摘要

导言：Cutaneotrichosporon debeurmannianum 是一种常见于热带地区的酵母样无定形稀有真菌。本病例报告是南美洲的第一份病例报告。病例报告一名 67 岁的患者因 5 年前在海上受到足部创伤而导致右足疼痛，至今已有 5 年病史。在手术探查过程中，发现了一个令人印象深刻的白色脑形囊肿。利用基因 ITS1、ITS4、LSU-R 和 LSU-F 进行了遗传分析，并通过系统发生树确定了 C. debeurmannianum。

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

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.
