Case of pulmonary pneumocytoma: A probable cytological diagnosis with histopathological confirmation.

Pneumocytoma is a rare benign tumor of the lung that usually presents as a solitary pulmonary nodule. It is believed to arise from the primitive undifferentiated respiratory epithelium. We report a case of pulmonary pneumocytoma that was suspected on needle aspiration smears and confi rmed histologically. This case describes the cytological features of pneumocytoma that are rarely described in textbooks.
