SANTACRUZ IBARRA, Jorge Javier; GUACA-GONZALEZ, Yina Marcela  and  MONCAYO-ORTIZ, José Ignacio. Report of cases of white stone in patients of dermatological centers from Pereira. Revista médica Risaralda [online]. 2017, vol.23, n.1, pp.48-50. ISSN 0122-0667.

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
