title: [Pleomorphic carcinoma of the lung with idiopathic interstitial pneumonia; report of a case].
abstract: A 69-year-old man was referred to our hospital for further examination of the abnormal shadow on chest radiography. Chest computed tomography (CT) showed a tumor mass, 4 cm in size, in his right lung (S6) and interstitial pneumonia in the surrounding lung parenchyma Bronchoscopic brushing cytology revealed squamous cell carcinoma cells. Right lower and middle lobectomy was performed due to the metastasis to interlober lymph node. Histological findings showed squamous cell carcinoma comprised of spindle cell component, and there were also fibroblastic foci and fibroid thickness in the interstitium. Therefore he was diagnosed as pleomorphic carcinoma and usual interstitial pneumonia (UIP). About 7 months after the operation, the patient died of mainly multiple bone metastases. Pleomorphic carcinoma with UIP is very rare, so we report this case with references to the literatures.
