Malignant fibrous histiocytoma is the commonest soft tissue sarcoma of adults. The soft tissue of the extremities is the commonest primary site of malignant fibrous histiocytoma. It is much less common in the female retroperitoneum, leading to diagnostic errors. The clinical, radiographic and CT signs are non-specific. This tumor can only be diagnosed by histology. An initial complete resection is essential for successful treatment of the primary tumor. Radiation therapy is limited and chemotherapy has only been successful in a limited number of cases. This tumor has a poor prognosis. These lesions are relatively rare and consequently difficult to study. The authors report three cases and review the literature.
