RESUMEN
La piedra blanca es una micosis superficial crónica y asintomática poco frecuente del pelo causada por Trichosporon spp. (T. asahii, T. cutaneum o T. beigelii, T. inkin y T. mucoides), caracterizada por presentar nódulos blandos, blanquecinos, adheridos a los tallos pilosos, preferentemente del cuero cabelludo, axilas, cejas, pestañas y con menor frecuencia, en la barba, el bigote, el pubis y el perineo. Suele aparecer con mayor frecuencia en población de climas templados y tropicales. En los tres casos reportados se tomó muestra de los cabellos con los nódulos sospechosos, se le realizaron pruebas diagnósticas que permitieron confirmar la presencia de estructuras levaduriformes compatibles con Trichosporon spp. La sospecha de pediculosis es el motivo de consulta de los pacientes con piedra blanca, confundiendo los nódulos con liendres; por consiguiente es importante que el médico tenga claro las enfermedades micóticas con las cuales se debe hacer el diagnóstico diferencial para poder orientar y establecer el adecuado tratamiento para el paciente
ABSTRACT
The white stone is a rare, superficial, chronic and asymptomatic mycosis of the hair caused by Trichosporon spp. (T asahii, T. cutaneum or T. beigelli, T. inkin, and T. mucoid), which is characterized by the presence of white soft nodules, adhered to the hair shafts, preferably the scalp, armpits, eyebrows, eyelashes, and less frequently, in the beard, moustache, pubic area and perineum. It usually appears with greater frequency in areas of temperate and tropical climates. In the three reported cases, the sample of hair was taken from suspect hair, and then a series of diagnostic tests were performed to allow the confirmation of the presence of yeast shaped structures compatible with Trichosporon spp. Often, a possible pediculosis was the main reason of consultation of the patients who suffer white stone, and it can be confused with nodules of nits. Therefore, it is important that the physician has a better understanding of the fungal diseases that will be part of the differential diagnosis in order to guide and establish a proper treatment for the patients
