Tinea of vellus hair: a diagnostic and therapeutic challenge.

Tinea infection is a common superficial fungal infection of the skin, hair and nails. Tinea of vellus hair is a rare form of dermatophytosis that is difficult to diagnose and treat. Herein, the authors report the case of a patient who had an itchy rash on the cheek. Microscopic and mycological studies confirmed the diagnosis of tinea of vellus hair. The patient was treated with systemic antifungal therapy with clinical improvement. This report aims to describe an infrequent subtype of common disease and review clinical clues, tools for diagnosis as well as treatment plans. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
