Case Report: Bilateral DCIS in a Male Patient

Male Breast Cancer (MBC) is a rare condition, only contributing to a very small number of total male malignancies. Due to the uncommon nature of Male Breast Cancer (MBC), diagnosis and treatment is often delayed, leading to a poorer prognosis than seen in female breast cancer counterparts. This is the case of a 52-year-old male with a family history of breast cancer that initially had presented with an episode of nipple discharge and a palpable breast mass. A rapid clinical evaluation was initiated and biopsy revealed Ductal Carcinoma In-situ (DCIS) in the left breast. Genetic testing was also performed, which resulted in a positive BRCA2 mutation diagnosis. Patient underwent a double mastectomy with sentinel lymph node biopsy. The postoperative pathology revealed that the patient had additional right-sided DCIS that had gone undiagnosed. It is intended for this report to demonstrate the importance of raising awareness of MBC both in the public and in health care providers. Additionally, it emphasizes the need for early diagnosis and rapid treatment of men with risk factors for MBC.
