MALE BILATERAL BREAST CANCER: CASE REPORT

Introdução

Breast cancer in men bilaterally is extremely rare. Breast cancer represents 1% of all cancers, while bilateral cancer represents 5% of a total number of patients with breast cancer, which may be synchronic or metachronic. Many cases of breast cancer in men are detected between 60 and 70 years, with an average of 67 years of age. In men there is a tendency for late diagnosis at a more advanced stage than in women.

Relato de caso

Patient JSS, 68 years old, from Afogados da Ingazeira-PE, was consulted with breast tumoration, in June 2016. Already arrived at the service with diagnosis of breast cancer through core-biopsy examination. The physical exam presented bulging in the left retroareolar region and in the palpation a hardened tumoration. Radical mastectomy was performed. The histopathological results confirmed an invasive mucinous carcinoma with histological grade I, nuclear grade II and mitotic grade I. Free margins. The most frequent histological type in men is ductal (85-90%), followed by papillary in 4.5% and mucinous 2.8%.

Whose result confirmed an invasive ductal carcinoma with pathological staging II a.
