Male breast cancer: Case report and review of literature

Abstract

Introduction: Male breast cancer (MBC) is an uncommon disease that makes up less than 1% of all breast cancer diagnoses worldwide. While breast carcinomas have some similarities in both sexes, there are significant differences. Case Report: We present a case of breast cancer in a 57-year-old man who had a left breast mass of 3.5 cm classified as breast imaging reporting and data system (BIRADS 4) by the American College of Radiology (ACR). The presence of invasive breast carcinoma of grade II Scarff–Bloom–Richardson (SBR) with a negative molecular phenotype B HER2 was confirmed by a tru-cut biopsy. The axillary cytopuncture did not show any abnormalities. The patient was later treated for a left mastectomy with homolateral axillary dissection. Conclusion: Male breast cancer represents a therapeutic dilemma. A multidisciplinary approach is mandatory.
