title: Recurrent malignant fibrous histiocytoma in psoas muscle: a case report.
abstract: Malignant fibrous histiocytoma is one of the most common sarcomas that occur in soft tissue, it usually develops in old age individuals and the incidence is similar between the genders. We report here on a case with invasive local recurrence after surgical resection of a malignant fibrous histiocytoma that occurred in the left psoas muscle of a 69-year-old male patient. The patient was first admitted to our hospital with a primary lesion in the left lower abdomen, as seen on magnetic resonance imaging. We report here on a rare case of a malignant fibrous histicytoma in the psoas muscle.
