[Cavitary lung cancer with a fungus ball-like shadow].
A 75-year-old woman had an irregularly shaped cavitary lesion in the right upper lung field on a chest X-ray film and a CT scan. Primary lung cancer was suspected, but no evidence of malignancy or of infection was found on examination of specimens obtained by transbronchial biopsy and by lavage. Seven months after the first examination the cavity was found to have enlarged and an intra-cavitary fungus ball like shadow was seen. On the basis of these findings, pulmonary aspergilloma with or without primary lung cancer was suspected. Examination of a specimen obtained by transbronchial biopsy revealed squamous cell carcinoma. Right upper lobectomy was done, and the resected tissue included a polypoid nodule and a cavity wall composed of a milky-white solid tumor. Microscopic examination revealed a moderately differentiated squamous cell carcinoma in both the cavity wall and the polypoid nodule, and no evidence of fungal involvement.
