DINIZ, Lucia Martins and SOUZA FILHO, João Basilio de. Study on 15 cases of white piedra in Grande Vitória (Espírito Santo - Brazil) over a five-year period. An. Bras. Dermatol. [online]. 2005, vol.80, n.1, pp.49-52. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962005000100007.
White Piedra is a rare fungal infection of the hair shaft, caused by a yeast-like fungus (Trichosporon beigelii), characterized by yellow nodules on the pubic hair, moustache, beard and hair on the axillae and scalp. The objective was to register the presence of 15 cases of White Piedra in Espírito Santo diagnosed at the Dermatology Service in Vitória, over five years. All patients were female with nodules in the scalp hair, 13 were of mixed race and ten were between two and six years old. The hot and humid climate of the region together with the patients' habits regarding use of conditioning creams favored the infection. Moistening the hair with water can facilitate visualization of the nodules.
