Abstract
BACKGROUND/AIM Immune checkpoint inhibitors (ICI) and tumor-infiltrating lymphocytes (TILs) for cancer treatment in clinical oncology have revolutionized patient care. However, no gold standard exists for the criteria of analytical validity of TILs of different types of cancer. MATERIALS AND METHODS Clinicopathological data from 60 patients with endometrioid carcinoma (EC) who had undergone surgical treatment at the Gyeongsang National University Hospital between January 2002 and December 2009, were investigated. The programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PDL1) expression levels were characterized by immunohistochemical staining patterns, and the interpretations derived from machine learning morphometric analysis (Genie) and the pathologists' assessments were compared. In solid tumors, pathologists assessed the proportion of positive cells in each core of the tissue microarray. For Genie, the proportion of positive cells in the entire core and the number of positive cells per 1 mm2 were used. RESULTS Both the pathologists and Genie identified the same trend in association with tumor size, with significant differences (p=0.026, p=0.033). Genie expression showed a significant association with PD1 expression, and pathologists identified a significant association with PDL1 expression in immune cells. CONCLUSION The PD1 expression levels identified in immune cells of EC specimens were similar between the pathologists and Genie, suggesting that there is little resistance to the introduction of morphometric analysis. To our knowledge, this is the first study to introduce and validate machine learning as an integrated method for predicting prognosis and treatment based on PD1 expression in EC tumor microenvironments.

Abstract
Perilipin (PLIN) is a major structural protein located on the surface of lipid droplets. PLIN plays an important role in human metabolism and is associated with metabolic diseases, such as obesity, diabetes, hypertension, and endocrine disorders. The dysregulation of lipid metabolism is one of the most prominent metabolic changes observed in cancers. Therefore, the PLIN protein family has recently attracted attention owing to its role in lipid metabolism and cancer. To date, no studies have addressed the association between the prognosis of lung cancer and PLIN1 expression. For the first time, we found that high PLIN1 expression was significantly correlated with worse disease-free survival (DFS) in lung squamous cell carcinoma (SCC). We examined PLIN1 expression by the immunohistochemical analysis of surgical lung SCC specimens obtained from 94 patients. We analyzed the correlation between PLIN1 expression, clinicopathological data, and patient survival, using a chi-squared test, Kaplan-Meier analysis with log-rank tests, and the multivariate Cox proportional hazards regression test. High PLIN1 expression was significantly correlated with lower DFS in the Kaplan-Meier analysis and the multivariate Cox proportional hazards regression model. High PLIN1 expression was significantly correlated with worse prognosis in lung SCC.

Abstract
BACKGROUND Kikuchi-Fujimoto disease (KFD) is a rare, self-limiting inflammatory condition of unknown etiology that is characterized by fever and painful lymphadenopathy. KFD commonly involves the posterior cervical region and very rarely occurs in the axilla. CASE PRESENTATION We report on a case of KFD that presented 3 weeks after receiving the messenger ribonucleic acid-based coronavirus disease 2019 (COVID-19) vaccine. In this case, we suspected the lesions as COVID-19 vaccination-related lymphadenopathy on the initial ultrasonographic examination. CONCLUSION Through this case report, we highlight that KFD should be considered in the differential diagnosis of patients with axillary lymphadenopathy who have undergone COVID-19 vaccination, as unusual side effects of COVID-19 vaccination have been increasingly reported in the literature owing to the rapid development of various COVID-19 vaccines during the pandemic period. In addition, we emphasize the importance of clinical suspicion in diagnosing KFD due to the fact that axillary involvement of KFD is extremely rare.

Abstract
RATIONALE Only 1 case of IgA nephropathy (IgAN) with minimal change disease (MCD) associated with primary Sjögren's syndrome (SS) has been reported. We additionally describe IgAN with MCD associated with primary SS. PATIENT CONCERNS A 80-year-old woman visited our hospital complaining of generalized edema that had started 4 weeks prior. She reported a sense of thirst and dry eye for the last 5 years. DIAGNOSES Her initial laboratory findings were compatible with nephrotic syndrome; both the antinuclear antibody (1:80) and anti-SS-A (Ro) antibody (200 U/mL) tests were positive. A salivary gland scan revealed markedly decreased uptake for both the parotid and submandibular glands. The Schirmer test was positive. The random urine protein/creatinine ratio was 10 mg/mg. Renal biopsy was compatible with IgAN with superimposed MCD. INTERVENTIONS Furosemide was intravenously administered with intermittent albumin infusion for her edema control. She was started on prednisone 40mg daily for 6 weeks, which was tapered to 5 mg for another 6 months after starting prednisolone. OUTCOMES Over the next 6 months, her edema improved and the proteinuria decreased significantly. LESSONS Physician should suspect IgA with MCD when patient with SS clinically showed nephrotic syndrome, and perform renal biopsy for pathologically diagnosis and appropriate treatment.

Abstract
BACKGROUND/AIM As maternal morbidity and mortality during pregnancy have increased during the COVID-19 pandemic, studies on pregnancy-related complications from SARS-CoV-2 infection are being actively conducted. Considering that pregnant women with COVID-19 may develop a preeclampsia (PE)-like syndrome, it is necessary to differentiate it from PE because true PE can result in an unfavorable perinatal outcome during a hasty delivery. MATERIALS AND METHODS We investigated the protein expression of transmembrane serine protease 2 (TMPRSS2) and angiotensin-converting enzyme 2 (ACE2) in placental samples from 42 normotensive (n=9) and PE (n=33) patients without SARS-CoV-2 infection. We isolated placental trophoblast cells from normotensive and PE patients without evidence of SARS-CoV-2 infection to determine the mRNA and protein expression levels of TMPRSS2 and ACE2. RESULTS High ACE2 cytoplasmic expression in extravillous trophoblasts (EVTs) was correlated with lower fibrin deposition (p=0.017). In comparison with high nuclear TMPRSS2 expression, low nuclearTMPRSS2 expression in endothelial cells (ECs) was positively correlated with PE (p=0.005), significantly higher systolic blood pressure (p=0.006), and higher urine protein-to-creatinine ratio (p=0.022). In contrast, high cytoplasmic TMPRSS2 expression in fibroblasts (FBs) was correlated with higher urine protein-to-creatinine ratio (p=0.018). Trophoblast cells extracted from PE placental tissue showed lower mRNA levels for both ACE2 and TMPRSS2. CONCLUSION TMPRSS2 nuclear expression in ECs and cytoplasmic expression in FBs of the placenta may be related to a trophoblast-independent PE mechanism, and TMPRSS2 could be a new biomarker to discriminate actual PE from a PE-like syndrome associated with COVID-19.

Abstract
BACKGROUND/AIM RAB27A and RAB27B are involved in exosome secretion. To date, there have been many attempts to elucidate the roles of RAB27A and RAB27B in the prognosis of various cancer types. The association of RAB27A and RAB27B expression with the clinical and pathological features was evaluated in patients with stomach cancer. MATERIALS AND METHODS A total of 360 patients who had undergone surgery for stomach cancer between January 1999 and December 2007 at Gyeongsang National University were enrolled in the study. Disease-free survival (DFS) and disease-specific survival (DSS) were compared according to immunohistochemistry of tumor samples. RAB27A and RAB27B mRNA and protein were also extracted from four stomach cancer cell lines using quantitative polymerase chain reaction and western blotting. RESULTS Strong nuclear RAB27A expression in tumor samples was statistically significantly correlated with lymph node metastasis. Cytoplasmic RAB27B expression was related to poor disease-free survival and its combined cytoplasmic and membranous expression was related to disease-specific survival of patients with different histopathological types of stomach cancer. High RAB27A expression and high RAB27B expression was found in four stomach cancer cell blocks. Among the four cell lines, NCI-N87 exhibited the lowest relative mRNA density and HS746T exhibited the highest relative protein density for both RAB27A and RAB27B. CONCLUSION RAB27A and RAB27B expression may help predict lymph node metastasis and survival of patients with gastric cancer.

Abstract
We aimed to quantitatively analyze the exosome and its cargo in individual aqueous humor (AH) samples from pseudoexfoliation (PEX) glaucoma patients compared to controls using a novel detection platform. We investigated the size distribution and measured the quantitative exosome particle counts in each AH sample. AH (80–120 µL) was obtained during cataract surgery or glaucoma filtering surgery from 12 Korean subjects (six with PEX glaucoma and six age-matched controls). The mean size of the exosomes was 58.9 ± 18.5 nm measured by a tangential flow filtration system using single-particle interferometric reflectance imaging sensor. Exosome particle count in each CD 63, CD 81, and CD9 spot was significantly greater in PEX glaucoma than in controls in total, CD 63, CD9, syntenin, and scattering(all p < 0.003). The CD63 spot showed a particle count of 8319.1 ± 797.7 in PEX glaucoma patients and 4786.8 ± 1302.1 in controls (p = 1.88E−11). Individual fluorescent capture spot images also revealed denser exosome particles in PEX patients than in controls. Syntenin, indicating exosomal origin, was detected in all AH samples. Exosomes differentially detected in AH suggest the possible role of exosomes in the pathogenesis of PEX glaucoma.

Abstract
Background Myoferlin is a multifunctional protein expressed in various normal and cancer cells, with novel oncogenic roles being newly discovered. Recently, correlations have been found between myoferlin expression and unfavorable prognosis in various carcinomas. This study investigated the prognostic role of myoferlin expression in papillary thyroid carcinoma (PTC), specifically that associated with nodal metastasis. Methods We collected clinicopathological data and PTC tissues from 116 patients who had been admitted to Gyeongsang National University Hospital in 2010. Immunohistochemical analysis was performed on surgical specimen-derived tissue microarray blocks. Myoferlin expression was graded, and the relationship between expression level and pathological features of tumors based on the American Joint Committee on Cancer staging system was evaluated. Results Of the 116 patient samples, 100 cases exhibited positive myoferlin expression. Higher grade of myoferlin expression was correlated with lower T category group (p = .010). Presence of lymph node metastasis was determined to be significantly correlated with low-grade myoferlin expression (p = .019), with no significant difference between pN1a and pN1b tumors. Conclusions Our study revealed an adverse correlation between myoferlin expression and pathological features of PTC, evidence of the potential prognostic role of myoferlin in PTC lymph node metastasis.

Abstract
Objective: To investigate the diagnostic potential of Fc fragment of IgG receptor 1b gene (FCGR1B) transcription level in active tuberculosis. Methods: From February to September of 2018, we collected peripheral blood from patients with active tuberculosis, latent tuberculosis infection (LTBI), cured patients with tuberculosis, healthy people and patients with pneumonia in the Eighth Medical Center of PLA General Hospital. Peripheral blood mononuclear cells (PBMCs) were isolated for total RNA extraction and cDNA synthesis. The expression of FCGR1B mRNA in PBMCs was detected by quantitative real-time PCR (QPCR). Nonparametric test was used to compare the differential expression of FCGR1B mRNA between patients with active tuberculosis and control groups, and the relationships between FCGR1B mRNA expression and patient's illness condition and inflammatory indexes were analyzed by Correlation analysis. The potential of FCGR1B mRNA as a diagnostic marker for active tuberculosis was evaluated by receiver operating characteristic curve (ROC) analysis. Results: The expression of FCGR1B mRNA in PBMCs from patients with active tuberculosis was significantly increased when compared with non-tuberculosis controls, including individuals with LTBI, healthy people, cured patients with tuberculosis and patients with pneumonia (u=2 081, P<0.001). The expression of FCGR1B mRNA was higher in patients with tuberculosis who had more bacteria(H=12.35, P=0.015), and was correlated with the C-reactive protein (CRP) (r=0.30, P=0.008). ROC analysis showed that FCGR1B mRNA could distinguish active tuberculosis from non-tuberculosis with area under curve (AUC) of 0.849. The sensitivity and specificity were 71.43% and 84.17% respectively. The AUC of FCGR1B mRNA in distinguishing extra-pulmonary tuberculosis from controls was 0.906. The sensitivity and specificity were 84.62% and 91.89%, respectively. Conclusion: FCGR1B mRNA is a potential molecular marker for diagnosis of active tuberculosis.

Abstract
BACKGROUND Diffusion-weighted imaging plays a key role in magnetic resonance imaging (MRI) of breast tumors. However, it remains unclear how to interpret single diffusion encoding with respect to its link with tissue microstructure. The purpose of this retrospective cross-sectional study was to use tensor-valued diffusion encoding to investigate the underlying microstructure of invasive ductal carcinoma (IDC) and evaluate its potential value in a clinical setting. METHODS We retrospectively reviewed biopsy-proven breast cancer patients who underwent preoperative breast MRI examination from July 2020 to March 2021. We reviewed the MRI of 29 patients with 30 IDCs, including analysis by diffusional variance decomposition enabled by tensor-valued diffusion encoding. The diffusion parameters of mean diffusivity (MD), total mean kurtosis (MKT), anisotropic mean kurtosis (MKA), isotropic mean kurtosis (MKI), macroscopic fractional anisotropy (FA), and microscopic fractional anisotropy (µFA) were estimated. The parameter differences were compared between IDC and normal fibroglandular breast tissue (FGBT), as well as the association between the diffusion parameters and histopathologic items. RESULTS The mean value of MD in IDCs was significantly lower than that of normal FGBT (1.07±0.27 vs. 1.34±0.29, P<0.001); however, MKT, MKA, MKI, FA, and µFA were significantly higher (P<0.005). Among all the diffusion parameters, MKI was positively correlated with the tumor size on both MRI and pathological specimen (rs=0.38, P<0.05 vs. rs=0.54, P<0.01), whereas MKT had a positive correlation with the tumor size in the pathological specimen only (rs=0.47, P<0.02). In addition, the lymph node (LN) metastasis group had significantly higher MKT, MKA, and µFA compared to the metastasis negative group (P<0.05). CONCLUSIONS Tensor-valued diffusion encoding enables a useful non-invasive method for characterizing breast cancers with information on tissue microstructures. Particularly, µFA could be a potential imaging biomarker for evaluating breast cancers prior to surgery or chemotherapy.

Abstract
BACKGROUND/AIM The majority of patients with early-stage endometrial cancer (EC) have a good prognosis, but recurrence does occur despite diagnosis at an early stage. There is a growing need for early diagnosis of EC and novel treatment options. MATERIALS AND METHODS Human epidermal growth factor receptor 2 (HER2) and vascular endothelial growth factor receptor 2 (VEGFR) expression in microarrays of patient EC tissue was examined in association with clinicopathological data. HER2 and VEGFR2 expression in Ishikawa cells and differences in migration and proliferation of cells with HER2-knockdown were evaluated. RESULTS Higher expression of VEGFR2 was associated with lower International Federation of Obstetrics and Gynecology grades (p=0.044). The positive correlation between HER2 and VEFR2 expression was statistically significant in T1 stage (p=0.002) and International Federation of Obstetrics and Gynecology grade 1 tumors (p=0.004). Wound-healing assays revealed that HER2 loss in Ishikawa cells reduced confluence compared to that of control cells. CONCLUSION The association of VEGFR2 and HER2 expression in early EC was elucidated. This study shows that the measurement of VEGFR2 expression may be useful in the preoperative assessment of EC and suggests the possibility of anti-HER2 therapy for EC.

Abstract
BACKGROUND Sinonasal cavernous hemangioma is rare. To date, fewer than 20 cases have been reported in the world literature; however, they may be a source of recurrent epistaxis and masquerade a hemorrhagic mass on CT and MRI. CASE REPORT A 68-year-old woman presented with recurrent epistaxis and progressive right malar fullness. CT and MRI demonstrated a well-defined mass in the right maxillary sinus with T2 hyperintensity, and hypointense septa and peripheral rim, and multiple papillary enhancement which suggested a recurrent hemorrhagic mass suggested at rhinoscopy. The mass was excised endoscopically, and the histologic diagnosis was cavernous hemangioma. CONCLUSION Imaging studies, such as CT and MRI, are essential in making an accurate diagnosis of cavernous hemangioma of the maxillary sinus. Endoscopic excision of the lesion can be curative.

Abstract
Identifying the lung carcinoma subtype in small biopsy specimens is an important part of determining a suitable treatment plan but is often challenging without the help of special and/or immunohistochemical stains. Pathology image analysis that tackles this issue would be helpful for diagnoses and subtyping of lung carcinoma. In this study, we developed AI models to classify multinomial patterns of lung carcinoma; ADC, LCNEC, SCC, SCLC, and non-neoplastic lung tissue based on convolutional neural networks (CNN or ConvNet). Four CNNs that were pre-trained using transfer learning and one CNN built from scratch were used to classify patch images from pathology whole-slide images (WSIs). We first evaluated the diagnostic performance of each model in the test sets. The Xception model and the CNN built from scratch both achieved the highest performance with a macro average AUC of 0.90. The CNN built from scratch model obtained a macro average AUC of 0.97 on the dataset of four classes excluding LCNEC, and 0.95 on the dataset of three subtypes of lung carcinomas; NSCLC, SCLC, and non-tumor, respectively. Of particular note is that the relatively simple CNN built from scratch may be an approach for pathological image analysis.

Abstract
BACKGROUND/AIM Programmed death ligand-1 (PD-L1) and programmed death protein 1 (PD-1) expression levels in many tumors and their correlation with prognosis have been actively studied. However, studies on PD-1 expression and its prognostic value in clear cell renal cell carcinoma (ccRCC) are limited and controversial. In this study, we describe the expression of PD-1 and its prognostic significance and association with clinical features in patients with ccRCC. MATERIALS AND METHODS We obtained clinicopathological data from 166 patients with ccRCC who were treated at Gyeongsang National University Hospital, Jinju, Korea between January 2000 and December 2009. Tissue microarray blocks were made using representative paraffin blocks of ccRCC specimens. Two pathologists analyzed PD-L1 and PD-1 expression in both tumor and inflammatory cells. RESULTS PD-1 expression in tumor-infiltrating inflammatory cells was significantly correlated with unfavorable disease-free survival (DFS) (p<0.001) and disease-specific survival (DSS) (p=0.002) in the univariate analysis. A statistically significant correlation between PD-1 expression and unfavorable DFS (p=0.025) was observed in the multivariate analysis. CONCLUSION PD-1 expression in tumor-infiltrating inflammatory cells serves as an independent prognostic factor for unfavorable DSS in patients with ccRCC.

Abstract
BACKGROUND/AIM Core needle biopsy (CNB) has been widely used as an alternative method to ultrasound-guided fine-needle aspiration cytology for histological diagnosis of thyroid specimens. However, nuclear artifactual vacuoles (NuVas) produced during tissue processing can be very difficult and sometimes impossible to distinguish from intranuclear inclusions (NuIns). P62 is an autophagy receptor that recognizes, targets, and eliminates toxic cellular materials during autophagy. Herein, we examined the utility of p62 immunohistochemical staining to detect NuIns in thyroid core needle biopsy specimens. PATIENTS AND METHODS Thirty-five thyroid CNB slides from 32 patients and corresponding resection specimens stained with hematoxylin and eosin were reviewed by two pathologists. The immunohistochemical staining pattern of p62 was used to differentiate NuIns from NuVas. The diameter of each nucleus (A) and NuIn (B) was measured, and the number of p62-expressing NuIn-positive (p62In) cells was counted using 1/2 (B/A) and 1/3 (B/A) criteria. The criterion of 1/3 includes NuIns larger than 1/3 and smaller than 1/2 of the nuclear diameter. The criteria of 1/2 includes NuIns larger than 1/2 of the nuclear diameter. RESULTS By applying the 1/2 criterion, there were no p62In cells in follicular adenoma (FA) samples. However, in papillary thyroid carcinoma (PTC) samples, 22 of 25 specimens exhibited p62In cells. The sensitivity and specificity to distinguish FA from PTC using the 1/2 criterion were 0.88 and 1.00, respectively. By applying the 1/3 criterion, there was one p62In cell hit in FA samples. However, 23 of 25 PTC specimens showed p62In cells. The sensitivity and specificity to distinguish FA from PTC using the 1/3 criterion were 1.00 and 0.90, respectively. CONCLUSION P62 is a useful marker for distinguishing FA and PTC based on CNB specimens. We suggest the 1/2 criteria for identifying p62In cells.

Abstract
Background Smoking‐ and nonsmoking‐associated lung cancers have different mechanisms of carcinogenesis. We divided non‐small cell lung cancer (NSCLC) patients into nonsmoking and smoking groups with the aim of trying to understand the utility of brain‐specific angiogenesis inhibitor 1 (BAI1) expression in the separate groups. Methods Clinicopathological data were obtained from 148 patients who had undergone surgery for NSCLC of the lung. Tissue microarray blocks were made of samples from NSCLC patients. Two pathologists graded the intensity of BAI1 expression as high or low expression in the cancer cells of patients in the smoking and nonsmoking groups. Results NSCLC nonsmokers with higher BAI1 nuclear expression had poor disease‐specific survival (DSS) (hazard ratio: 2.679; 95% confidence interval [CI]:1.022–7.022, p = 0.045). The Kaplan–Meier survival curve confirmed that higher BAI1 expression was significantly associated with poor DSS (p = 0.034) in the nonsmoking group. Conclusions We divided NSCLC patients into nonsmoking and smoking groups and found that nuclear BAI1 expression was related to patient survival in nonsmoking NSCLC patients. We suggest BAI1 expression as a predictive marker of nonsmoking‐associated NSCLC and recommend that it be evaluated as an AJCC staging criterion in the future.

Abstract
RATIONALE Rosai-Dorfman disease (RDD) is a rare and self-limiting condition caused by the non-neoplastic proliferation of histiocytes/phagocytes in the sinusoids of lymph nodes and in extranodal tissues. Of the extranodal involvement, laryngeal involvement is extremely rare. Because of its rarity and nonspecific clinicoradiologic features, RDD is often difficult to differentiate from other benign or malignant lymphoproliferative diseases. We present a case of RDD with infiltration of IgG4-bearing plasma cells manifesting laryngeal and nasal masses with cervical lymphadenopathy. PATIENT CONCERNS A 45-year-old male patient presented with recurrent epistaxis and airway disturbance. DIAGNOSES On endoscopy, there were submucosal masses in both nasal cavities and both sides of subglottic larynx. On neck CT, there were well-defined, enhancing soft tissue masses in both nasal cavities and both sides of subglottic larynx, resulting in mild airway narrowing. In addition, multiple enlarged lymph nodes showing homogeneous enhancement were noted in both parotid glands and both internal jugular chains. All lesions demonstrated marked FDG-uptake on PET/CT. Therefore, the initial radiologic differential diagnoses included lymphoma and IgG4-related disease. Biopsy was performed on the nasal and laryngeal lesions, and they revealed RDD with infiltration of IgG4-bearing plasma cells. INTERVENTION The patient underwent surgical resection of the masses in the nasal cavity and larynx to relieve airway narrowing. OUTCOMES After surgery, airway obstruction was much improved and the patient was asymptomatic. On outpatient follow-up, he exhibited a stable condition and had no dyspnea on exercise. LESSONS Clinical awareness and suspicion are important for the accurate diagnosis and management of patients with homogeneous masses in the larynx or nasal cavity, even if there is no combined cervical lymphadenopathy.

Abstract
BACKGROUND Primary non-Hodgkin’s lymphoma of the frontal sinus is extremely rare. In addition, Epstein-Barr virus (EBV) has been reported to play a role in the development of human immunodeficiency virus (HIV)-related malignant lymphomas. To the best of our knowledge, there is no report for the HIV-associated, EBV-positive primary diffuse large B-cell lymphoma (DLBCL) in the frontal sinus.
CASE SUMMARY We present a unique case of HIV-associated, EBV-positive DLBCL in the frontal sinus in a 46-year-old man. Computed tomography of paranasal sinuses revealed dense opacification of the right frontal sinus with combined soft tissue swelling. Based on the clinical and radiological findings, the initial diagnosis was complicated frontal sinusitis, presenting Pott’s puffy tumor. Unexpectedly, HIV testing was positive on preoperative laboratory test, and the frontal sinus lesion was confirmed as EBV-positive DLBCL on biopsy.
CONCLUSION Through this article, we suggest that EBV-positive DLBCL should be considered as possible diagnosis for patients with nonspecific space-occupying lesion of the paranasal sinuses. We also highlight an importance of clinical suspicion in diagnosing HIV infection because HIV serology is not routinely tested in patients with paranasal sinus problem.

Abstract
Chronic intradiploic organizing hematoma of the skull is a rare lesion that usually presents as a progressively growing mass after head trauma, thus making it difficult to diagnose. To date, only nine cases that have been histopathologically confirmed as organizing hematoma of the skull have been reported in the literature. Herein, we describe a case of a chronic organizing hematoma involving the right parietal bone, presenting as a slowly growing mass in a 54-year-old man. The lesion was also visualized on magnetic resonance imaging (MRI) with a zero echo time sequence. In this case report, we emphasize that chronic intradiploic organizing hematoma should be considered in the differential diagnosis of a palpable scalp mass. We also highlight the importance of meticulous radiological review in the context of appropriate clinical suspicion and the usefulness of the zero TE sequence in evaluating calvarial lesions.

Abstract
Macrophage migration inhibitory factor (MIF) is a cytokine that mediates the interaction between malignant cells and the innate immune system. Recently, MIF has received attention for its role in tumorigenesis. We evaluated the prognostic role of MIF in clear cell renal cell carcinoma (CCRCC).A total of 152 patients, who underwent nephrectomy for CCRCC were enrolled in this study. Immunohistochemical staining of tissue microarray blocks containing 298 cores-2 cores per CCRCC patient was performed. The relationship between MIF expression and clinicopathological factors was evaluated. Total RNA and protein were extracted from 7 RCC (renal cell carcinoma) cell lines. MIF was knocked down in Caki-2 cells, and a wound healing assay was performed to evaluate migratory activity.Among the 298 cores, 180 (60.4%) were positive for MIF. Multivariate analysis, showed that, CCRCC patients with negative MIF expression exhibited poor disease-free survival (hazard ratio: 2.087, 95% confidence interval: 0.821-5.307, P value: .023) and poor disease-specific survival (hazard ratio: 2.101, 95% confidence interval: 1.009-4.374, P value: .047). The wound healing assay revealed that cell confluence was lower in MIF-deficient Caki-2 cells than in control cells.Negative MIF expression might be an independent prognostic marker for patients with CCRCC.

Abstract
RATIONALE Cavernous hemangioma is a benign vascular tumor, which very rarely occurs in the lung. When appearing as multiple nodules on chest CT, this tumor can be misdiagnosed as metastatic malignancy. PATIENT CONCERNS A 72-year-old woman presented with incidentally found multiple lung nodules on chest radiograph. DIAGNOSES Based on information derived from dual-layer spectral CT images, the possibility of slow flow vascular tumor such as cavernous hemangioma was suggested. A pathologic diagnosis of pulmonary cavernous hemangioma was made via video-assisted thoracoscopic biopsy. INTERVENTIONS After tissue confirmation, the patient was discharged without further intervention. OUTCOMES The patient recovered without any event. Follow-up chest CT performed 6 months later showed no significant interval change in nodule size and distribution. LESSONS Material decomposition images obtained from dual energy CT can help physicians understand the character of tumor vascularity for an accurate diagnosis of pulmonary cavernous hemangioma.

Abstract
BACKGROUND/AIM We aimed to evaluate the characteristics of gastric carcinoma with high excision repair cross complementing 1 (ERCC1) expression and the prognostic value of ERCC1 expression. MATERIALS AND METHODS ERCC1 expression was evaluated by immunohistochemistry in 309 surgically resected gastric carcinoma specimens using a tissue microarray. Cancer-related survival was analysed using competing risk analysis. RESULTS Compared to ERCC1-low gastric carcinomas, ERCC1-high gastric carcinomas showed less local invasion (p=0.0013), lower N stage (p=0.0302), earlier pTNM stage (p=0.0003), and less frequent recurrence (p=0002). Patients with ERCC1-high gastric carcinoma showed lower cumulative incidence function estimate of cancer-related death [3.37; 95% confidence intervaI (CI)=0.89-8.75] than did those with ERCC1-low gastric carcinoma (17.12; 95% CI=12.24-22.69; p-value by Gray's test=0.0012). Adjusted proportional sub-distribution hazard ratio for cancer-related death in the patients with ERCC1-high tumour was 0.272 (95% CI=0.084-0.878; p=0.0295). CONCLUSION High ERCC1 expression may be an independent positive prognostic marker for gastric carcinoma.

Abstract
Background Research on diagnosing recurrent non‐small cell lung cancer (NSCLC) and applying target gene treatment using exosomes in a less invasive way is very important. Recently, however, it has been argued that exosomes do not contain double‐stranded DNA (dsDNA) or histones. In this study, we describe the expression of extracellular vesicle (EV) markers in specimens from squamous cell carcinoma (SCC) of the lung and analyze their relationship with the prognosis of patients. Methods Clinical and pathological data were obtained from 96 patients who had undergone surgery for SCC of the lung. Tissue microarray blocks were made using representative paraffin blocks of samples from patients with SCC of the lung. Two pathologists graded the intensity of CD63, CD9, LC3A/B, P62, and ANXA1 expression as high or low expression. In addition, the authors designated the combined expression of these five independent markers as “positive EV expression” in this article. Results SCCs with low CD63 and SCCs with low EV expression showed unfavorable disease‐free survival (DFS) (P‐value = 0.037 and 0.006, respectively) in the survival analysis. The Kaplan‐Meier survival curve confirmed that the low EV expression showed a statistically significant relationship with unfavorable DFS (P‐value = 0.004). There were no statistically significant differences in DFS and disease‐specific survival in each low and high expression group for CD9, LC3A/B, ANXA1, and P62 in the Cox regression analysis. Conclusions As EV expression was related to the prognosis of lung SCC patients, a broader approach using different extracellular vesicles rather than a conventional exosome‐dependent one is needed.

Abstract
BACKGROUND There have been many attempts to predict the prognosis of lung cancer based on the expression patterns of P16 protein, but with limited success. The Eighth American Joint Committee on Cancer (AJCC) for head and neck cancer recently developed new criteria for evaluating P16 expression. Here, we applied these new criteria to evaluate the prognosis of non-small cell lung cancer (NSCLC). MATERIALS AND METHODS A total of 148 patients who had undergone surgery for NSCLC were enrolled in the study. P16 protein expression patterns from NSCLC tissue microarray samples were examined by immunohistochemical analysis. The Eighth AJCC head and neck cancer staging criteria were used to evaluate positive P16 expression (moderate/strong nuclear expression intensity and distribution >75% cells) in NSCLC. The relationship between P16 expression and clinicopathological factors were evaluated and survival analysis was included. RESULTS Negative P16 expression was significantly associated with NSCLC with lymph node metastasis (p=0.025). In addition, patients with NSCLC with negative P16 expression demonstrated poor disease-free and disease-specific survival in multivariate analysis. The Kaplan-Meier survival curve confirmed that negative P16 expression was significantly correlated with a poor disease-free survival (p=0.017) and disease-specific survival (p=0.016). CONCLUSION P16 expression defined with the new AJCC criteria is useful for detecting lymph node metastasis in NSCLC.

Abstract
OBJECTIVES To evaluate the predictive value of virtual monoenergetic images (VMIs) by assessing tumor conspicuity on dual-layer spectral detector CT (SDCT) and correlate tumor conspicuity on VMI with prognostic biomarkers in patients with breast cancer. METHODS Sixty-four patients underwent arterial phase and 90-s delayed phase dual-layer SDCT. A retrospective tumor conspicuity analysis of 14 benign tumors and 65 breast cancers was performed using conventional images (CIs) and VMI at 40 keV (VMI40) on arterial and delayed phase scans (CIART, VMI40ART, CIDE, VMI40DE). Mean Hounsfield units (HU) of tumors were measured on VMI40ART and VMI40DE. A receiver operating characteristic (ROC) curve analysis was performed to compare diagnostic accuracy between image sets. Estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki67 levels were evaluated using histopathology. Correlations between VMI analyses and histological characteristics of cancers were analyzed. RESULTS Cancers on VMI40 had a significantly higher conspicuity score and mean HU than benign tumors (p < 0.001). VMI40DE showed the highest conspicuity for cancers (mean, 3.79) and the greatest area under the ROC curve (0.817; 95% confidence interval 0.745-0.889). VMI40DE yielded significantly higher mean HU for cancers than VMI40ART (p < 0.001). The conspicuity score and mean HU on VMI40ART were significantly higher in cancers with ER negativity, PR negativity, and Ki67 positivity (p < 0.05). CONCLUSIONS VMI40DE may be useful in the diagnosis of breast cancers due to higher tumor conspicuity and better enhancement than VMI40ART. VMI40ART may be beneficial for the prediction of poor breast cancer prognoses. KEY POINTS • VMI40 improved conspicuity of breast cancer than CI. • VMI40DEyielded higher diagnostic performance of breast cancer than VMI40ART. • VMI40ARThas an additional benefit in terms of prognosis prediction in patients with breast cancers.

Abstract
Background and Objectives: To investigate the diagnostic performance of F-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) and subsequent ultrasonography (US) for determining cervical nodal metastasis in oncology patients. Materials and Methods: Fifty-nine cervical lymph nodes (LNs) initially detected by PET/CT with subsequent neck US were included in this retrospective study. All LNs were subjected to US-guided fine-needle aspiration or core needle biopsy. The maximum standardized uptake value (SUVmax) and sonographic features were assessed. Results: Forty-three of 59 cervical LNs detected by PET/CT were malignant. PET/CT alone showed a highest diagnostic value for metastatic LNs with 81.4% sensitivity, 68.8% specificity, and 78% accuracy when SUVmax ≥5.8 was applied as an optimal cut-off value. Combined PET/CT and subsequent US diagnoses for determining nodal metastasis showed the following diagnostic performance: 81.4% sensitivity, 87.5% specificity, and 83.1% accuracy. There was a significant difference in the diagnostic performance between the two diagnostic imaging approaches (p = 0.006). Conclusions: Combined diagnosis using subsequent US showed a significantly higher diagnostic performance for determining nodal metastasis in the neck. Therefore, we believe that our proposed diagnostic strategy using subsequent US can be helpful in evaluating cervical LNs on PET/CT. Moreover, our results clarify the need for US-guided tissue sampling in oncology patients.

Abstract
BACKGROUND/AIM Multiple primary malignant tumors are common in patients with renal cell carcinoma. However, reports on the factors that can identify patients with a risk for subsequent primary malignancies have been lacking. This study aimed to investigate whether myoferlin expression can be used as a potential marker to predict subsequent primary malignancies in patients with clear cell renal cell carcinoma (ccRCC). MATERIALS AND METHODS We evaluated the relationship of subsequent primary malignancies with clinicopathological factors and myoferlin expression in 152 patients with ccRCC, and we analyzed the strength of the association with myoferlin expression. RESULTS The development of subsequent primary malignancies exhibited significant correlation with patient age (p=0.029), sex (p=0.015), T stage (p<0.001), and myoferlin expression (p=0.017). Furthermore, myoferlin hyperexpression was determined as an independent risk factor for developing a subsequent primary malignant tumor in patients with ccRCC (odds ratio(OR), 2.485, 95% Confidence Interval(CI)=1.052-5.870, p=0.038). CONCLUSION Myoferlin hyperexpression can be a useful marker for predicting the development of subsequent primary malignancies in patients with ccRCC.

Abstract
RATIONALE Immunoglobulin G4-related disease (IgG4-RD) is regarded as an immune-mediated systemic fibroinflammatory disease. Several studies have linked IgG4-RD to infections such as tuberculosis and actinomycosis. However, the coexistence of IgG4-RD and non-tuberculous mycobacterium (NTM) in a single pulmonary nodule has not been reported yet. PATIENT CONCERNS A 76-year-old male patient presented with cough and sputum. A solitary pulmonary nodule suspicious of lung cancer was found on chest CT. DIAGNOSIS Through video-assisted thoracoscopic biopsy, a diagnosis of co-existing NTM and IgG4-RD in a single nodule was made. INTERVENTIONS Antibiotic treatment was applied for pneumonia developed after surgery. The patient was also supported by extracorporeal membrane oxygenation and mechanical ventilation since his pneumonia was refractory to medical treatment. OUTCOMES The patient expired on the 60th postoperative day due to multiple organ failure. LESSONS IgG4-RD can occur singularly or accompanied by other diseases. We report a solitary pulmonary nodule caused by NTM and concurrent IgG4-RD, suggesting a possible association between these 2 entities. Immunologic relations between IgG4-RD and accompanying infection should be further investigated.

Abstract
S100A9 was originally regarded as a regulator of immune response and a mediator of the inflammatory process. Recent studies have suggested that S100A9 expression plays an important role during tumor development, progression and metastasis in various cancers. The present study aimed to investigate the expression and prognostic role of S100A9 in clear cell renal cell carcinoma (ccRCC).S100A9 expression was examined by immunohistochemical staining in 152 patients who underwent surgical resection due to ccRCC. The correlation between S100A9 expression and clinicopathological data and its prognostic role were evaluated in patients with ccRCC.S100A9 revealed high expression in 37 cores (12.6%) of ccRCC. S100A9 expression was significantly associated with T stage (P < .001) and Fuhrman nuclear grade (P < .001), but not with patient age (P = .821) and sex (P = .317). Survival analysis revealed that high S100A9 expression is an independent factor for unfavorable disease-free survival (hazard ratio, 2.423; 95% confidence interval, 1.044-5.621; P = .039) and disease-specific survival (hazard ratio, 2.428; 95% confidence interval, 1.130-5.214; P = .023) in patients with ccRCC.S100A9 expression can be a useful prognostic factor in patients with ccRCC.

Abstract
BACKGROUND/AIM S100A8 is a chemoattractant known to be associated with metastatic niche formation. Herein, we evaluated the prognostic value of S100A8 in patients with clear cell renal cell carcinoma (CCRCC). MATERIALS AND METHODS A total of 152 CCRCC patients who have undergone nephrectomy were enrolled. The expression of S100A8 was assessed immunohistochemically using tissue microarray (TMA) blocks of CCRCC. Using statistical analysis, the relationship between S100A8 expression and clinicopathological factors was evaluated. RESULTS Among 152 TMA cores, 21 (6.9%) showed higher S100A8 expression. S100A8 expression was significantly increased in cores of patients with higher T stage (≥2, p<0.001) and higher Fuhrman nuclear grade (≥3, p<0.001). Multivariate analysis confirmed that high expression of S100A8 was significantly correlated to poor disease-free survival (hazard ratio, 2.601; 95% confidence interval (CI), 1.020-6.628; p-value=0.045). CONCLUSION S100A8 expression may have a prognostic value in CCRCC reflecting TNM staging and Fuhrman nuclear grade.

Abstract
BACKGROUND Apolipoprotein E (APOE) modulates lipid homeostasis in the systemic circulation and induces inflammatory immune responses in the tumor microenvironment. We evaluated APOE expression in order to assess tumor progression in non-small cell lung cancer (NSCLC). METHODS Immunohistochemical staining for APOE was performed on tissue microarray blocks from 148 patients who had undergone surgery for NSCLC. The staining intensity and the proportion of APOE-positive tumor cells (based on distinct membranous and cytoplasmic staining) were scored. The relationships between APOE expression and clinical (age, sex, and smoking history) and pathological (TNM stage and histological type) factors were evaluated. RESULTS Positive APOE staining was observed in 93 (64.6%) patients. APOE expression patterns differed among NSCLC histological types (p-value = 0.016). Negative APOE expression was significantly associated with lymph node metastasis in NSCLC (p-value = 0.040). Both cases of N2 (stage IIIA) disease showed negative APOE expression. CONCLUSIONS APOE is a useful marker for assessing NSCLC patients with lymph node metastasis.

Abstract
BACKGROUND AND AIMS Atherosclerosis is a prominent vascular lesion, and potentially causing ischemic alterations in the brain and heart. Recent studies have reported that physiological and pathological alterations in atherosclerosis and extracellular vesicles (EV) are related. This study aimed to investigate the association between the extent of atherosclerotic lesions and the number of serum EVs in a mouse model of atherosclerosis (wild-type). METHODS Eighteen 3-week-old C57BL/6 N male mice(wild-type) were purchased. Twelve mice were fed a 45% high-fat diet (HFD) for six months. Six mice were provided standard laboratory chow for six months. The entire aorta, from the aortic sinus to the division of the iliac artery, was dissected out from each mouse. Furthermore, the degree of atherosclerosis was microscopically determined. Serum EVs were quantified by size via nanoparticle tracking analysis. RESULTS The number of EVs in the high-atherosclerotic score group (1.43 × 109) was higher than that in the low- atherosclerotic score group (0.7 × 109) in the range of 211.5-222.5 nm (p = 0.033). CONCLUSIONS Enumeration of EVs is a potential method of detecting atherosclerosis.

Abstract
Re‐expansion pulmonary edema is a rare complication that may occur after chest drainage performed for pneumothorax. This condition manifests as areas of ground‐glass opacities (GGO) and septal thickening on imaging studies. In the case reported here, chest computed tomography (CT) showed diffuse ground‐glass opacity secondary to ruptured bullae in a patient who underwent chest tube drainage for pneumothorax, suggesting re‐expansion pulmonary edema. Histopathological examination of lung tissue resected from the vicinity of the bullae showed focal adenocarcinoma, which was masked by re‐expansion pulmonary edema on preoperative computed tomography. Right upper lobectomy with mediastinal lymph node dissection was performed on postoperative day 3.

Abstract
OBJECTIVES Poor wound healing as reflected by the development of synechia and osteitis after endoscopic sinus surgery may trigger disease recurrence. Animal models provide insights into the pathogenesis of poor wound healing and may aid in the development of new therapeutics. Here, we established a mouse model of nasal wound healing and confirmed its utility. STUDY DESIGN Animal study. METHODS Unilateral intranasal wounds were induced using a small interdental brush in 6-week-old C57BL/6 mice. Forty-five mice were divided into three groups (each n = 15): one control and two experimental groups (intranasal vs. intraperitoneal dexamethasone). Mice were sacrificed on days 2, 14, and 28 after injury (each n = 5). Serial changes in nasal wound histopathology were described, and intergroup differences were analyzed. RESULTS On day 2, mucosal detachment, hemorrhage, and exudate were observed. On day 14, synechiae featuring neo-osteogenesis (bone lacunae, osteoblasts, and multinucleated osteoclasts) between the septum and the maxilloturbinate were prominent, followed by wound maturation on day 28: fewer lacunae and smaller osteoblasts. Macrophages were evident only on day 2, and lymphocytes were predominant on day 28. The amount of exudate on day 2 and the synechial area on day 28 were significantly reduced in mice that received dexamethasone systemically compared with control mice, with similar trends in those treated intranasally. CONCLUSION Our mouse model of nasal wound healing was characterized by the development of bony synechia and neo-osteogenesis, not soft-tissue synechia. The model may be useful in the assessment of novel therapeutics to prevent those wounds. LEVEL OF EVIDENCE NA Laryngoscope, 129:E266-E271, 2019.

Abstract
AIM To examine the expression of RAB27A and RAB27B in clear cell renal cell carcinoma (CCRCC). MATERIALS & METHODS The intensity and proportion of tumor cells staining positive for RAB27A and RAB27B in a total of 304 cores were evaluated. RESULTS The T stage showed a significant correlation with RAB27A intensity (p < 0.001). In multivariate analysis, CCRCC with negative intensity of RAB27A expression demonstrated poor disease-specific survival (hazard ratio: 6.821, 95% CI: 1.128-41.241; p-value = 0.036). CONCLUSION RAB27A is an independent prognostic factor in CCRCC.

Abstract
Background S100A8 and S100A9 have been gaining recognition for modulating tumor growthand metastasis. This study aimed at evaluating the clinical significance of S100A8 and S100A9 innon-small cell lung cancer (NSCLC). Methods We analyzed the relationship between S100A8and S100A9 expressions, clinicopathological characteristics, and prognostic significance in tumorcells and peritumoral inflammatory cells. Results The positive staining of S100A8 in tumorcells was significantly increased in male (p < .001), smoker (p = .034), surgical method other thanlobectomy (p = .024), squamous cell carcinoma (SQCC) (p < .001) and higher TNM stage (p = .022)compared with female, non-smoker, lobectomy, adenocarcinoma (ADC), and lower stage. Theproportion of tumor cells stained for S100A8 was related to histologic type (p < .001) and patientsex (p = .027). The proportion of inflammatory cells stained for S100A8 was correlated with patientage (p = .022), whereas the proportion of inflammatory cells stained for S100A9 was correlatedwith patient sex (p < .001) and smoking history (p = .031). Moreover, positive staining in tumorcells, more than 50% of the tumor cells stained and less than 30% of the inflammatory cellsstained for S100A8 and S100A9 suggested a tendency towards increased survivability in SQCCbut towards decreased survivability in ADC. Conclusions S100A8 and S100A9 expressions might be potential prognostic markers in patients with NSCLC.

Abstract
RATIONALE Lymphatic embolization is a minimally invasive treatment option for managing chyle leakage after nodal dissection in the neck. After the procedure, the embolic material may cause foreign body granulomatous lymphadenitis and can be a diagnostic challenge for radiologists because of sonographic similarity to metastatic lymph node. Herein, we describe a clinical case of granulomatous lymphadenitis due to embolic material mimicking nodal metastasis detected on ultrasonography (US) with cytologic findings in a patient with thyroid cancer who underwent lymphatic embolization to treat chyle leakage after total thyroidectomy and neck dissection. We also review the relevant literature regarding this disease with technical background of the procedure and suggest the importance of clinical suspicion in diagnosing the granulomatous lymphadenitis in patients with a history of lymphatic embolization. PATIENT CONCERNS A 40-year-old man who underwent total thyroidectomy and bilateral modified radical neck dissection due to papillary thyroid carcinoma had suspicious cervical lymph node on US after lymphatic embolization of chyle leakage. DIAGNOSES The suspicious cervical lymph node proved to be foreign body granulomatous lymphadenitis due to embolic material by US-guided fine-needle aspiration. INTERVENTIONS The patient did not undergone additional surgery because the pathologic cervical lymph node was confirmed to be foreign body granulomatous lymphadenitis. OUTCOMES The patient is being followed up regularly at the outpatient department. LESSONS Clinical awareness of the technical background of lymphatic embolization and possible sonographic features of granulomatous lymphadenitis is important for an accurate diagnosis and the appropriate management in patients who underwent lymphatic embolization.

Abstract
RATIONALE Brachial plexus schwannomas are rare benign tumors that are derived from Schwann cells. Because they are rare, and because of the complexity of the anatomy of the neck, these tumors can be a challenge to diagnose for radiologists and clinicians. In the present study, we describe a clinical case of brachial plexus schwannoma detected on ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), and presenting as a palpable neck mass. PATIENT CONCERNS A 49-year-old woman had a palpable mass in the right neck, which had been there for the last 1 year. Metastatic cervical lymphadenopathy was suspected in the primary health clinic; therefore, the patient was referred to our hospital. DIAGNOSES The right neck mass was a well-circumscribed oval soft tissue mass on US, CT, and MRI. US-guided core needle biopsy was performed and the mass was proved to be a schwannoma. INTERVENTIONS The patient did not undergo surgical excision because the brachial plexus schwannoma was small and there was no accompanying neurological symptom. OUTCOMES The patient is being followed up regularly at the outpatient department. LESSONS Brachial plexus schwannoma should be considered for a differential diagnosis in patients with a palpable neck mass, and imaging studies play an important role in diagnosing the brachial plexus schwannoma.

Abstract
A ‘collision’ tumor refers to the existence of two different neoplasms within the same tumor. Sometimes, the term ‘biphasic tumor’ is also used. However, a ‘collision’ tumor is defined as the occurrence of two neoplasms within proximity of each other yet maintaining distinctly defined, separate boundaries. In contrast, a ‘biphasic’ tumor demonstrates two or more phenotypically distinct neoplastic cell populations merging within the same space. Here, we report a case of collision tumor associated with sarcomatoid eccrine porocarcinoma and basal cell carcinoma arising in a 57-year-old male patient.

Abstract
Nonsecretory multiple myeloma is a rare variant of multiple myeloma characterized by the proliferation of clonal plasma cells in the bone marrow. It is difficult to establish an early and accurate diagnosis of nonsecretory multiple myeloma because in nonsecretory myeloma cases, monoclonal immunoglobulin cannot be detected in the serum or urine via electrophoresis. In this report, we describe a case of nonsecretory multiple myeloma presenting as recurrent vertebral compression fractures in a 70-year-old male patient and suggest that nonsecretory multiple myeloma can be included in the differential diagnosis of multiple and recurrent vertebral compression fractures, despite the lack of detectable monoclonal immunoglobulin in the serum or urine by electrophoresis.
