title: Retroperitoneal malignant fibrous histiocytoma.
abstract: Authors review the case history and follow-up a rare malignant fibrous histiocytoma patient, based on the relevant literary data. The tumor filled the retroperitoneum on the right side, in front of the right kidney. Intravenous urography and computer tomography revealed a 10 x 15 cm sized mass, suspect of being a kidney tumor. Upon surgery, the tumor was found to be a retroperitoneal malignant fibrous histiocytoma. In connection to the case, a brief review is given of the storiform type of malignant fibrous histiocytoma, regarding its etiological, clinical and pathological aspects, the difficulties in diagnosis, as well as the therapeutic possibilities. Authors regard their case worthy of publication because of the retroperitoneal location and significant size of the tumor, and because of the unproven diagnosis prior to surgery. Even after 4 years the patient is symptom- and complaint-free, and CT has revealed no metastases.
