Abstract

Six male patients with breast cancer experienced in the past 38 years were reviewed clinicopathologically. In terms of clinical background, most of the patients were in their 70’s. The mean age was 68. All patients complained of a nodule in the breast, the majority of which were located in the subareolar region. The size of all nodules was under 3.0cm in diameter. Only one patient had heredodiathesis of familial breast cancer. In terms of pathohistological findings all cancers had infiltrated into the surrounding fat tissues of the mammary gland and two of them into the overlaying skin. The histological types of the cancers consisted of three papillotubular carcinoma, two scirrhous carcinoma and one solid-tubular carcinoma. Two of them involved the axillary lymph nodes. Three cancers examined for estrogen receptor and progesteron receptor were all positive. One of two cancers examined for human epidermal growth factor receptor 2 was negative and the other was positive, but fluorescence in situ hybridization was negative.<br>There was a tendency for the age and clinical history of male patients with beast cancer to be more higher and longer, respectively, compared with female patients. Information about male breast cancer should be disseminated more widely.
