MORALES CARDONA, Camilo Andrés; JAIMES RAMIREZ, Ángel Omar; VARGAS HORTUA, Celmira  and  TEJADA FIGUEROA, Constanza. Black piedra and white piedra: Differential aspects. Infect. [online]. 2013, vol.17, n.2, pp.106-110. ISSN 0123-9392.

Black piedra and white piedra are common superficial and asymptomatic fungal infections in tropical countries, characterized by the presence of hard nodules located along the hair shaft. However, in recent years literature on this topic has been limited and the current taxonomy of their etiologic agents is poorly understood. Here we report two cases of black piedra and white piedra in two immune competent Colombian women with numerous nodular lesions in their hair who visited a national reference center in Bogota, Colombia. Despite having been described and classified from a clinical and microbiological perspective more than 100 years ago, little is still known about the history, ecology, mode of transmission, epidemiology and clinical presentation of piedras. Nevertheless, the differences between the two mycoses help to orient clinical and fungal diagnoses.

Keywords : Black piedra; White piedra; Scalp; Trichosporon.
