Peritoneal dissemination from malignant fibrous histiocytoma of the buttock: unusual metastases from a rare tumor.
We report a case of malignant fibrous histiocytoma (MFH) of the right buttock with multiple metastases to the lung, bone, and small intestine. He received resection and end-to-end anastomosis of the jejunum for the jejunal metastatic tumor, and mass excision of the metastatic tumor of the left femur followed by closed reduction and internal fixation and palliative radiotherapy. In addition, he received palliative radiotherapy to the metastatic pulmonary tumor with suspicious invasion into the thoracic aorta. However, one month after the completion of the aggressive local treatments, metastatic tumors recurred in the abdominal cavity, an extremely unusual site, resulting in peritoneal dissemination. He died of progressive disease 5 months after the initial diagnosis.
