Male breast cancer with mandibular metastasis. A case report

Abstract

Female breast cancer is one of the major causes of death among women while male breast cancer is relatively uncommon and accounts for about 1% of all breast cancers in both sexes. Influencing factors are: gynecomasty, familiarity for male breast cancer, Jewish and African-American male population. From the histological point of view, it is not different from the female breast cancer, except for the infiltrant ductal carcinoma, but with a much severe prognosis. Breast cancer metastases to the jaws are rare, only 1%; the most common sites of metastases are: lungs(59-69%), liver (58-65%), bone (44-71%), pleura (23-37%), brain (9-22%) and kidney (4-17%). At present, based on a literature research (May 2006), there have been just two other case reports of male breast cancer metastasis to the maxillofacial region, both to the mandible. The case of a 69-year-old white man who in 2001 underwent a radical mastectomy due to ductal breast cancer is reported. In 2005 the patient was referred to our department by his oncologist for multiple oral fistula. A mandibular TC revealed osteolytic lesions and the patient underwent mandibular surgery to remove the lesions and clean up the area. The histological examination was consistent with that of a metastatic deposit of adenocarcinoma of the breast. In June 2006 the patient died due to worsening of the general clinical conditions, in particular due to ascites and hepatic insufficiency.
