Trichoscopic Evaluation of Tinea Capitis.

Tinea capitis is a widespread fungal infection that is even more common in rural areas of the world predominantly among children. The diagnosis of the infection and the identification of the responsible dermatophyte are determined by potassium hydroxide mount microscopy, Wood's lamp examination and mycological culture of the skin scrapings and hair samples. Nevertheless, this conventional setting has several limitations such as lack of availability, low sensitivity and specifity, and particularly prolonged turnaround time for fungal culture. Trichoscopy is a well-proven practical and beneficial aid to faciliate the diagnosis of scalp and hair disorders. Studies performed during the last 15 years revealed several characteristic trichoscopic findings of non-inflammatory tinea capitis namely comma hairs, corkscrew hairs, Morse code-like hairs and zigzag hairs. Thereby, trichoscopy has proved itself in the establishment of prompt diagnosis of TC, identification of the responsible fungus enabling to appropiate treatment on time, and evaluating treatment response by screening the clearance of the trichoscopic features.
