Pulmonary Chromomycosis Caused by <i>Exophiala phaeomuriformis</i> in a Patient with a Typical Pulmonary Carcinoid Tumor
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 S<sub>7</sub> 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.
