Abstract:  Diagnosis of tinea capitis (TC) can be challenging for dermatologists, especially in noninflammatory TC caused by anthropophilic dermatophytes and in black patients, in whom erythema of the scalp is difficult to appreciate. The finding of a typical TC dermoscopic pattern may lead more quickly to a correct diagnosis.
