RESUMO
MALIGNANT FIBROUS HISTIOCYTOMA (MFH) IS A FAIRLY COMMON TUMOR IN THE DEEP SOFT TISSUES: the most frequent primary sites are the lower (49%) and upper (19%) limbs, but it has been reported even in the retroperitoneum and abdomen (16%), while localization in the breast is extremely rare (1-2). Breast cancer is rarely seen in males, accounts for approximately 1% of all breast cancer, and the breast sarcomas constitute less than 1% of breast tumors in both sexes. In the review of the literature, this is the third male and first young male with MFH. Here, we present a 37-years-old male patient who is diagnosed to have malignant fibrous histiocytoma in a variant of pleomorphic fusiform cell localized in the left breast. Following the wide local excision, the patient was given an adjuvant 50 Gy of external radiotherapy. He remained alive and well after 42 months of followup. We believe that reporting such few cases would contribute to forming treatment algorithms of rare tumors.
