[Pulmonary malignant fibrous histiocytoma treated with cisplatin plus etoposide followed by surgery].
A 47-year-old woman was admitted to our hospital with a mass shadow in the upper lobe of the right lung. Undifferentiated carcinoma was diagnosed after transbronchial biopsy. Combination chemotherapy consisting of cisplatin and etoposide was given. After two cycles of chemotherapy, partial response was obtained, and surgery was done because there was no evidence of lymph node metastasis or distant metastasis. After successful surgery, malignant fibrous histiocytoma was diagnosed because histological examination revealed the typical storiform pattern and most tumor cells showed positive cytoplasmic staining for alpha 1-antitrypsin, alpha 1-antichymotrypsin, and CD68. No evidence of another primary lesion was found, so this tumor was thought to be a pulmonary malignant fibrous histiocytoma. Cisplatin and etoposide have synergistic effect in vivo, and this combination is widely used as a standard regimen for small cell lung cancer and other malignancies. It might also be effective against pulmonary malignant fibrous histiocytoma.
