Trichosporon beigelii is widely distributed in nature and is classically associated with white piedra, a mycosis that may involve the hair of the human body. Intramammary infections caused by T beigelii may be fatal in cows; the prevalence in affected dairy herds may be high. Affected cows may have hyperthermia, swelling of the udder, and substantially decreased milk production or agalactia. Intramammary infections caused by yeast, including T beigelii, may also be associated with high bacterial counts in bulk-tank milk.

First report of white piedra caused by Cutaneotrichosporon debeurmannianum.
Rev Inst Med Trop Sao Paulo
October 2024
Universidade de São Paulo, Faculdade de Medicina, Instituto de Medicina Tropical de São Paulo, Laboratório de Imunologia e Micologia (LIM-53), São Paulo, São Paulo, Brazil.
Article Synopsis
- Piedras are small nodules found on hair shafts, with white piedra previously linked to Trichosporon beigelii, now causing a reassessment of its causative agents.
- The first recorded case of white piedra was identified as being caused by Cutaneotrichosporon debeurmannianum, which was studied using scanning electron microscopy and cultures from Sabouraud medium.
- Genetic analysis showed 99.6% similarity between the nucleotide sequences of the isolated fungus and the 28S large ribosomal unit rDNA, confirming Cutaneotrichosporon debeurmannianum as the causative agent of this white piedra case.

Objective: This study aimed to describe the clinical presentation, microbiological profile and management of complications of bone wax usage for surgical procedures at the skull base.
Method: The case records of a series of five patients who developed post-operative surgical site complications because of bone wax usage during skull base surgery were reviewed.
Results: In all five patients, persistent site-specific clinical features were noted along with intra-operative presence of excessive bone wax.
