[Pleomorphic carcinoma of the lung rapidly developed multiple metastases after surgery].
Pleomorphic carcinoma of the lung is a type of carcinoma with spindle and/or giant cells with a poor diagnosis. A 73-year-old male was referred to our hospital because of the pulmonary tumor. Lung biopsy revealed that the tumor was poorly differentiated adenocarcinoma. No distant metastasis were observed by systemic examination. A right middle lobectomy with partial resection of the right upper lobe and lymph node dissection were performed, because the tumor (5.3 x 4.0 x 4.0 cm) was located in peripheral S' and invaded S3 via the interlobular space. Histological findings showed adenocarcinoma comprised of spindle cell components that reacted positively to epithelial membrane antigen (EMA) and no lymph node metastasis. Therefore, he was diagnosed with pleomorphic carcinoma of the lung, pT2N0M0, stage IB. But metastatic lesions newly appeared in the thoracic skin, the liver, the diaphragm, the bilateral adrenal glands, and the retroperitoneal space on the 30th postoperative day. He died of peritonitis and pleuritis on only 60 days after the operation.
