Abstract

We present a case of malignant fibrous histiocytoma of the testis in a 59 year- old male who admitted to our hospital with left testicular painless mass presenting for two months. A scrotal ultrasound examination and magnetic resonance imaging revealed a 9 cm left testicular solid mass. Serum tumor markers were unremarkable. The patient underwent left radical orchiectomy. Histopathologic diagnosis was giant cell variant of malignant fibrous histiocytoma which composed of varying amounts of a mixture of spindled, rounded and osteoclastic type giant cells. Hemorrhagic and necrotic areas were seen between tumor nodules. In immunohystochemical staining, vimentin, CD68 were positive and SMA was focally positive. The patient then received adjuvant chemoterapy and currently, he has no sign of recurrence.
