title: [Pulmonary pleomorphic carcinoma].
abstract: Pleomorphic carcinoma is a rare primary pulmonary malignancy. We report 2 surgical cases of pulmonary pleomorphic carcinoma. The first case was a 71-year-old male. Chest computed tomography (CT) showed a rapidly growing tumor with irregular density. Transbronchial lung biopsy revealed the tumor to be malignant. Left lower lobectomy was performed. Pathological diagnosis was pleomorphic carcinoma (pT2N2M0, stage IIIA). He died 8 months after surgery due to brain metastasis and mediastinal lymph node metastasis. The second case was a 74-year-old male who complained of bloody sputum. Chest CT showed a tumor with cavity in the right middle lobe. Brushing cytology under bronchofiberscopy revealed atypical cell. Right middle lobectomy and partial resection of the right lower lobe were performed. Pathological diagnosis was also pleomorphic carcinoma (pT2N0M0, stage IB). He has no findings of recurrence nor metastasis 15 months after the operation.
