Abstract
White piedra is a superficial, chronic, asymptomatic mycoses caused by yeast fungi of the genus Trichosporon . It affects the hair, especially of the head, less frequently of the pubis, perineum, armpit, beard, mustache, eyebrows and eyelashes, and is characterized by the formation of soft nodules or fungal clusters. It affects all age groups and both sexes, predominantly women. Diagnosis is made by direct examination of the affected hair and culture on Sabouraud dextrose agar. The identification of species occurs through more specific identification procedures, such as mass spectrometry (MALDI-TOF) and PCR). The objective of this work is to report two cases of familial white piedra caused by T. inkin identified by PCR.
