Trichosporon inkin: An Uncommon Agent of Scalp White Piedra. Report of Four Cases in Brazilian Children

  • Published:
Mycopathologia Aims and scope Submit manuscript

Abstract

We report four cases of scalp white piedra (SWP) in Brazilian female children. Morphological and physiological approaches gave inconsistent results for identifying Trichosporon to species level, while the sequencing of the intergenic spacer 1 region of ribosomal DNA accurately identified the agent of SWP as T. inkin. These cases emphasize the occurrence of this species causing this type of infection. The molecular identification of the suspected agent is needed for appropriate epidemiological surveillance of superficial mycoses caused by Trichosporon species.
