Abstract
Background: Congenital triangular alopecia (CTA) is a benign, asymptomatic, nonprogressive, localized and noncicatricial type of alopecia that is usually first noted during infancy or childhood. The pattern of hair loss is traditionally described as triangular, oval or lancet shaped with apex toward the vertex.
Objectives: We present a case series of CTA located in unusual sites.
Patients and Methods: We performed trichoscopy in 78 patients with CTA. From this group, we selected 10 individuals (4 males and 6 females) whose disease was not localized on the typical scalp area.
Results: The alopecic area was located on the occipital region in 5 patients, the parietal region in 4 patients, at the vertex in 1. With trichoscopy, vellus hairs were detected in all patients, and evidence of empty follicles was noticed only in 3 patients.
Conclusions: In contrast with the preconceived notion that all CTAs are frontotemporal, our case series points out that this disease could be localized in other scalp sites.

The Role of Trichoscopy in Keratosis Follicularis Spinulosa Decalvans: Case Report and Review of the Literature. Skin Appendage Disord 2020; 7:29-35. [PMID: 33614716 DOI: 10.1159/000510525] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Accepted: 07/27/2020] [Indexed: 11/19/2022] Open
Abstract
Introduction Keratosis follicularis spinulosa decalvans (KFSD) is a rare, X-linked, hereditary disorder of keratinization, characterized by skin involvement and progressive scarring alopecia of scalp, eyebrows, and eyelashes. The diagnosis is helped by the particular clinical features, but pathology is mandatory. Case Presentation We described a case of a female patient referred to the outpatient's hair consultation of our department, in which we performed trichoscopy as a very useful tool for the diagnosis, followed by pathology that confirmed KFSD. Conclusion In our article, we underlined the importance of trichoscopy for the diagnosis of this hair disease, with also a review of the literature on diagnosis and treatment.

Abstract
Ibrutinib is a Burton tyrosine kinase inhibitor (BTKi) approved for the treatment of several hematologic malignancies. Analyze skin adverse events (SAE). All the patients treated with Ibrutinib featuring cutaneous adverse events were selected. Twenty five patients were retrieved with a median interval between Ibrutinib start and SAE time of onset of 120 days. Most common SAE observed involved hairs and nails. Eczematous reaction and leucocytoclastic vasculitis were also detected. One patient had a long-history Ibrutinib treatment and experienced numerous cutaneous adverse events. Infective disease such as superficial mycosis and impetigo were rarely present in our series. Despite the development of cutaneous SAE, all the patients continued their concomitant drugs without the onset of any further SAE. Our data suggest Ibrutinib-associated rash should be distinguished in early and late events and a careful dermatologic management of patients should be scheduled.

Intralesional steroid treatment for the intermediate stage of retronychia: A pilot study. Dermatol Ther 2020; 33:e14174. [PMID: 32779351 DOI: 10.1111/dth.14174] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 08/06/2020] [Accepted: 08/07/2020] [Indexed: 01/08/2023]
Abstract
Retronychia describes the proximal ingrowing of the nail plate. In the early stage, topical steroids are the gold standard therapy, while in the late stage surgical treatment is mandatory. We identified an intermediate severity stage of retronychia, where the topical treatment alone is ineffective and surgery is avoidable. Intralesional steroids turn the best treatment in these patients. A pilot study consisting of a 3-month treatment period and 9-month follow-up time was designed to evaluate the treatment outcome to intralesional steroid injections in patients affected by the intermediate-stage of toenail retronychia. The complete recovery of retronychia-associated nail abnormalities was observed in 27/28 recruited patients at the end of the treatment phase. Paronychia, nail plate discoloration, proximal nail fold (PNF) elevation, and discharge were reduced (P < .01) after one steroid administration, while nail regrowth became significant after two sessions. No significant difference in terms of clinical outcome was found, while pain VAS score and intra-operative pain evaluated with Wong-Baker faces scale were higher in the female group (P < .01). Limitation Lack of control group of patients. Despite its temporary effect, the intralesional triamcinolone injection is an effective, cheap, and safe treatment especially for the intermediate stage of retronychia.

Scalp hair whorl patterns in patients affected by Neurofibromatosis Type 1: A case-control study. Int J Trichology 2020; 12:56-61. [PMID: 32684676 PMCID: PMC7362971 DOI: 10.4103/ijt.ijt_25_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 03/14/2020] [Accepted: 03/21/2020] [Indexed: 11/04/2022] Open
Abstract
Background The hair whorl denotes the spiral disposition of hairs around an axis, which is determined by the follicle growing direction. Atypical variants of scalp hair patterns, identified by abnormally placed or multiple whorls, have been associated with early brain developmental disorders and several dysmorphic syndromes. Materials and Methods A 6-month case-control, prospective monocentric study included an overall number of 557 children. A logistic regression analysis was performed to evaluate the relationship between localization, the number of scalp hair whorls, and their association with neurofibromatosis type 1 (NF1). Results NF1 positively correlates with a frontal localization, whereas a negative association was found with a parietal whorl pattern (P < 0.001). Conclusion Evaluation of scalp whorls gains importance in the neonatal settings and may contribute to suspect the early diagnosis of NF1, as the related National Institutes of Health diagnostic criteria cannot be usually observed at an early age.

Abstract
BACKGROUND A new propylene glycol (PG)-free 5% minoxidil (Mnx) lotion has been recently commercialized. Aim of this study was to evaluate the acceptability/tolerability and clinical efficacy of 3-month application of this new PG-free Mnx lotion and the penetration of the active compound in a reconstructed human epidermis (RHE/Episkin) model in comparison with a PG Mnx 5% lotion. METHODS Thirty subjects of both sex with a diagnosis of AGA were enrolled in the trial. Cosmetic acceptability and clinical efficacy were evaluated after 4, 8 and 12 weeks of treatment. Global tolerability was evaluated at week 12. Cosmetic acceptability evaluation was assessed using a 7-item questionnaire using a 10-point scale score. Global Tolerability was evaluated with a 4-grade scale. Clinical efficacy was evaluated with a 5-grade scale. Skin absorption of PG-free Mnx was evaluated and compared with a PG Mnx solution using the Episkin model. RESULTS All subjects concluded the study. The 7-item questionnaire mean values were always <2 at each time-point evaluation, demonstrating high cosmetic acceptability/tolerability. No subjects reported burning, itching or redness sensations. Global Tolerability score mean±SD value was 1.7±0.4. Clinical efficacy scores were 0.4, 0.6 and 1.2 at week 4, 8 and 12, respectively. PG-free Mnx showed similar amount of absorbed dose in comparison with PG Mnx. CONCLUSIONS This new PG-free lotion shows a very good cosmetic acceptability/tolerability profile. Clinical efficacy was also documented. The skin penetration of this formulation is comparable to the PG Mnx lotion, supporting the bioequivalence of the two products.

Abstract
There are few data on the virological characterisation of patients with failure to current-generation direct-acting antivirals (DAAs), namely elbasvir/grazoprevir, sofosbuvir/velpatasvir and glecaprevir/pibrentasvir. This study aimed to characterise virological patterns in patients with failure to current DAA regimens as well as the efficacy of re-treatment. All 61 consecutive hepatitis C virus (HCV) treatment-naïve patients with failure to current DAAs from January 2018 to February 2019 were enrolled. Sanger sequencing of NS3, NS5A and NS5B proteins was performed using homemade protocols. NS5A resistance-associated substitutions (RASs) were more frequent in the 17 patients treated with sofosbuvir/velpatasvir (89.5%) and 33 patients treated with elbasvir/grazoprevir (97%) compared with the 11 patients treated with glecaprevir/pibrentasvir (18.2%) (P = 0.002 and 0.000, respectively). NS3 RASs were more often detected in the 33 patients with failure to elbasvir/grazoprevir (30.3%) than in the 11 patients treated with glecaprevir/pibrentasvir (9.1%). NS3 RASs were also detected in 12% of sofosbuvir/velpatasvir-treated patients. NS5B RASs were infrequently identified. Of the glecaprevir/pibrentasvir-treated patients, 73% did not show RASs in any HCV regions, a prevalence higher than that observed in those treated with elbasvir/grazoprevir (0%; P < 0.05) or sofosbuvir/velpatasvir (12%; P < 0.05). Of the 61 patients, 21 (34.4%) were re-treated with sofosbuvir/velpatasvir and voxilaprevir. All patients achieved sustained virological response at 12 weeks (SVR12). To our knowledge, this is one of the first real-life studies describing patients who failed current-generation DAAs; the prevalence of RASs differed according to the DAA regimen used, and the efficacy of re-treatment was high.

Abstract
BACKGROUND Nail tumors often pose a significant challenge for the clinician, as they are burdened by a high delay in diagnosis and paucity of clinical signs in the early stage. In most cases, the onset of pain or nail plate dystrophy leads to imaging investigations such as plain radiography, magnetic resonance imaging, and ultrasonography (US) when surgery is pending. MATERIAL AND METHODS A 2-year monocentric study evaluated the histologically confirmed cases of subungual glomus tumor (GT) and squamous cell carcinoma (SCC) with a pre-surgical US assessment, and reviewed their sonography features. A total of 7 digital GTs and 6 SCCs of the nail were collected. RESULTS GT and SCC are easily distinguishable on US. Compared to SCC, GT was positively associated with an ovoid shape, well-defined borders, bone cup-scalloping without cortical erosion, and a rich intralesional vascular pattern (P < 0.05). Vice versa, SCC was significantly correlated with irregular shape, ill-circumscribed margins, an infiltrative growth pattern with peripheral hypoechoic foci, posterior acoustic shadow, cortical erosion, and a highly vascular multipolar peripheral pattern (P < 0.05). CONCLUSION The rapid assessment of GT and SCC sonographic features may contribute to reduce diagnostic delay, expedite management, and decrease the risk of surgical relapse.

Abstract
Nivolumab, a fully human IgG4 immune checkpoint modulator, binds to the programmed cell death 1 (PD-1) receptor on T cells and blocks their inhibition. Thus, it increases the anticancer host immune response by allowing T cells to attack tumor cells. Although anti-PD-1 immunotherapy is typically well accepted, deregulation of immune tolerance caused by nivolumab may determine immune-related adverse events, among which skin toxicities represent the most common. We report a case of severe new-onset palmoplantar and nail psoriasis after receiving nivolumab treatment for metastatic melanoma.

Abstract
Background Yellow nail syndrome is a rare condition characterized by typical nail alterations and variable presence of lymphedema and respiratory disease. The pathogenesis is still obscure, with most of the literature deriving from case reports and few investigations. The most reported respiratory conditions associated with yellow nail syndrome are pleural effusion and bronchiectasis, whereas association with rhinosinusitis is rarer. Objectives To describe a case of yellow nail syndrome and to provide a literature review regarding this disorder, discussing pathogenetic hypothesis, associated conditions, and therapeutic options. Patients/Methods A 49-year-old man presented with arrested growth and alterations of his nails, without any history of previous trauma or inflammation but with a severe nasal septum deviation and a history of chronic rhinosinusitis. A diagnosis of yellow nail syndrome was made. Results Six months after undergoing rhinoseptoplasty and treatment with oral vitamin E, the patient's nails were cured. Conclusions This case emphasizes the role of the dermatologist in detecting systemic conditions. The correct diagnosis led to complete resolution of both nail alterations and associated respiratory disorders.

Abstract
INTRODUCTION Brittle nail syndrome is characterized by dry, weak, easily breakable nails that show inelasticity, splitting and overall nail plate fragility. OBJECTIVE This paper describes in vitro and clinical studies using bovine hooves designed to assess the efficacy, compatibility and acceptability of a water-soluble nail strengthener (WSNS), containing Pistacia lentiscus and hyaluronic acid, for the treatment of patients affected by brittle nails. METHODS In the in vitro study, the WSNS was tested versus placebo and a marketed product on bovine hoof membranes, applied once daily for 14 days for evaluation of firmness, viscoelasticity and thickness before and after applications. In a clinical study, 23 female subjects affected by brittle nails were included, and the WSNS was applied once daily for 3 months. Signs and symptoms were rated by the investigators and by the participants during treatment at 28 and 84 days with different methods and dermoscopic images. Subjective efficacy was evaluated by specific questionnaires. RESULTS In the in vitro study, the daily application of the WSNS and marketed product led to a significant increase in firmness index. In the clinical study, the nails on the treated hand presented an improvement in nail appearance and weakness, after 28 and 84 days of WSNS application, respectively. The nails not treated showed no improvement. The WSNS was well tolerated. CONCLUSIONS The WSNS containing Pistacia lentiscus and hyaluronic acid was shown to significantly increase nail firmness in the in vitro study. In the clinical study, WSNS significantly improved brittle nail appearance. The hydrosolubility and easy-to-apply format of WSNS were reported to be factors of a good compliance. We consider this product as an important tool to improve and reinforce the aspect of brittle nails.

Abstract
Lichen planus is a benign inflammatory disorder of unknown etiology that may affect the skin, mucosae, scalp, and nails. When the nails are affected, it may lead to permanent destruction with severe functional and psychosocial consequences. Therefore, prompt diagnosis and early treatment are essential, even in mild cases. There are currently no guidelines for the management of nail lichen planus and the published literature on treatment is limited. The aim of this review is to provide practical management recommendations for the classical form of nail lichen planus, especially when restricted to the nails. Topical treatment has poor short-term efficacy and may cause long-term side effects. Instead, intralesional and intramuscular triamcinolone acetonide should be considered first-line therapies. Oral retinoids are second-line choices, and immunosuppressive agents may also be considered.

Abstract
BACKGROUND Erosive pustular dermatosis of the scalp (EPDS) is characterized by crusted erosions or superficial ulcerations that lead to scarring alopecia. OBJECTIVES AND METHODS We performed a multicentre retrospective clinical study including 56 patients (29 females and 27 males, mean age 62.7) with a confirmed EPDS in order to describe epidemiology, clinical findings and therapeutic choices of this disease. RESULTS Mechanical/chemical trauma was reported in 28.6%, a previous infection in 10.7%, a previous cryotherapy in 5.4% androgenetic alopecia in 48.2% and severe actinic damage in 25%. Trichoscopy showed absence of follicular ostia, tufted and broken hair, crusts, serous exudate, dilated vessels, pustules and hyperkeratosis. Histopathology revealed three different features, depending on the disease duration. The most prescribed therapy was topical steroids (62.5%), followed by the combination of topical steroids and topical tacrolimus (8.9%), systemic steroids (7.1%) and topical tacrolimus (5.4%). A reduction of inflammatory signs was observed in 28 patients (50%) treated with topical steroids and in all three patients treated with topical tacrolimus. CONCLUSION The relatively high number of patients collected allowed us to identify a better diagnostic approach, using trichoscopy and a more effective therapeutic strategy, with high-potency steroids or tacrolimus, which should be considered as first-line treatment.

Abstract
Female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women. The onset may be at any age following puberty and the frequency increases with age. Clinically, it shows a diffuse hair thinning over the central scalp, while the frontal hairline is usually retained. FAGA can have a significant psychological impact, leading to anxiety and depression. For this reason, early diagnosis is very important to stop the progression of the disease. The sex hormonal milieu is the main pathogenetic mechanism studied in FAGA. The role of androgens is not clearly defined and only one-third of women with FAGA show abnormal androgen levels. Endocrinological diseases with hyperandrogenism associated with FAGA comprise polycystic ovarian syndrome (PCOS), hyperprolactinemia, adrenal hyperplasia and, rarely, ovarian and adrenal tumours. Usually the diagnosis of FAGA is made clinically. A complete clinical examination and a blood examination can reveal other signs of hyperandrogenism. Trichoscopy shows the typical hair miniaturization. A scalp biopsy can be useful when the clinical evaluation does not provide a definitive diagnosis or when cicatricial alopecias with hair loss in the distribution of FAGA or alopecia areata are suspected. FAGA is a slowly progressive disease. The goal of therapy is to stop the progression and to induce a cosmetically acceptable hair regrowth. The most important drugs are topical minoxidil and oral anti-androgens. The purpose of this review is to provide an update on FAGA and to create a guideline on diagnosis and management of this frequent hair disease, not always easily recognizable from cicatricial alopecias with a similar distribution.

Abstract
Nail plate brittleness (or fragility) is a common complaint affecting up to 20% of the population, especially women over 50 years of age, with fingernail fragility being more prevalent than toenail fragility. Nail brittleness is characterized by nails that split, flake and crumble, become soft and lose elasticity. The main clinical presentations are: onychoschizia, onychorrhexis, superficial granulation of keratin and worn-down nails. According to causative factors, we can distinguish 2 forms of nail fragility (NF): a primary "idiopathic or brittle nail syndrome" form and NF secondary to different causes such as inflammatory nail disorders, infections, systemic diseases and general conditions, traumas and alteration of the nail hydration. Optimal management requires treatment of the primary cause of brittle nails, when possible. In idiopathic NF oral supplementation, vitamins (especially biotin, also known as vitamin B7), trace elements and amino acids (especially cysteine) have been reported to be useful. In addition, several products, such as topical moisturizers and lacquers could be considered to restructure the affected nail plate and to reduce psychological impacts of this common problem.

Abstract
INTRODUCTION Brittle nails are fragile or split nails; they affect 20% of the population and may be primary or secondary to different conditions. The aim of our studies was to evaluate the efficacy and tolerability of a new water-based nail-strengthening treatment containing hyaluronic acid and Pistacia lentiscus with daily application for a period of 1-3 months for one study (n = 30) and up to 6 months for a second study (n = 30). METHODS In total, we enrolled 60 patients of both sexes with brittle and weak nails due to primary or secondary causes and evaluated the efficacy of this new product using subjective and objective methods: clinical evaluation, assessment of photographs, onychoscopy evaluation, investigator and patient global assessment, dynamic optical coherence tomography (D-OCT) and reflectance confocal microscopy (RCM). RESULTS Studies subjects presented a statistically significant improvement in global assessment scale (GAS) scores at 14 days (GAS = 1.7 ± 0.6), 1 month (GAS = 1.4 ± 0.7) and at 3 months (GAS = 1±0.7) versus the GAS score obtained before treatment (1.9 ± 0.5) (p < 0.0001). From the Italian study at 6 months (n = 30) 76% of the patients had an improvement in their nail appearance. Reduction in nail plate roughness with improved nail resistance and decreased distal breakage were the most evident benefits, demonstrated on clinical and instrumental evaluations. No side effects were reported. All patients reported an improvement in nail appearance after using the product for 1 month, 3 months and 6 months, and had a positive opinion on the product. CONCLUSIONS This new product is an effective, safe, and easy-to-use option for topical treatment of brittle nails and primary nail fragility and an adjuvant therapy in secondary nail fragility. Moreover, its ease of application and cosmetic qualities allow good compliance. FUNDING ISDIN.

Trachyonychia: a retrospective study of 122 patients in a period of 30 years. J Eur Acad Dermatol Venereol 2020; 34:880-884. [PMID: 31923322 DOI: 10.1111/jdv.16186] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 12/17/2019] [Indexed: 02/03/2023]
Abstract
BACKGROUND Trachyonychia is a nail disease characterized by longitudinal striations, ridges, fissures and/or pitting. This condition can be both idiopathic and associated with other dermatologic diseases. OBJECTIVE AND METHODS The aim of this retrospective study was to analyse the clinical features, onychoscopy, therapy efficacy and outcome of 122 patients with trachyonychia visited at the Hair Disease Outpatient Consultations of the Dermatology Unit of the Department of Experimental, Diagnostic and Specialty Medicine of the University of Bologna, from 1988 to 2018. RESULTS Opaque trachyonychia was the most observed type while shiny trachyonychia, less common, was present especially in milder cases. Pitting was the most frequently observed feature (80.3%), followed by koilonychia (45%) and hyperkeratosis (19.6%). Nail matrix longitudinal biopsy was performed for diagnosis confirmation in 29 cases, and spongiotic was the most common pattern. Topical therapy was prescribed in 109 patients while systemic treatments were reserved for severe cases (38 patients); 22 patients did not receive any treatment. A marked improvement in the appearance of the nails or even a total resolution was seen in 63 patients. CONCLUSIONS Trachyonychia can occur at any age but is more frequent in children and often associated with alopecia areata. The pathological diagnosis of trachyonychia is not mandatory as the disease has generally a benign outcome. Considering the absence of pain and the high rate of spontaneous resolution, treatment is often prescribed only for cosmetic reasons or reserved for severe cases.

Abstract
Oral (OP) and nail (NP) pigmentations may occur simultaneously in physiological or pathological conditions, and may be a sign of underlying syndromic conditions that necessitate further investigation and treatment. Interestingly, the nail unit and oral cavity show a clinical parallelism that may help the clinician to conduct a correct examination and reach a prompt diagnosis. Both OP and NP can manifest clinically with focal or diffuse involvement and are due to external factors (exogenous pigmentation, drug-induced pigmentation) or endogenous factors (racial pigmentation, post-inflammatory pigmentation, nevi, genetic conditions and other disorders). The most concerning differential diagnosis is melanoma. Here we report the pathogenetic basis of OP and NP, together with the description of similar clinical features. To the best of our knowledge this is the first paper to summarize and describe the causes of pigmentation of both the oral cavity and the nail unit.

Markers of microbial exposure lower the incidence of atopic dermatitis. Allergy 2020; 75:104-115.

Abstract
BACKGROUND The hygiene hypothesis proposes that reduced exposure to infectious agents in early life would explain the increase of allergic and autoimmune diseases observed over the past decades in high-income countries. METHODS We conducted a matched case-control study on incident atopic dermatitis (AD). Cases were 426 outpatient children with a first diagnosis of incident AD. Controls were 426 children attending a pediatric/dermatological visit for nonatopic disorders matched to cases (1:1). Particular attention was paid to the time elapsed between the markers of microbial exposure and disease onset, and we considered for controls the same time window of exposures from birth as his/her matched case. Odds ratios (ORs) were computed using multivariable conditional logistic regression models, according to center, sex, age, and period of enrollment, and including as potential confounders a family history of any allergy in parents, type of delivery, having siblings, keeping pets, age at weaning, and having had ≥4 infections. RESULTS The OR of AD first occurrence was 0.35 (P-value = .039) for children who had experienced ≥4 infections compared with those with no infections. A decreasing trend in risk was observed with increasing number of siblings (P-value = .023), the protective effect reaching about 40% for children with 2 or more siblings (OR = 0.62; P-value = .048). Pet keeping, in particular daily contact with dogs, was inversely associated with AD risk (OR = 0.40; P-value = .004). CONCLUSIONS These results support the hygiene hypothesis in its broad sense. Early-life environmental exposures, including pathogens and commensals, act as "microbes contact carriers" influencing immune system balance early in life.

Abstract
BACKGROUND Onychomycosis is the most common nail disease and can affect both fingernails and toenails. When possible, topical treatment is generally preferred both by patients and physicians because it is associated with lower risk of systemic side effects and drug interactions than oral antifungals, avoiding laboratory monitoring. OBJECTIVE The aim of our study was to evaluate the efficacy, tolerability, and patient's compliance of a new topical antifungal containing vitamin E and essential oils of lime, oregano, and tea tree. PATIENTS AND METHODS We enrolled 20 patients with mild-moderate distal subungual onychomycosis due to dermatophytes or non-dermatophyte molds. The product was applied once daily on the periungual tissues and on the nail plate for 6 months. Follow-up without therapy continued for another 6 months in order to evaluate the product's effect maintenance. Periodic evaluation of treatment efficacy was performed by standardized photography and mycological examination (KOH + culture) of the target nail at baseline (T0), after 3 months (T1) and 6 months (T2) of therapy, and after 6 months of follow-up (T3). RESULTS At the end of the 12-month study, the majority of patients achieved a complete cure of onychomycosis (78.5%). All patients were very satisfied by the treatment. No side effects were recorded. CONCLUSIONS The results of our study indicate that this new topical antifungal containing vitamin E and essential oils of lime, oregano, and tea tree is an effective and safe option for topical therapy of onychomycosis. This topical antifungal nail oil restructures the nail appearance, improving patient's adherence to therapy and reducing the risk of relapses, maintaining results over time.

Abstract
We present a unique patient with erosive pustular dermatosis of the scalp (EPDS) with several unique features: (1) a rare case of EPDS occurring after herpes zoster (HZ) infection and (2) the first reported case of recurrence of HZ induced by topical immunosuppressive therapy (clobetasol 0.05% cream and tacrolimus 0.01% cream) in a patient with underlying EPDS. Based on our patient, we recommend to exercise caution with the prolonged use of potent topical steroids in areas previously affected by herpes zoster.

Abstract
Nail diseases are rarely given significant importance in general consultation and their specific examination is often neglected, while localization to the nails could be an initial sign of a syndrome or a systemic disorder. Although rarely, nail alterations could be a sign of a systemic disorder, in which a prompt observation is crucial for an early diagnosis. We describe the case of an elderly woman with a long history of nail dystrophy, previously labelled as nail fragility. On enquiry, similar nail changes were discovered to have affected the patient's son, who was visited the following week. Diagnosis of the Nail-Patella Syndrome (NPS) was suspected on the basis of nail alterations in both patients and confirmed by complementary radiographic examination. Screening for severe renal complications, which could have negatively affected the prognosis and have led to end-stage renal disease, followed. The prompt diagnosis of NPS and the associated diseases are mandatory for a correct management of these patients.

Abstract
BACKGROUND/OBJECTIVES Lichen striatus is a unilateral inflammatory dermatosis that rarely affects the nail unit. When the inflammation involves the nail unit, classic lichenoid nail changes are easily detectable, more often limited to only one portion of the nail. Usually the nail dystrophy coexists with periungual skin papules following Blaschko's lines, but it could also be an isolated feature. Because a nail unit biopsy presents difficulties in execution, especially in a child, the aim of our study has been to describe the nail unit dermoscopy features of lichen striatus hoping to provide a valid aid to clinicians in the diagnosing this rare disorder. METHODS We reviewed the images of five pediatric patients with a clinical diagnosis of lichen striatus. Data about sex, age, localization, predisposing/triggering factors, and associated disorders are reported. RESULTS The diagnosis of lichen striatus can be challenging as there are clinically overlapping features with related dermatoses. A common diagnostic pitfall occurs with inflammatory linear verrucous epidermal nevus and lichen planus. Involvement of only one part of the nail plate with linear longitudinal fissuring, ridging, and distal splitting, especially if seen with perionychial skin lesions, is characteristic of lichen striatus. CONCLUSIONS Nail lichen striatus is rare, and there is sparse published literature on it. When the changes in lichen striatus are limited to the nail, the diagnosis may easily be missed. We therefore believe that dermoscopy is an important diagnostic maneuver, which should be integrated into the evaluation of patients with potential lichen striatus, and in particular is helpful for clinicians unwilling or unable to perform a nail unit biopsy.

Abstract
Background Alopecia areata is a nonscarring hair loss that usually causes round patches of baldness, but alopecia areata incognita (AAI) and diffuse alopecia areata (DAA) can cause a diffuse and acute pattern of hair loss. Objective To analyze the clinical, trichoscopic, histological, and therapeutic features of AAI and DAA. Methods The study was designed to include data of patients with histological diagnosis of AAI and DAA enrolled in our Hair Disease Outpatient Consultations. Results DAA had a greater involvement of the parietal and anterior-temporal regions, while AAI manifested itself mainly in the occipital-parietal regions. The most frequent pattern was empty yellow dots, yellow dots with vellus hairs, and small hair in regrowth, but the presence of pigtail hair was found almost exclusively in those with AAI. In cases of DDA, the finding of dystrophic hair and black dots was more frequent. The most frequent trichoscopic sign in both diseases was the presence of empty yellow dots, which, however, were described in a higher percentage in cases of DAA. The diseases have a benign course and are responsive to topical steroid therapy. Conclusions Trichoscopy is very important for the differential diagnosis between the 2 diseases and to select the best site for biopsy. In the presence of diffuse hair thinning, these entities must be considered.

Abstract
Background Nail changes are a common side effect of taxane chemotherapy, although their correct management is poorly standardized. Objective To evaluate incidence, clinical aspects, and response to treatment of taxane-induced nail side effects in patients treated with taxanes for malignancies. Patients and Methods We performed a retrospective clinical study of 79 patients with taxane-induced nail changes from January 2015 to July 2018. Results Paclitaxel was the most responsible drug and both hands and feet were often affected (46.8%). Grade 2 nail toxicity was seen in 63.3% of the patients, including painful subungual hematoma, hemorrhagic onycholysis, and paronychia. Grade 3 nail toxicity was seen only in 2.5% of the patients, including hemorrhagic onycholysis and pyogenic granuloma. Removal of the detached nail plate with application of topical antibiotics and steroids induced regression of symptoms within 2 weeks. Conclusions Nail toxicity develops mostly at the end of therapy, and total drug dosage is the only known factor that predisposes to these side effects. Trauma possibly plays a role as the most severe signs are located on the great toenails. Although it is impossible to prevent taxane-induced nail side effects, a careful patient monitoring permits to immediately recognize and manage the symptoms in order to induce their remission and improvement of the patient's quality of life.

Abstract
Alopecia areata (AA) is an organ-specific autoimmune disorder that targets anagen phase hair follicles. The course is unpredictable and current available treatments have variable efficacy. Nowadays, there is relatively little evidence on treatment of AA from well-designed clinical trials. Moreover, none of the treatments or devices commonly used to treat AA are specifically approved by the Food and Drug Administration. The Italian Study Group for Cutaneous Annexial Disease of the Italian Society of dermatology proposes these Italian guidelines for diagnosis and treatment of Alopecia Areata deeming useful for the daily management of the disease. This article summarizes evidence-based treatment associated with expert-based recommendations.

Abstract
Erosive pustular dermatosis of the scalp is a rare chronic inflammatory disorder defined. It usually affects elderly people and is characterized by extensive pustular lesions, erosions, and crusts located on the scalp. The pathogenesis of this disease is not completely understood, but a known predisposing factor is skin trauma. Autoimmune disorders including rheumatoid arthritis, autoimmune hepatitis, Hashimoto thyroiditis, and Takayasu aortitis are associated diseases reported. The clinical examination reveals erythema, erosions, crusts, follicular pustules, and in advanced stages, scarring alopecia. A scalp biopsy is recommended but not specific, founding epidermal atrophy, focal erosions, and a mixed inflammatory infiltrate consisting of neutrophils, lymphocytes, and plasma cells. Bacterial cultures, fungal and viral stains are not necessary and are usually negative. . Topical high-potency corticosteroids, retinoids, calcipotriol, dapsone, and topical tacrolimus are reported treatments, while photodynamic therapy has been effective in some patients, but has induced the disease in others. All the findings are suggestive but not specific, so it is an excluding diagnosis. The combination of predisposing factors is very important for a correct diagnosis, such as elderly age, sun-damaged skin, presence of androgenetic alopecia, together with clinical manifestations, non-specific histology and laboratory investigations negative for other disease. In our opinion, this scalp disease is a challenge for the dermatologist. We review all the literature to better define the possible solutions in case of suspected erosive pustular dermatosis of the scalp.

Abstract
Scalp sarcoidosis is generally uncommon and it may present itself with varying morphologies; therefore, it is important to differentiate this disease from other forms of cicatricial and non-cicatricial causes of alopecia. Trichoscopy and histopathology are essential to rule out other skin diseases and to confirm diagnosis. Treatment options include topical, oral, and intralesional corticosteroids; immunosuppressive agents; and hydroxychloroquine, in order to arrest the progression of alopecia. Here, the authors present a case of scalp sarcoidosis with systemic involvement, in which dermoscopy gives important clues for its diagnosis. The authors have also reviewed the literature and identified 46 cases of sarcoidosis that induced alopecia.

Abstract
BACKGROUND Nail dermoscopy (onychoscopy) during physical examination assists in correct diagnosis. Often further magnifications are necessary for an effective differential diagnosis. With the addition of a red light to the dermoscope, important vascular features can be visualized. OBJECTIVE To describe common features observed at onychoscopy with a new device that combines the regular white light with the red light illumination, demonstrating that it is useful for diagnosis of nail disorders. METHODS We enrolled 33 consecutive patients referred to the Nail Diseases Dermatology Unit of the University of Modena and Reggio Emilia and to the Outpatient Consultation for Nail Disease of the Dermatology Unit of the University of Bologna. Patients were assessed with a standard hand-held dermoscope and at the red light dermoscope. Dermoscopic images were collected. RESULTS The new prototype was used during daily clinical practice and allowed a more accurate visualization of some details that classic onychoscopy can miss. In particular, with the help of the red light it was possible to better visualize nail lesions that were characterized by some kind of colour change or vascular alterations. CONCLUSION The new device of red light for vascular pattern onychoscopy can be a new investigation method to observe nail alterations, especially due to vascular pattern, even with low magnification, without the necessity to use higher resolutions.

Abstract
Nail psoriasis affects 50-79% of patients with skin psoriasis and up to 80% of patients with psoriatic arthritis, and can also represent a negative prognostic factor in individuals with plaque psoriasis. Treatments for nail psoriasis are limited, as nails are often difficult to treat with topical therapies alone, and relapse is common. Among different systemic agents, secukinumab, a fully human monoclonal antibody targeting interleukin (IL)-17A, is the only antibody supported by a trial specifically conducted in patients with nail psoriasis (the TRANSFIGURE trial) and has the longest follow-up available to date. In this setting, secukinumab is characterized by the highest efficacy at week 16. This review analysed the different therapeutic options for nail psoriasis, focusing on new treatments that have shown promising results in this field.

Abstract
Nail involvement in psoriasis is common, and the severity of it does not always parallel the intensity of cutaneous disease. We created a consensus group, of which the aim was to provide practical recommendations for the treatment of nail psoriasis in patients without skin psoriasis or with mild skin lesions with no indication for a systemic treatment. This collaborative process was conducted by an international panel of dermatologists with special expertise in nail disorders, using formal consensus methods. During this process, the panel strived to establish an agreement regarding the definition of nail psoriasis, the severity of nail psoriasis, and treatment response. Treatment recommendations are provided regarding nail psoriasis severity and matrix or bed involvement. Few-nail disease was considered as nail psoriasis affecting ≤3 nails. In the case of matrix involvement only, intralesional steroid injections were considered the treatment of choice. Topical steroids alone or in combination with topical vitamin D analogues were suggested for nail psoriasis limited to the nail bed. For the systemic treatment of nail psoriasis acitretin, methotrexate, cyclosporine, small molecules, and biologics may be employed.

Abstract
The term melanonychia describes a black-brown-gray pigmentation of the nail plate that, in most cases, appears as a longitudinal band. Melanonychia can be observed at any age, affecting one digit or several digits, in both fingernails and toenails. Its causes can be difficult to differentiate clinically and depend on the number of bands and on their color, edge, and width. For this reason, especially in adults and when the pigmentation is localized in one single digit, biopsy and histopathological examination still represent the gold standard for a definitive diagnosis. Dermoscopy should be used routinely in the evaluation of a pigmented nail, as it provides important information for the management of melanonychia and can help avoid unnecessary nail biopsies. In cases of melanonychia it is important to establish whether the pigment is melanin or not and to determine whether the pigmentation of melanin is due to activation or proliferation and whether it is benign or malignant.

Abstract
Background: Treatment of alopecia areata (AA) involves use of high potency topical corticosteroids under occlusion that, even very effective, can lead to several adverse effects. Objective: We report 10 cases of patients with AA that, after using high potency topical corticosteroids, have developed tinea versicolor of the neck area. Methods: Ten patients with AA, aged 18-38 years, were prescribed with clobetasone propionate 0.05% cream under occlusion every other day but, after 3-4 months of treatment, they returned to our facility complaining the appearance of multiple white or red-brown round or oval macules in the neck area. Results: Diagnosis of pityriasis versicolor was confirmed by direct microscopy examination of skin scrapings in 10% potassion hydroxide (KOH) solution. All patients received systemic antifungal therapy associated with the daily use of ketoconazole shampoo. Conclusion: Tinea versicolor of the neck should be included among a rare but possible side effect of prolonged application of high potency topical steroids on the scalp. These cases reinforce the importance of careful dermatologic examination and recommend preventive measures in patients with alopecia areata that are using these drugs.
