Malignant fibrous histiocytoma with widespread metastasis and pulmonary cancer.

An autopsy case of malignant fibrous histiocytoma (MFH) with widespread metastases and lung carcinoma in a 64-year-old Japanese woman is reported. The initial signs were cough and sputum, followed by hemosputum. A chest X-ray photo showed a right pleural tumor, which could not be identified from a biopsy specimen, but was identified as MFH by light and electron microscopic studies on biopsy specimens of tongue tumors. Autopsy examination revealed metastases of the MFH to the brain, lung, liver, kidney, adrenal, pancreas, retroperitoneum, and some bones, and pulmonary adenocarcinoma.
