INTRODUCTION: Trichilemmomas are a form of benign adnexal neoplasm with differentiation toward the follicular outer sheath. Nevus sebaceous (NS) of Jadassohn is a congenital malformation characterized as a nonhereditary hamartoma of the adnexal structures of the skin, mainly the pilosebaceous unit. NS represents a fertile field for the development of secondary adnexal neoplasms, commonly benign but occasionally malignant. To our knowledge, one case of a pigmented desmoplastic trichilemmoma (DT) has been reported in the English literature...

INTRODUCTION: Localized longitudinal erythronychia is defined as a single nail with a longitudinal red band extending the length of a nail plate. It has a broad differential of benign and malignant etiologies, and is rarely due to benign vascular proliferations. CASE PRESENTATION: We present a unique case of nail unit arteriovenous hemangioma presenting as longitudinal erythronychia of the left thumbnail in a 76-year-old male. The band was 6 mm and encompassed over 40% of the surface area of the nail plate...

INTRODUCTION: Keratoacanthoma (KA) is a group of tumors of epidermal origin with controversial nature. Subungual keratoacanthoma (SUKA) is a rare and destructive variant with more aggressive behavior. SUKA appears as a rapidly growing, painful tumor beneath the nail plate that rapidly progresses to a mass that can measure up to 2 cm. The toe location is unusual. The diagnosis must be made based on the correlation of clinical, radiological, and histopathological findings. CASE PRESENTATION: We present two cases of patients diagnosed with SUKAs with different clinical presentations which ranged from very typical to uncommon one...

REVIEW

Disease severity assessment tools play a large part in evaluating skin conditions in dermatology. Currently, there is no existing validated assessment tool for keratosis pilaris (KP), a benign yet highly prevalent follicular disorder. A range of proposed scoring tools have been used in different clinical trials for the assessment of potential treatments for KP. A literature review of the current scoring systems used for KP shows that there is a lack of consistency with most studies using varying versions of unvalidated investigator global assessment (IGA) scores and quartile grading systems...

INTRODUCTION: Radiation-induced alopecia (RIA) is a side effect resulting from cranial radiation therapy (RT) and it can be temporary or permanent. In cancer patients, RIA is a less frequent event than chemotherapy-induced alopecia, although the former is more likely to cause permanent hair loss. It is characterized initially by intense anagen effluvium caused by acute dose-dependent damage to the matrix cells of anagen follicles. Proton therapy (PT) is a specific type of RT used in the treatment of brain tumors, which sometimes can cause proton-induced alopecia (PIA), a rare subtype of RIA...

INTRODUCTION: Onychomycosis is a common nail disorders. Antifungal resistance, interactions, and side effects limit treatment options. Fractional CO2 (FCO2 ) laser along with topical antifungal is effective in multiple monthly sessions. A modification reducing repeated visits and hence better compliance is preferable. Single-session FCO2 laser following urea occlusion is reported to be effective. Thus, we conducted a study to determine the efficacy of single-session FCO2 laser with 1% terbinafine cream with and without "urea cream occlusion" in managing onychomycosis...

Scalp seborrheic dermatitis (SSD) is a prevalent chronic, relapsing inflammatory skin disease. The etiology is related to sebum production, bacterial proliferation - Staphylococcus sp., Streptococcus , and M. restricta - and host immunity factors - NK1+, CD16+ cells, IL-1, and IL-8. Trichoscopy features include mostly arborizing vessels and yellowish scales. New trichoscopic findings were described to guide the diagnosis as dandelion vascular conglomerate, "cherry blossom" vascular pattern, and intrafollicular oily material...

Hidradenitis suppurativa (HS) often coexists with obesity, metabolic syndrome, diabetes mellitus, or impaired glucose tolerance and insulin resistance and polycystic ovarian syndrome. Metformin is a medication used for the treatment of diabetes, acting in multiple ways. There is evidence that it decreases inflammatory cytokines, some of which are implicated in the pathogenesis of HS (TNF-α, IL-17). We performed a systematic review of data regarding the efficacy and safety of metformin for the treatment of HS...

INTRODUCTION: Antigen presentation and antimicrobial immune responses involve the human leukocyte antigen (HLA) system. Onychomycosis is primarily caused by dermatophytes and affects around 5.5% of the population worldwide. Yet, only limited data exist on the associations between the HLA system and onychomycosis. Thus, the objective of the study was to investigate if there is an association between HLA alleles and onychomycosis. METHODS: Participants in the Danish Blood Donor Study were defined as cases of onychomycosis and controls based on antifungal prescriptions in the national prescription registry...
