White piedra (or tinea blanca) is a mycosis of the hair [1] caused by several species of fungi in the genus Trichosporon. It is characterized by soft nodules composed of yeast cells and arthroconidia that encompass hair shafts.
White piedra is asymptomatic. [2] [3] [4]
White piedra is caused by Trichosporon beigelii. [5] [6] White piedra can occur on the hair of the scalp; Trichosporon ovoides is likely the cause in this case. [7] White piedra on scalp hair is rarely caused by Trichosporon inkin; pubic hair with white piedra is what T. inkin is mainly associated with. [8] White piedra can occur on pubic hair; T. inkin likely causes this. [7]
Trichosporon mucoides can also cause white piedra. [2] In such cases, a periodic acid-Schiff–diastase stain and fungal culture may aid in diagnosis. [2]
There are several approaches to treat this infectious disease. One approach involves shaving the affected areas. Another approach involves the use of antifungal medication, such as ketaconazole shampoo. [2] [9]
