Mycoses 37: ) : A Case of Pulmonary Chromomycosis Caused by Exophiala dermatitidis Chiyoko Tanamachi, Kouji Hashimoto, Kazunori Nakata, Kimitaka Sagawa Department of Laboratory Medicine, Kurume University Hospital We report a rare case of pulmonary mycosis involving E. dermatitidis. The subject was a 53-year-old woman with a history of bronchiectasis whose primary complaints at the time of hospitalization were yellowish phlegm and anterior chest pain. Chest X-rays and chest CT images revealed a shadow in the lower right lung field, and pulmonary mycosis was suspected. Grocott staining of samples from the patient s bronchial lavage fluid showed many yeast-like fungi. When coughed up sputum and bronchial lavage fluid were cultured at 35, colonies formed which appeared to be black yeast. However, when cultured at 27 filamentous colonies formed, so we confirmed a diagnosis of the dimorphic black yeast Exophiala dermatitidis. After initial treatment with miconazole, combined treatment with itrazonazole and flucytosine proved e#ective. 30 Vol. 18 No
