Abstract

Exophiala spp. cause dematiaceous mycoses, but rarely infect human lungs. A 61-year-old man presented with bloody black sputum. Chest computed tomography showed consolidation in the truncus intermedius and peripheral bronchus, and a mass shadow in the S₇ region of the right lung. Bronchoscopy revealed a protruding black lesion in the bronchial orifice of the truncus intermedius, and Exophiala phaeomuriformis was isolated. The consolidation resolved spontaneously, and the residual tumor was diagnosed as a carcinoid tumor. This case highlights the fact that pulmonary chromomycosis may occur in immunocompetent individuals without any preexisting structural changes in the airways.

典型肺类癌患者由嗜霞光外孢子虫引起的肺色霉菌病1例。

外菌属引起真菌病，但很少感染人的肺部。一名61岁男性，有黑色带血痰。胸部电脑断层显示支气管中间干及外周实变，右肺S7区可见肿块影。支气管镜检查发现中间干支气管口有突出的黑色病变，分离出金黄色外孢子虫。实变自行消退，残余肿瘤诊断为类癌。本病例强调了肺色霉菌病可能发生在免疫正常的个体中，而气道中没有任何预先存在的结构改变。
