Primary Retroperitoneal Malignant Fibrous Histiocytoma / 대한비뇨기과학회지

ABSTRACT

A malignant fibrous histiocytoma is a rare pleomorphic tumor of the soft tissues. Primary retroperitoneal involvement of a malignant fibrous histiocytoma is very rare and often diagnosed in an advanced stage as it has no specific symptoms. Herein, a case of a malignant fibrous histiocytoma involving the retroperitoneum is reported, which was incidentally found in a 74-year-old male, who complained of pain in the right abdomen and thigh.
