A unique presentation of subcutaneous Cutaneotrichosporon debeurmannianum infection: A case report of a diagnostic challenge

Abstract

Introduction

Cutaneotrichosporon debeurmannianum is a yeast-like anamorphic rare fungus commonly found in tropical areas. This case report is the first one located in South America.

Case report

A 67-year-old patient presented with a 5-year history of right foot pain attributed to foot trauma while at sea 5 years prior. During surgical exploration, an impressive whitish cerebriform-like cyst was encountered. Genetic analysis using the genes ITS1, ITS4, LSU-R, and LSU-F was performed, and a phylogenetic tree identified C. debeurmannianum.

Conclusion

A complete characterization of this fungus which causes human disease has not yet been achieved and more research is needed.
