Abstract
- Malignant fibrous histiocytoma (MFH) is a soft-tissue sarcoma that usually occurs in middle-aged or elderly patients, has a similar male-to-female ratio, and rarely develops in the retroperitoneum, especially in the psoas muscles. The lower extremity is the most common site of origin, followed by upper extremity, the trunk, and the retroperitoneum. Primary retroperitoneal involvement of a malignant fibrous histiocytoma is often diagnosed at an advanced stage as it has no specific symptoms. Primary retroperitoneal involvement of a malignant fibrous histiocytoma is very rare and there is no case report of MFH in the psoas muscle in Korea, as introduced here.
