[Cavitary pulmonary metastasis from bladder cancer: a case report].
A 69 year-old [correction of 63] man who had had a radical cystectomy for bladder cancer was admitted to our hospital because of hemosputum and right femoral pain. His chest radiograph and computed tomogram showed a mass shadow with a cavity in the left upper lung field. Sputum cytology showed class V squamous cell carcinoma and a bone scintigram showed right femoral metastasis. Despite radiotherapy to the left upper lung and the right femur, the patient's condition worsened, and he died of respiratory failure after hospitalization for about 1 month. At autopsy, pathologic studies of lung cancer revealed mixed-type transitional cell carcinoma, squamous cell carcinoma and adenocarcinoma. A diagnosis of metastatic lung cancer from bladder cancer was made. Cavitating pulmonary metastasis is uncommon. We report a rare case of pulmonary metastasis from bladder cancer, with mixed-type histopathology at both primary and metastatic sites.
