A Case of Peripheral Epidermoid Carcinoma Showing a Fungus Ball-Like Shadow

A 52-year-old female was admitted to our hospital because of hemoptysis. A chest X-ray showed a cavity in the left middle lung field in which a fungus ball-like material was recognized by tomography and CT. The nodule decreased in size over several days, and the fungus ball-like material also disappeared. We diagnosed the lesion as epidermoid carcinoma based on the microscopic findings of biopsied material. Regarding the macroscopic and microscopic findings of surgical specimen, there was only a small amount of blood clot without any fungus in the cavity. From the patient's history of hemoptysis and the blood clot found in the fungus ball-like shadow removed during the operation, we considered it to have been related to the blood clot and bleeding in the carcinomatous cavity.
