BACKGROUND Daily usage of facial masks during coronavirus disease 2019 pandemic influenced on facial dermatoses. OBJECTIVE This study investigated the impact of mask-wearing habits on facial dermatoses. METHODS A nationwide, observational, questionnaire-based survey was conducted from July through August 2021, involving 20 hospitals in Korea. RESULTS Among 1,958 facial dermatoses, 75.9% of patients experienced aggravation or development of new-onset facial dermatoses after wearing masks. In aggravated or newly developed acne patients (543 out of 743), associated factors were healthcare provider, female gender, and a long duration of mask-wearing. Irritating symptoms, xerosis, and hyperpigmentation were more frequently observed in this group. Aggravated or newly developed rosacea patients (515 out of 660) were likely to be female, young, and have a long duration of mask-wearing per day. Seborrheic dermatitis patients who experienced aggravation or de novo development (132 out of 184) were younger, and they more frequently involved the chin and jaw in addition to the nasolabial folds and both cheeks. Contact dermatitis patients (132 out of 147) with aggravation or de novo development tended to be female, involve both cheeks, and complain of pruritus. Aggravated or newly developed atopic dermatitis patients (165 out of 224) were more likely to be female, and had a higher baseline investigator global assessment score before mask-wearing. CONCLUSION Clinical features and factors related to aggravation were different according to the types of facial dermatoses.

Abstract
BACKGROUND More than half of acne patients have truncal acne on their chest, back, and shoulders. However, since most studies on acne have focused on the face, data on clinical characteristics and proper management for truncal acne are insufficient. OBJECTIVE To establish a Korean Acne Rosacea Society (KARS) consensus for experts' perception and treatment patterns of truncal acne. METHODS We conducted two rounds of the Dephi technique to gather expert opinion and reach a consensus on truncal acne. The first round comprised 48 questionnaires focusing on various aspects such as epidemiology, clinical features, diagnosis, treatment, prognosis and more, while second rounds consisted of 26 questionnaires. RESULTS A total of 36 dermatologists (36/38 KARS members, 94.7%) completed this survey. In the first-round survey, consensus was reached on 20 out of the 48 questions (41.7%). In the second-round questionnaire, consensus was achieved on 9 of the 26 questions (34.6%). The most unresponsive lesion to truncal acne treatment was scars (atrophic/hypertrophic). The most commonly used treatments for each non-inflammatory and inflammatory truncal acne lesions were selected to use topical retinoids (78.1% of the responders) and oral antibiotics (93.8% of the responders). CONCLUSION Our study has yielded valuable insights into the epidemiology, clinical manifestations, diagnosis, treatment, and quality of life of patients with truncal acne. We anticipate that this study will inspire further comprehensive research for individuals with truncal acne.

Abstract
Chordoma is a rare locally aggressive bone malignancy that originates from the notochord. It typically involves the sacrococcygeal area, spheno-occipital region of the skull, and spine. Cutaneous involvement of chordoma, termed as chordoma cutis, is uncommon and usually occurs via direct invasion or local recurrence. Distant metastasis to the skin is very rare. We report a case of chordoma cutis on the scalp, which lacked characteristic physaliferous cells but tested positive for brachyury, thus supporting the diagnosis of chordoma cutis. The patient, who presented with a solitary translucent nodule on the scalp, was previously diagnosed with chordoma on the vertebral column and skull 8 months prior. Microscopic examination showed a cord-like arrangement of plasmacytoid cells within a myxoid stroma. Physaliferous cells were not observed, and cytokeratin AE1/AE3 staining was negative; however, brachyury and epithelial membrane antigen staining was positive, leading to the diagnosis of chordoma cutis. Therefore, clinicians must include chordoma cutis in the differential diagnosis of translucent nodular lesions on the skin of patients formerly diagnosed with chordoma.

Abstract
A 63-year-old male presented with a painful skin lesion on the left side of the neck and upper chest approximately two months prior to presentation. Diffuse erythematous to purplish-colored sclerotic patches were observed. He had been treated with intravenous antibiotics for two weeks for cellulitis, but the lesion did not improve. Punch biopsy, and neck computed tomography (CT) with contrast enhancement were performed to differentiate between cellulitis and scleroderma. Histopathological examination revealed infiltration of pleomorphic and poorly differentiated tumor cells extending into thickened collagen bundles, and mitotic activity. Based on histologic and radiologic findings, the patient was suspected to have poorly differentiated carcinoma, and further evaluation of the origin of the carcinoma was performed. A subareolar mass on the left breast was observed on chest CT, and a needle biopsy was performed; results were consistent with findings from the skin biopsy. Finally, the patient was diagnosed with carcinoma en cuirasse, a subtype of cutaneous metastasis of breast cancer, was transferred to oncology, and underwent palliative chemotherapy.

Abstract
Polydeoxyribonucleotide (PDRN) is a mixture of deoxyribonucleotides. It serves as an anti‑inflammatory and tissue‑regenerating agent. The mitogen‑activated protein kinase pathway modulates cell growth and collagen accumulation. It also regulates inflammation by suppressing the expression of proinflammatory cytokines. In the present study, it was attempted to elucidate the molecular mechanism of PDRN in skin healing by confirming the effects of PDRN treatment on skin keratinocytes and fibroblasts, and by assessing the levels of collagen and inflammatory cytokines regulated by the extracellular signal‑regulated kinase (ERK) pathway. The potential effects of PDRN on skin regeneration were investigated. Fibroblast and keratinocyte proliferation and migration were analyzed using the water‑soluble tetrazolium‑8 and wound healing assays. The upregulation of collagen synthesis by PDRN‑induced ERK activation was analyzed in fibroblasts with or without an ERK inhibitor. Inflammatory cytokine expression levels in keratinocytes were determined using reverse transcription‑quantitative polymerase chain reaction. PDRN promoted the proliferation and migration of keratinocytes and fibroblasts. However, PDRN‑induced ERK phosphorylation differed between keratinocytes and fibroblasts; PDRN increased ERK phosphorylation and collagen accumulation in fibroblasts, while it inhibited matrix metalloproteinase expression. By contrast, PDRN inhibited ERK phosphorylation in keratinocytes, and it decreased inflammatory cytokine expression levels. PDRN affects skin cell proliferation and migration, and collagen and inflammatory cytokine expression levels via ERK signaling. Overall, PDRN exerts a positive effect on skin regeneration, but the mechanism by which it promotes skin regeneration varies among different skin cell types.

Abstract
OBJECTIVES North Korean Refugees (NKRs) undergo defection, and this has been shown to impact their current health status in South Korea. However, little is understood about how the defection process is related to metabolic syndrome (MetS). This study regarded the defection process to be a quasi-measurement of traumatic experience and investigated whether defection was a risk factor for MetS among NKRs living in South Korea. STUDY DESIGN This cross-sectional study obtained data from the Korea University Anam Hospital in Seoul. NKRs (N = 847) voluntarily completed questionnaires and underwent at least one medical examination between October 2008 and July 2021. METHODS Multivariable logistic regression models were used to evaluate whether the number of countries transited by NKRs was associated with MetS by controlling for covariates. RESULTS The prevalence of MetS among male and female NKRs in South Korea was 12.3% and 13.3%, respectively. The highest prevalence of MetS (33.4%) was among NKRs who had transited two countries. The number of months in transit countries (mean: 49.9 ± 51.7) and period of residence in South Korea (mean: 40.9 ± 40.9 months) were also considered. NKRs who transited three countries had a higher probability of MetS (odds ratio [OR] 2.660, 95% confidence interval [CI] 1.161-6.097) than those who travelled directly to South Korea. NKRs who transited three countries and had only resided in South Korea for a short period had a higher probability of MetS (OR 3.424, 95% CI 1.149-10.208) than those who have lived in South Korea for a longer period. CONCLUSIONS Considering the social vulnerability of NKRs and consequential health problems, there is an urgent need for appropriate support from the government and society.

Abstract
A 75-year-old male was diagnosed with idiopathic pulmonary fibrosis and treated with pirfenidone. He presented with an erythematous thick scaly patch on his face, neck, and both hands and arms. He had a history of significant exposure to sunlight without using sunscreen. All lesions were restricted to sun-exposed areas and appeared one month ago. Histopathological examination revealed necrotic keratinocytes, epidermal spongiosis, liquefaction degeneration of the basal layer, interface dermatitis, solar elastosis, and upper dermal perivascular lympho-histiocytic infiltration. Based on clinical and histopathological findings, the skin lesion could be diagnosed as photosensitive drug eruption induced by pirfenidone. Pirfenidone was discontinued for a month, and the patient was treated with oral and topical corticosteroids. Consequently, the skin lesion almost fully cleared, leaving mild postinflammatory hyperpigmentation. Although there are many reports of photosensitivity reactions to pirfenidone, dermatologists are still not familiar with this drug. Through this case presentation, clinicians should be aware of the potential phototoxic effects of pirfenidone and provide the necessary precautionary information to patients who take pirfenidone.

Abstract
Hajdu-Cheney syndrome (HCS) is an inherited skeletal disorder caused by mutations in the Notch homolog protein 2 gene (NOTCH2). Treatment of this rare disease is challenging because there are no established guidelines worldwide. Previous case reports using bisphosphonates, denosumab, or teriparatide suggested that curative treatment for HCS did not exist yet in terms of preventing the disease progression. Therefore, the efficacy of romosozumab for osteoporosis in patients with HCS needs to be evaluated. Herein, we report the case of a 43-year-old woman who had progressive acro-osteolysis and repeated fractures since the age of 29 years. Next-generation sequencing confirmed HCS with a mutation at nucleotide 6758G>A, leading to Trp2253Ter replacement in NOTCH2. Romosozumab treatment was initiated because she had already received bisphosphonate for more than 10 years at other hospitals. After 1 year of romosozumab treatment, the bone mineral density (BMD) increased by 10.2%, 6.3%, and 1.3%, with Z scores of -2.9, -1.6, and -1.2 at the lumbar spine, femoral neck, and total hip, respectively. In addition, C-telopeptide was suppressed by 26.4% (0.121 to 0.089 ng/mL), and procollagen type I N-terminal propeptide increased by 18.7% (25.2 to 29.9 ng/mL). This was the first report of romosozumab treatment in patient with osteoporosis and HCS in Korea. One year of romosozumab treatment provided substantial gains in BMD with maintaining the last acro-osteolytic status without deteriorating, representing a possible treatment option for HCS.

Abstract
BACKGROUND Sensitive skin is a subjective cutaneous hyper-reactivity that occurs in response to various innocuous stimuli. Keratinocytes have recently been shown to participate in sensory transduction by releasing many neuroactive molecules that bind to intra-epidermal free nerve endings and modulate nociception. In the literature, the characterization of these interactions has been based on the co-culture of keratinocyte and mammalian-origin neuronal cell lines. In this study, we established an in vitro model based on a co-culture of primary human keratinocytes and differentiated SH-SY5Y cells, a human neuronal cell line. METHODS Human epidermal keratinocytes and SH-SY5Y cells were monocultured and co-cultured. Changes in calcium influx, substance P, inflammatory cytokines, and neuropeptides between the monoculture and co-culture groups treated with capsaicin only and capsaicin with transient receptor potential channel vanilloid subfamily member 1 (TRPV1) antagonist, trans-4-tert-butylcyclohexanol (TTBC), together. In addition, the difference in stinging sensation was evaluated by applying it to the volunteers. RESULTS When SH-SY5Y cells were co-cultured with keratinocytes, they had no significant effect on axonal development. Substance P was also released after capsaicin treatment and reduced by TTBC under co-culture conditions. Moreover, the expression of inflammatory cytokines and neuropeptides was significantly increased in co-cultured keratinocytes compared to that under monoculture conditions. In addition, the stinging sensation was significantly induced after the application of capsaicin in vivo and was relieved after the application of the TRPV1 antagonist. CONCLUSION We demonstrated that the novel co-culture model is functionally valid through capsaicin and TRPV1 antagonist. We also confirmed that TTBC could be used for the treatment of sensitive skin through a co-culture model and in vivo tests. This co-culture model of keratinocytes and SH-SY5Y cells may be useful in vitro alternatives for studying the close communication between keratinocytes and neuronal cells and for screening therapeutic drugs for sensitive skin.

Abstract
BACKGROUND Psoriasis imposes a significant treatment burden on patients, particularly impacting well-being and quality of life (QoL). The psychosocial impact of psoriasis treatments remains unexplored in most patient populations. OBJECTIVE To assess the impact of adalimumab on health-related QoL (HRQoL) in Korean patients with psoriasis. METHODS This 24-week, multicenter, observational study, assessed HRQoL in Korean patients treated with adalimumab in a real-world setting. Patient-reported outcomes (PROs) including European Quality of Life-5 Dimension scale (EQ-5D), EQ-5D VAS, SF-36, and DLQI were evaluated at week 16 and 24, versus baseline. Patient satisfaction was assessed using TSQM. RESULTS Among 97 enrolled patients, 77 were assessed for treatment effectiveness. Most patients were male (52, 67.5%) and mean age was 45.4 years. Median baseline body surface area and Psoriasis Area and Severity Index (PASI) scores were 15.00 (range 4.00~80.00) and 12.40 (range 2.70~39.40), respectively. Statistically significant improvements in all PROs were observed between baseline and week 24. Mean EQ-5D score improved from 0.88 (standard deviation [SD], 0.14) at baseline to 0.91 (SD, 0.17) at week 24 (p=0.0067). The number of patients with changes in PASI 75, 90, or 100 from baseline to week 16 and 24 were 65 (84.4%), 17 (22.1%), and 1 (1.3%); and 64 (83.1%), 21 (27.3%), and 2 (2.6%), respectively. Overall treatment satisfaction was reported, including effectiveness and convenience. No unexpected safety findings were noted. CONCLUSION Adalimumab improved QoL and was well-tolerated in Korean patients with moderate to severe psoriasis, as demonstrated in a real-world setting. Clinical trial registration number (clinicaltrials.gov: NCT03099083).

Abstract
Herpes zoster is caused by the varicella-zoster virus, which becomes latent in ganglia after primary infection. When the varicella-zoster virus reactivates on the cranial nerve, the patient can suffer from cranial nerve palsy, pain, and skin lesions on the head and neck area. A 57-year-old immunocompetent male presented with dysphagia lasting 10 days. Computed tomography and other neurological findings were normal. However, laryngoscopy showed right vocal cord paralysis, which might be the reason for dysphagia in this patient. There was a grouped crusted lesion on the right posterior auricular area that appeared 5 days after the dysphagia. After famciclovir and prednisolone combination therapy, the patient was cured with no sequelae. This is a rare case of herpes zoster in an immunocompetent patient who presented with dysphagia. In addition, it was difficult to make an accurate diagnosis because his skin lesion appeared several days after dysphagia.

Abstract
BACKGROUND Omalizumab is a very important drug for the treatment of chronic urticaria. Although omalizumab's therapeutic efficacy has been demonstrated, data on real-world experiences in Korea, especially regarding chronic inducible urticaria (CIndU), are limited. This study attempted to compare the efficacy of omalizumab in Korean chronic spontaneous urticaria (CSU) and CIndU patients. METHODS Fifty-two CSU and 29 CIndU patients were included and Urticaria Activity Score 7 (UAS7) at baseline, week 4, and week 12 was assessed retrospectively. RESULTS Omalizumab 150 mg significantly decreased UAS7 in both patients with CSU and CIndU with only one dose (P < 0.001). The significant decrease in the UAS7 scores of both groups of patients continued from weeks 4 to 12. Although there was no significant difference in treatment efficacy between the two groups, the symptoms of patients with CSU tended to improve faster; furthermore, the number of antihistamines administered daily reduced more significantly in this patient group (P = 0.047). Additionally, the decrease in the UAS7 score between baseline and week 12 and the response rate were higher in patients with CSU. CONCLUSION Omalizumab may be slightly more effective against CSU than against CIndU. Regarding the CIndU subtypes, dermatographic urticaria was associated with the greatest reduction in the UAS7 score, and patients with this condition showed the highest response rate, indicating the best effect of omalizumab. The duration of chronic urticaria was greater in non-responders than in responders (P = 0.025). Conversely, baseline immunoglobulin E levels were significantly higher in responders (P = 0.039).

Abstract
Background Some alopecic diseases can be diagnosed by detailed history taking and physical examination, but in many cases, biopsy must be performed to make a definite diagnosis. Aims and Objectives This study aimed to evaluate the clinico-pathological concordance of scalp lesions showing alopecia. Materials and Methods We retrospectively reviewed the electronic medical records and biopsy slides of patients who underwent biopsy for evaluating scalp lesions showing alopecia. Based on the definitions of clinico-pathological concordances, scalp alopecic disease was evaluated. Results A total of 121 patients were enrolled in the study. A total of 203 clinical differential diagnoses were made before performing a biopsy. Thirty-one patients showed full concordance, and 58 patients showed partial concordance; thus overall concordance was shown in 89 patients (73.55%). Folliculitis decalvans and alopecia areata showed a higher full concordance rate than average (P < 0.05), whereas dissecting folliculitis showed a lower overall concordance rate than average, and folliculitis decalvans showed a higher overall concordance rate than average (P < 0.05). The overall concordance rate of alopecia areata was 100% (P = 0.061). Conclusion In diagnosing folliculitis decalvans and alopecia areata, which showed high full and overall concordance, performing a biopsy to make a definite diagnosis is not always necessary, especially when patients show typical clinical features. Dissecting folliculitis, which showed low overall concordance, was less likely to be suspected as a clinical differential diagnosis, making it difficult to distinguish based on clinical findings alone. Therefore, when it is suspected, a detailed evaluation including a biopsy is recommended.

Abstract
Friction melanosis (FM) is an acquired pigmented disease that is caused by recurrent mechanical stress. There is no previous report explaining the presence of tiny brown-colored particles confined to the corneal layer. We describe a case of a rare form of FM of the finger that showed a relatively transient clinical course. A 17-year-old Korean female presented with a 5-month history of an asymptomatic localized hyperpigmented patch on the tip of the right index finger. The dermoscopic examination revealed homogenous globular pattern, which favored pigmentation over hemorrhage. Histopathologically, hyperkeratosis and acanthosis with lymphohistiocytic infiltration of the superficial dermis were noted on hematoxylin and eosin staining; however, there was neither a definite increase in melanophages in the upper dermis nor melanocytic proliferation in the basal layer. Per high-power field, multiple brown-colored tiny particles were scattered in the corneal layer. The particles were not dyed by Fontana-Masson stain, iron stain, and S-100. We questioned the patient about the presence of irritation and found that she had bought new shoes at the time of the onset. She was habituated to placing her fingers in her shoes while wearing them because they were slightly tight. The lesion disappeared spontaneously a week after the cause of friction was eliminated. Altogether, we encountered a rare form of FM that occurred in a rare location with a transient clinical course. Further cases on pigmentation restricted to finger tips might reveal the origin of the particles.

Abstract
Background: Granulomatous rosacea is a distinct variant of rosacea because of its unique histopatholiogic findings. However, the pathogenesis of granulomatous rosacea has not yet been clearly demonstrated. Aims and Objectives: The aim of this study was to investigate the expression of toll-like receptor 2, mast cells, and neurofilaments in the granulomatous rosacea compared with the non-granulomatous rosacea. Materials and Methods: Biopsy specimens were obtained from 12 patients with erythematotelangiectatic rosacea, 11 patients with granulomatous rosacea, and 11 control patients. Biopsy tissue blocks were subjected to immunohistochemical staining using antibodies against toll-like receptor 2, mast cells, and neurofilaments. Results: In granulomatous rosacea, the expression of mast cells increased significantly, compared to the erythematotelangiectatic rosacea and the control group (P-value = 0.001 and 0.013, respectively). Additionally, the expression of toll-like receptor 2 in the granulomatous rosacea group was higher than that in the control group (P-value = 0.04). Conclusion: The results of this study suggest that the increased expression of mast cells may be a sign of chronic, later stage of granulomatous rosacea compared to the erythematotelangiectatic rosacea. The increased expression of toll-like receptor 2 suggests that cathelicidin-induced neuroimmune pathogenesis also contributes to the pathophysiology of granulomatous rosacea.

Abstract
A description of the upgraded bunch-by-bunch feedback system for time-resolved experiments at Pohang Light Source II (PLS-II) is provided. The bunch-by-bunch feedback system has been upgraded to increase the single-bunch current in the hybrid fill pattern of the PLS-II facility. The project is part of the SPring-8 and PLS-II collaboration. The main features of the upgrade are to employ a single 500 MHz analog-to-digital converter (ADC) instead of the previous four 125 MHz interleaved ADCs for 500 MHz rate, to replace a single-loop two-dimensional feedback with two independent one-dimensional feedback loops, to implement the tune measurement function with a single bunch, and mainly to implement single-bunch and stretcher control. The realization of a 400 mA hybrid fill pattern including a 10 mA single bunch demonstrates the precision of the upgraded bunch-by-bunch feedback system.

Abstract
A 10-year-old boy presented with a 1-day history of multiple painful erythematous skin lesions on his upper and lower extremities. He was admitted to the Department of Pediatrics with persistent right lower abdominal pain and diarrhea. Punch biopsy of a skin lesion on his lower leg showed necrotizing granulomatous vasculitis with septal panniculitis consistent with polyarteritis nodosa, and our differential diagnosis included cutaneous manifestations of Croh's disease. Abdominal ultrasonography revealed distended colonic loops suggestive of inflammatory bowel disease. Upper and lower gastrointestinal endoscopy revealed lesions involving the duodenum, cecum, colon, and rectum. He developed multiple perianal fistulas during hospitalization. Additional laboratory tests revealed positive results for anti-saccharomyces cerevisiae and antinuclear antibodies. Based on his clinical presentation and laboratory findings, he was diagnosed with Crohn's disease associated with cutaneous polyarteritis nodosa. We report a rare case of a child who presented with cutaneous polyarteritis nodosa as an extraintestinal manifestation of Crohn's disease.

Abstract
Wolf's isotopic response refers to the occurrence of a novel skin disease at the site of a preceding treated or untreated skin disease. Although the most common preceding skin disease was found to be herpes zoster (HZ), HZ-related dermatological phenomena are not well known in the literature. We report a case of HZ granulomatous dermatitis in a 77-year-old female with a previous history of hypertension, diabetes mellitus, chronic kidney disease, and HZ. She presented with a 3-month history of a pruritic skin lesion on her right thigh. The location of the lesion was consistent with a previous HZ site. Histopathological examination revealed lympho- histiocytic infiltration in the superficial dermis, forming a granulomatous structure. Based on clinical and histopathological findings, we made a diagnosis of granulomatous dermatitis at a previous HZ site. We assumed that the lesion arose from an isotopic response of Wolf. The patient was treated with topical steroids for 3 months and showed clearance of the lesion and symptom. We suggest that treatment should be based on the individual disease, which in our case was topical steroid.

Abstract
A 70-year-old female was referred for brown-to-gray colored papules and nodules on her lower legs. She had been diagnosed with diffuse large B-cell lymphoma (DLBCL) in her stomach, and myelodysplastic syndrome (MDS) by bone marrow biopsy. Three years after complete remission of DLBCL, she experienced DLBCL recurrence in her small bowel and was hospitalized. MDS had been stationary, but during the treatment of DLBCL, her laboratory findings suggested signs of leukemia. Bone marrow biopsy was done, and acute monoblastic leukemia (AMoL) was diagnosed. After 1 cycle of chemotherapy for AMoL, skin lesions developed, and her skin biopsy showed cutaneous T-cell lymphoma (CTCL). Terminal deoxynucleotidyl transferase staining and CD123 staining were negative, and bone marrow re-biopsy conducted after the skin lesion developed still showed monoblastic proliferation. Whether the CTCL represented with an AMoL lineage switch could not be completely proved due to the absence of molecular or clonal marker evaluations, but the possibility of coexistence of three different malignancies was higher. During treatment, a neutropenic fever developed, and the patient died due to sepsis. We herein report a rare case of CTCL accompanied by AmoL and DLBCL.

Abstract
Postmarketing surveillance is conducted to establish drug safety and effectiveness under real-world practice. We aimed to validate the effectiveness and safety of ustekinumab in the treatment of adult Korean patients with plaque psoriasis under real-world practice. This was a prospective, observational, and multi-center study. Subjects aged 18 years or older who were treated with ustekinumab for plaque psoriasis were enrolled. We enrolled 977 patients; 654 (66.9%) were men, with mean body surface area (BSA, ± standard deviation) of 27.0 ± 18.3% and mean psoriasis area severity index (PASI) score of 18.1 ± 9.7. The effectiveness analysis was performed in 581 patients who had at least one follow-up assessment and met treatment criteria per local label and reimbursement guidelines. Of these patients, 287 had effectiveness data for visit 6 at 53.7 ± 2.1 weeks. At visit 6, 91.6% (263/287), 51.2% (147/287), and 9.4% (27/287) patients achieved PASI 75, 90, and 100 responses, respectively. Adverse events (AEs) occurred in 112 of the 977 (11.5%) patients with an incidence rate of 21.5 per 100 patient-years (PYs). Serious AEs occurred in eight (0.8%) patients with an incidence rate of 1.2 per 100 PYs. The estimated 1-year drug survival rate was 87.7%. The multiple logistic regression analysis showed that higher baseline PASI score and no prior biologic exposure were significant predictors for PASI 90 response at visit 6. Ustekinumab was effective and safe, and displayed a high survival rate in the treatment of adult Korean patients with plaque psoriasis in real-world practice.

Abstract
BACKGROUND The concept of frailty has been suggested to comprise physical, mental, and social phenotypes. However, there is no general consensus about the appropriate components for assessing frailty. OBJECTIVES The purpose of this study was to reach consensus on components of frailty assessment using the Delphi process. METHODS To achieve consensus on the definition of frailty, a modified Delphi method was used. Geriatric and gerontologic experts were selected from various fields. The detailed components of frailty were composed of data from the Korean Frailty and Aging Cohort Study. Establishing consensus and collecting opinions from experts were conducted using a modified Delphi method. RESULTS Overall, nine domains with 14 components of frailty assessment were accepted. There was consensus on the necessity of a broad phenotype including physical, mental, and social frailty. CONCLUSIONS Consensus on the components of a frailty assessment in a clinical setting is achieved through the Delphi process to establish a new tool of frailty assessment.

Abstract
AIM The main aim of this study was to compare the long-term outcome of a conventional colorectal endoscopic submucosal dissection (ESD) in which submucosal dissection was continued throughout until the completion of resection (ESD-T) to hybrid endoscopic submucosal dissection (ESD-H) in the colorectum. METHOD Medical records of 836 colorectal neoplasia patients treated by ESD-T or ESD-H were reviewed. ESD-H was defined as colorectal ESD with additional snaring in the final stage of the procedure. Primary outcomes were the overall and metastatic recurrence rates. Secondary outcomes were short-term outcomes such as the en bloc resection rate, procedure time and adverse events. RESULTS The overall recurrence rate was higher in the ESD-H than in the ESD-T group (5.7% vs 0.7%, P = 0.001). The metastatic recurrence rate showed no significant difference between these groups (1.4% vs 1.4%, P = 1.000). Multivariate analysis revealed that a failed en bloc resection (hazard ratio 24.097; 95% CI 5.446-106.237; P < 0.001) and larger tumour size (hazard ratio 1.042; 95% CI 1.014-1.070; P = 0.003) were independently associated with overall recurrence. The ESD-H group showed a lower en bloc resection rate (56.8% vs 96.5%, P < 0.001), shorter procedure time (45.6 vs 54.3 min, P < 0.001) and higher perforation rate (10.3% vs 6.0%, P = 0.029). CONCLUSION Although long-term outcomes in terms of overall recurrence are inferior following ESD-H, a failed en bloc resection and large tumour size are the only independent risk factors for recurrence. Further investigations are warranted to improve the long-term outcomes of ESD-H.

Abstract
A 62-year-old female, with previous history of asthma and hypertension, presented with generalized hyperpigmented skin lesion, found a year ago. Physical examination revealed brown colored lichenified and sclerotic patches on the lower abdomen and flexural areas of extremities. Punch biopsy was performed and histopathological examination revealed hyperkeratosis, follicular plugging and thinning in epidermis. In dermoepidermal junction, cleft like space separating atrophic epidermis and dermis was seen. Also, lichenoid lymphocytic infiltration was observed in mid-dermis. Based on clinical and histopathological findings, a diagnosis of generlaized lichen sclerosus et atrophicus (LSA) was made. Other laboratory examinations were unremarkable. As there is no standard treatment for LSA, the patient received various treatments including topical steroid, tacrolimus and narrow-band ultraviolet B therapy. The skin lesion has softened and its color improved after treatment. LSA is defined as infrequent chronic inflammatory dermatosis with anogenital and extragenital manifestations. Generalized type is rare and genital involvement is the most frequent and often the only site of involvement. We report this case as it is an uncommon type of LSA with generalized hyperpigmented and sclerotic skin lesion in a postmenopausal female patient.

Abstract
Solitary fibrous tumor (SFT) is a relatively uncommon mesenchymal neoplasm that usually arises in the pleura, but also has been reported in numerous extrapleural locations, including cutaneous site. The skin lesion presents as a circumscribed nodule or tumor, mainly on the head and neck. A 41-year-old male presented with 6 months history of nail lesion without symptom on the left third finger. The lesion is slightly yellowish discoloration with subungual erythematous nodule and distal onycholysis. Biopsy specimen from the nail lesion showed the spindle cells form patternless pattern with hypercellular and hypocellular area. And small blood vessels and dilated vascular spaces were present. The result of special stain for specimen showed that positive for CD34, Bcl-2, and CD99 but negative for S-100, FactorXIIIa, and smooth muscle action. Recognition of this uncommon location of SFT is important because of possible confusion with other subungual tumors, including glomus tumor, fibroma and other fibrohistiocytic tumors like dermatofibrosarcoma protuberans, superficial acral fibromyxoma and cellular digital fibroma. Here in, we report a case of SFT of subungual region. We think this case is interesting because of uncommon location and may be helpful to more understand the character of this disease.

Abstract
BACKGROUND Germline mutations in BRCA1 and BRCA2 (BRCA1/2) have been conventionally analyzed by Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA). Nowadays, next-generation sequencing (NGS) is increasingly being used in clinical genetics. The aim of this study was to evaluate the performance of NGS BRCA1/2 assays by comparing them with the conventional method. MATERIALS AND METHODS We did BRCA1/2 NGS assays of 108 breast and/or ovarian cancer patients whose BRCA1/2 mutation had been previously analyzed by Sanger sequencing and MLPA using TruSeq Custom Amplicon Design AFP2. Single-nucleotide variations (SNVs) and small insertions or deletions (InDels) were evaluated. In addition, we analyzed large genomic rearrangements (LGRs) using a coverage-based algorithm as well as a revised BRCA1/2 NGS assay (BRCAaccuTest PLUS), which additionally covered a BRCA1 promoter region. RESULTS The NGS BRCA1/2 assay detected all 20 SNVs and 21 small InDels in 56 patients. Among seven LGRs detected by MLPA, six exonic LGRs were well identified by both NGS BRCA1/2 assays. One pathogenic LGR, located on a BRCA1 promoter region, was successfully identified using revised BRCAaccuTestPLUS. CONCLUSIONS These results indicated that an NGS BRCA1/2 assay could detect most LGRs including BRCA1 promoter-region deletion as well as SNVs and small InDels. Therefore, it was applicable to clinical BRCA1/2 mutation tests.

Abstract
Patients presenting with green nail syndrome often show coinfection with fungus. A delay in the accurate diagnosis of coinfection may warrant longer treatment duration. Four patients with green nail syndrome coinfected with fungus were reviewed retrospectively. Fungal culture, cultivating Candida parapsilosis and Candida albicans, was performed in two patients' samples. The mean time of the initiation of treatment for onychomycosis after the first visit was 5.75 weeks. If green nail syndrome is suspected, screening for fungal coinfections and precise management are necessary.

Abstract
29 Background: Hematological malignancies are forms of cancer that originates in blood-forming tissue, such as bone marrow, or in the cells of the immune system. Detection of genetic alteration in hematological malignancies are increasingly important because of diverse variants associated with classification and diagnosis of subtypes, and prognostic and therapeutic-response prediction. Next-generation sequencing (NGS) is a powerful technology to simultaneously analyze multiple genes to identify clinically well-described variants, as well as rare variants related to hematological malignancies for clinical diagnostics. Methods: We developed the targeted NGS panel (HEMEaccuTest) and automatic analysis software (NGeneAnalySys) for estimating pathogenicity of genetic variants related to hematological malignancies. HEMEaccuTest covers entire coding region of 108 genes that have putatively known for associations with the diseases according to the WHO, NCCN and ELN guidelines. The diagnostic utility of HEMEaccuTest and NGeneAnalySys were validated using reference materials and clinical specimens. Results: The results showed that pathogenic variants were effectively detected with an average coverage depth of 600X and a minimum coverage depth of 100X. It demonstrated an excellent limit of detection, with 100% sensitivity for SNVs at 2% VAF and for indel at 4% VAF. In addition, the analytical sensitivity, specificity and precision of the panel were higher compared to conventional methods such as Sanger sequencing, FISH, and real-time PCR. Noticeably, the approximately 300-bp-size insertions of FLT3-ITD was efficiently detected by a simulating algorithm. Conclusions: This analytical validation study demonstrated that HEMEaccuTest and NGeneAnalySys can be an excellent and useful tool for disease definition and therapeutic strategy in hematological malignancies. NGeneAnalySys provides the evidence-based categorization and clinical interpretation supported by Tier classification (Therapeutic, Prognostic, Diagnostic) of professional guidelines (ACMG/AMP, AMP/ASCO/CAP. etc).

Abstract
Hypertrophic scar is a dermal fibroproliferative disease characterized by the overproduction and deposition of extracellular matrix, and the hyperproliferation and enhanced angiogenesis of fibroblasts, along with their enhanced differentiation to myofibroblasts. Botulinum toxin type A shows potential for prevention of hypertrophic scar formation; however, its effectiveness in attenuating skin fibrosis and the related mechanism are unclear. In this study, human scar fibroblasts were cultured and stimulated with botulinum toxin type A, and the changes in fibroblast proliferation, migration, and protein expression of pro-fibrotic factors were evaluated with colorimetric, scratch, and enzyme-linked immunosorbent assays and western blotting, respectively. Botulinum toxin type A treatment decreased the proliferation and migration of human scar fibroblasts compared with those of untreated controls. Protein expression levels of pro-fibrotic factors (transforming growth factor β1, interleukin-6, and connective tissue growth factor) were also inhibited by botulinum toxin type A, whereas the JNK phosphorylation level was increased. Activation of the JNK pathway demonstrated the inhibitory effects of the toxin on human scar fibroblast proliferation and production of pro-fibrotic factors, suggesting that the suppressive effects of botulinum toxin type A are closely associated with JNK phosphorylation. Overall, this study showed that botulinum toxin type A has a suppressive effect on extracellular matrix production and scar-related factors in human scar fibroblasts in vitro, and that regulation of JNK signaling plays an important role in this process. Our results provide a theoretical basis, at the cellular level, for the therapeutic use of botulinum toxin type A.

Abstract
Distinguishing between Malassezia folliculitis (Pityrosporum folliculitis [P. folliculitis]) and acneiform eruption, based on clinicopathological features, is challenging for clinicians. In the literature, the histopathological differences between P. folliculitis and acneiform eruption lesions have been poorly described. We aimed to determine the clinicopathologic distinctions between P. folliculitis and acneiform eruption by retrospectively analyzing the histology of hematoxylin and eosin stained tissue sections obtained from 52 patients diagnosed with these lesions. The presence of fungal spores in the follicular lumen was most consistent with a P. folliculitis diagnosis (P < 0.001). However, intrafollicular inflammation (P = 0.009), irregular patterns of keratin plugging (P = 0.008), and nuclear dust in the follicular lumen (P < 0.001) favored an acneiform eruption diagnosis. These intrafollicular characteristics and inflammatory differences are believed to be caused by necrotic keratinocytes that lead to vacuolar changes in the follicular wall (P = 0.013). We did not observe any difference between P. folliculitis and acneiform eruption lesions in terms of perifollicular inflammatory cell infiltration. Our study demonstrated that significant differences exist between P. folliculitis and acneiform eruption lesions relative to the presence of necrotic keratinocytes in the follicular wall, intrafollicular characteristics, and inflammatory cell infiltrations. Necrotic keratinocytes are believed to have a key role in these differences. These findings may contribute to an improved understanding of the pathogenesis and differential diagnosis of P. folliculitis and acneiform eruption.

Abstract
e14606 Background: Hematological malignancies are forms of cancer that originate in blood-forming tissue, such as bone marrow, or in the cells of the immune system. Hematological malignancies can be classified as leukemias, lymphomas, multiple myeloma (MM), myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN) based on the cell type where they originate. Detection of genetic alteration in hematological malignancies is increasingly important because of diverse variants associated with classification and diagnosis of subtypes, and prognostic and therapeutic-response prediction. Next-generation sequencing (NGS) is an advanced technology to simultaneously analyze multiple genes to identify clinically well-described variants, as well as rare variants related for clinical diagnostics. Methods: We developed the targeted NGS panel, HEMEaccuTest and automatic analysis software, NGeneAnalySys for estimating the relative pathogenicity of hematological malignancies. HEMEaccuTest covers about the 310 kilobases with exon regions of 108 genes that have putatively known for associations with the diseases according to the WHO, NCCN and ELN guidelines. the diagnostic utility of the panel and software were validated using genotype-known reference materials and clinical specimens. Results: The results showed that pathogenic variants were effectively detected with an average coverage depth of 600x and a minimum coverage depth of 100x.

Abstract
Patients with atopic dermatitis have high rates of skin surface colonization of Staphylococcus aureus. At the same time, S. aureus is the major causative organism in infective endocarditis, approximately accounting for 30%~50% cases of infective endocarditis. A 22-year-old male with severe atopic dermatitis presented with fever and myalgia. He was diagnosed with active infective endocarditis causing multiple cerebral infarction, splenic infarction, and septic shoulder requiring synovectomy. Blood culture proved methicillinsensitive Staphylococcus aureus bacteremia, and the culture from the skin revealed same bacteria. After treated with intravenous antibiotics for 6 weeks, patient was improved. Another 42-year-old female with severe atopic dermatitis who presented with fever and chilling was hospitalized due to acute infective endocarditis. She also had left flank pain and visual disturbance, due to splenic infarction and acute cerebral infarction, respectively. As blood culture revealed methicillin-sensitive Staphylococcus aureus bacteremia, she treated with intravenous antibiotics for 6 weeks. The route of entry of two patients was attributed to the patient eczematous scratching lesion of poorly controlled atopic dermatitis. Infective endocarditis can result in the context of acute deterioration of atopic dermatitis. Dermatologists need to pay attention to this risk and actively manage such conditions in order to decrease the risk of infective endocarditis arising from skin lesions in atopic patients. For these reasons, we herein report two cases of infective endocarditis in patients with atopic dermatitis.

Abstract
BACKGROUND AND AIM The associations of long-term exposure to particulate matter <10 μm in size (PM10), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3) with cardiometabolic diseases (CMD) remain uncertain in the Korean population. Therefore, we sought to examine the associations between PM10, NO2, CO, SO2, and O3 and CMD using data collected from the Korean Community Health Survey. METHODS AND RESULTS We selected 100,867 adults aged 19 years or older who had lived in the same domicile for ≥10 years and surveyed them to collect data on socioeconomic characteristics; health-related behaviors; obesity; and physician-diagnosed CMD history, including hypertension, diabetes mellitus, dyslipidemia, stroke, myocardial infarction, and ischemic heart disease. We calculated interquartile ranges for PM10, NO2, CO, SO2, and O3 from the 10 year average concentrations (2003-2012). Hypertension, diabetes mellitus, and dyslipidemia were positively associated with PM10, NO2, CO, SO2, and O3 after adjusting for confounding factors. Obesity was positively associated with PM10, NO2, SO2, and O3. On the other hand, we found no associations between stroke, myocardial infarction, and ischemic heart disease and exposure to PM10, NO2, CO, SO2, and O3 in these subjects. In subjects aged ≥65 years, the risk of dyslipidemia was markedly increased under exposure to NO2 and CO compared to subjects aged <65 years. The risk of obesity was also significantly increased under exposure to PM10 and NO2. However, sex differences in these associations were not found. CONCLUSION Long-term exposure to PM10, NO2, CO, SO2, and O3 may be a risk factor of CMD in Korean adults.

Abstract
Background Psoriasis and psoriatic arthritis (PsA) are included in the group of immune-mediated inflammatory diseases (IMIDs) caused by systemic inflammation; however, indicators for monitoring inflammatory activity in patients with psoriasis, such as the Psoriasis Area and Severity Index (PASI), are limited. Objective To determine whether the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire can be used to monitor disease activity in patients with psoriasis. Methods This was a multicenter, noninterventional, cross-sectional study. Demographic factors and PASI and PASE scores were collected to investigate associations between each. Results PASE data were available for 1,255 patients, of whom 498 (39.7%) had a score of ≥37. Compared with the group with PASE score <37, the group with score ≥37 had a higher proportion of women (34.9% vs. 48.8%, p<0.0001), older mean age at diagnosis (36.4 vs. 41.7 years, p<0.0001), more severe disease activity using PASI and body surface area measures (p=0.0021 and p=0.0008, respectively), and higher mean body mass index (23.7 vs. 24.1, p=0.0411). In a multiple linear regression model, PASE score was positively associated with cutaneous disease activity (p<0.0001). Conclusion After risk-adjustment, PASE was positively associated with PASI, which suggests that PASE can be sensitive to disease activity. Since psoriasis is regarded as one of the IMIDs, PASE may be utilized as a tool not only to screen PsA but also to monitor disease activity.

Abstract
Background Recently, the number of domestic pets has increased. As a consequence, sensitization to animal allergens, such as cat or dog allergens, has become a problem. Objective We studied the annual trends of sensitization to cats or dogs, and the characteristics of the patients. Methods We retrospectively analyzed the medical records of 7,469 patients who visited a dermatology clinic and underwent an allergic profile test, from January 2011 to December 2015. Specific immunoglobulin E (IgE) levels to cat or dog antibody greater than 3.50 IU/ml were regarded as positive results. Results In all, 274 patients showed significant increase in levels of specific IgE antibody to dog, and 307 revealed increase in levels of of specific IgE antibody to cat. The prevalence of these specific IgEs increased from 2011 to 2015. Independent risks for sensitization to cat allergens were sensitization to dog, but not to house dust, Dermatophagoides pteronyssinus, and D. farinae. Independent risks for sensitization to dog allergens were sensitization to cat, but not to house dust, D. pteronyssinus, and D. farinae. Total IgE level was not related to specific IgE level against either cats or dogs. Conclusion In conclusion, the prevalence of sensitization to cat or dog has increased. Sensitization to cat or dog is related to each other, but is irrelevant to the total IgE level.

Abstract
Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disorder. Although several epidemiological studies have been conducted in Western countries, such data regarding Asian populations are scarce. In this study, we sought to investigate the demographic and clinical features of HS in Korea. A total of 438 patients, diagnosed with HS from May 2007 to April 2017, were enrolled and the electronic medical record of each patient was reviewed. Male patients were predominant with a male : female ratio of 2.5:1. Mean age of disease onset was 23.9 years and most patients had no family history. The most frequently affected area was the buttocks, followed by axillae and groin. Acne and diabetes mellitus were the most prevalent associated diseases and no patients with inflammatory bowel diseases were observed. In the univariable analysis, male patients had severe diseases compared with females with an odds ratio (OR) of 1.790. Two or more affected body regions were associated with HS severity with an OR of 1.693. While involvement of the perineum (OR, 4.067) and buttocks (OR, 1.471) tended to be associated with increased severity of the disease, the inguinal area (OR, 0.620) showed a tendency to be inversely associated with the severity. In multivariable analysis, identified risk factors were the involvement of the perineum (OR, 3.819) and buttocks (OR, 2.288). Smoking status and high body mass index seemed to be associated with more severe diseases. Our results will provide clinical characteristics of HS patients in Asia and help to broaden understanding of HS.

Abstract
BACKGROUND Platelet-rich plasma (PRP) is a blood fraction that contains high concentrations of several growth factors. PRP has been recently used in skin wound healing and rejuvenation. However, the precise molecular mechanisms underlying PRP-induced wound healing are unknown. AIMS This study aimed to evaluate the effects of PRP on extracellular matrix remodeling, which requires the activation of dermal fibroblasts. METHODS Cell proliferation and migration assay, enzyme-linked immunosorbent analysis, and Western blotting were performed on PRP-treated human skin fibroblasts. RESULTS Platelet numbers were enhanced by 4.6-fold in PRP compared to that in whole blood. PRP stimulated the proliferation and migration of human dermal fibroblasts and increased the expression of human procollagen I alpha 1, elastin, MMP-1, and MMP-2 in human dermal fibroblasts. PRP-treated human dermal fibroblasts also showed a dramatic reduction in the phosphorylation of c-Jun N-terminal kinase (JNK), whereas total JNK levels were not significantly reduced. CONCLUSIONS Collectively, PRP induced increased expression of type I collagen, elastin, MMP-1, and MMP-2, thereby accelerating wound healing. Our findings reveal basic mechanisms underlying PRP-mediated tissue remodeling. Thus, these results could be exploited for clinical dermatology and skin rejuvenation.

Abstract
Rosacea is a common chronic inflammatory skin condition. Although several epidemiological and etiologic studies with large sample sizes have been conducted on Caucasians, such data regarding Asian populations are lacking. A total of 580 patients diagnosed with rosacea were enrolled from October 2014 to February 2015 at 14 general hospitals. Questionnaires, including the standard classification and grading system, were used for evaluation. The average age of the patients was 47.9 years. While 83.8% of patients revealed a single subtype, 16.2% of patients revealed mixed subtypes showing two or more subtypes simultaneously. Erythematotelangiectatic rosacea (ETR) was the most prevalent subtype. ETR combined with papulopustular rosacea showed the highest proportion in the mixed subtype group. Mild severity was revealed in 71.9% of patients. The most common aggravating factor was emotional changes (51.7%), followed by stress (48.4%). Approximately half of the patients (47.4%) showed relatively low awareness of rosacea. By identifying the epidemiological and etiologic features in Korea, we can suggest valuable clinical avenues for research, education and awareness among rosacea patients.

Abstract
Background: Diphenylcyclopropenone (DPCP) immunotherapy for viral warts has been used for many years, but no studies have analyzed the treatment effects of DPCP alone, without the use of conventional therapy before immunotherapy. Objectives: We evaluated clinical efficacy of DPCP monotherapy compared to cryotherapy and pulsed dye laser (PDL) therapy. We also assessed the impact of initial sensitization on clinical response. Methods: We retrospectively analyzed the medical records of 250 patients with multiple viral warts between January 2008 and December 2015. Results: The DPCP-only group (n = 43) showed a lower clinical response (75.6%) than the cryotherapy-only group (n = 171, 89.8%, P < .01) and PDL-only group (n = 36, 90.3%, P < .01). The positive clinical response was 76.3% (119/156) in the successful sensitization group (n = 21) and 74.4% in the failed sensitization group ( P = .870). Conclusions: DPCP monotherapy has a lower clinical response than conventional therapy. Initial sensitization to DPCP does not predict a failed response with continued immunotherapy for viral warts.

Abstract
BACKGROUND Psychological aspect and quality of life should be considered in treating patients with psoriasis. OBJECTIVE We sought to ascertain which clinical characteristics including presence of exposed lesions are associated with impairment of health-related quality of life (HRQoL) in patients with psoriasis. METHODS The EPI-PSODE study was a nationwide, multicenter, cross-sectional study conducted in Korea that included 1260 adult patients with psoriasis. In addition to clinical characteristics including presence of exposed lesions, data were collected using the Psoriatic Arthritis (PsA) Screening and Evaluation (PASE), Dermatology Life Quality Index (DLQI), MOS 36-Item Short-Form Health Survey (SF-36), Work Productivity and Activity Impairment Questionnaire Psoriasis (WPAI: PSO) and Medication Satisfaction Questionnaire (MSQ). RESULTS Patients with a DLQI score > 5 (n = 990) were younger, had an earlier onset of psoriasis, scored higher on the Psoriasis Area and Severity Index (PASI), had higher body surface area (BSA) and had higher PASE scores than patients with DLQI ≤ 5 (n = 266). The group of patients with exposed lesions (n = 871) were younger and male predominance, earlier onset of psoriasis, longer disease duration, higher PASI/BSA score and a higher proportion with drinking and smoking history each than the group of patients without exposed lesions (n = 389). Presence of exposed lesions negatively influenced DLQI, 36-Item Short-Form Health Survey (SF-36) (mental component), presenteeism, total work productivity impairment and total activity impairment in the WPAI: PSO. In multiple regression model, PASI score was the only variable which was significantly associated with all HRQoL measures. Presence of exposed lesions was a significant factor affecting DLQI and SF-36 (mental). CONCLUSION The presence of exposed lesions has a negative impact on quality of life, mental health and work productivity. Therefore, effective treatments are particularly needed for psoriasis patients with exposed lesions.

Abstract
Background Rosacea is a chronic inflammatory disease characterized by centrofacial erythema. Excess cathelicidin is suggested to be important to the pathophysiology of the disease. Recently, presence of a vitamin D response element was revealed in the cathelicidin gene promoter. Objective The aim of this study was to determine whether vitamin D and cathelicidin are associated with rosacea, both serologically and histopathologically. Methods Subjects with rosacea and without chronic skin disorders were enrolled in the patient and control groups, respectively. Serum 25-hydroxy-vitamin D and cathelicidin levels were measured. Tissue expression of cathelicidin and vitamin D receptor were measured with immunostaining-intensity-distribution index. Results The mean serum 25-hydroxyvitamin D level of patients with rosacea was 12.18±5.65 ng/ml, which is lower than that of the controls (17.41±6.75 ng/ml). Mean serum cathelicidin levels in patients with rosacea and the controls were 85.0±26.1 ng/ml and 55.0±23.3 ng/ml, respectively. Cathelicidin expression in rosacea tissue was significantly higher than that in control tissue (5.21 vs. 4.03). No significant difference was observed in vitamin D receptor expression. Conclusion Higher cathelicidin expression in rosacea supports the hypothesis that an abnormal inflammatory response of the innate immune system is important in pathogenesis of rosacea, but the role of high cathelicidin serum levels is complicated. Serum vitamin D was lower in patients with rosacea, although serum cathelicidin was higher than that of the controls. This suggests that the role of vitamin D level in the pathogenesis of rosacea merits further investigation.

Abstract
BACKGROUND Rosacea is characterized by erythema on face, especially erythema and linear telangiectasia on the nose. Currently, various vascular lasers are used for treatment, and among them, are long-pulsed Nd:YAG(LPNY) and pulsed dye laser (PDL). OBJECTIVES This study compared the efficacy of LPNY and PDL in treating rosacea-associated nasal telangiectasia. METHODS Patients with rosacea who showed erythema and telangiectasia on the nose were included. Each patient was treated with PDL on the left side of the nasal bridge, and LPNY on the right side, three times with 4-week intervals. At the end of the treatment, two independent dermatologists evaluated overall treatment response compared with baseline. RESULTS The physician's assessment of treatment concluded that good improvement was seen in six PDL and seven LPNY patients, and excellent improvement five PDL and four LPNY patients. There was no significant difference (p = 0.62, 95%CI) between the groups. Overall improvement was similar; however, LPNY induced a greater response in thick, dilated vessels, while erythema with mild telangiectasia was more responsive to PDL. CONCLUSION Both LPNY and PDL are effective in treating rosacea-associated nasal telangiectasia. If LPNY is used properly to avoid side effects with careful consideration, it can also be used as a good modality.

Abstract
A 4-month-old infant presented with asymptomatic soft nodules on his right forearm, which had developed since birth. On the suspicion of nevus lipomatosus superficialis (NLS), biopsy was performed. Histopathologic findings showed monomorphic polygonal cells with abundant granular cytoplasm. Immunohistochemical stains for CD68 and vimentin were strongly positive, but were negative for S-100 protein. Based on the pathologic findings, the patient was diagnosed as non-neural granular cell tumor (NN-GCT). GCT can be divided into conventional and non-neural GCT by immunoreactivity for S-100 protein. NN-GCT is typically manifested as a well-circumscribed, papulo-nodular dermal mass, and is known to occur in a younger group than does in conventional GCT, but is rare among children. To our knowledge, there have been no case reports of NN-GCT which appeared at birth and presented as grouped nodules. Therefore, we report this interesting case of congenital NN-GCT clinically mimicking NLS.
