Abstract

This study analyzes the clinical characteristics of patients diagnosed with White Piedra through a systematic review of cases in the literature. A sample of 131 subjects was considered, of which 91.6% were female and most were 18 years of age or younger. Most studies were conducted in Brazil, followed by India, and Mexico. The most common etiologic agent found was Trichosporon spp (34.3%). Most affected patients were asymptomatic (94.6%) and predisposing factors included long hair, use of a hair band or hair accessories, and wet hair. The most common clinical feature was the presence of nodules. The evaluation of treatment effectiveness was hindered by the scarcity of follow-up information in the majority of the studies. It is concluded that White Piedra infection is more common in young women and is associated with hair-related factors.

Keywords: Trichosporon; White Piedra; hair concretions; hair infection; superficial mycosis.
