Invasive Breast Carcinoma: Rare Clinical Presentation in a Male Patient

Abstract

A 74-year-old male presented for evaluation of a right breast mass that the patient had self-detected a few weeks prior. This gentleman had an extensive family history of cancer, with a father (70 years old) and daughter (31 years old) with breast cancer, a sister with rectal cancer (70 years old), and a son and daughter with a pathogenic variant of the breast cancer (BRCA) gene. As with women, the frequency of malignancy increases with age. Many similar risk factors are noted to overlap between male and female presentations. Men tend to have similar profiles and presentations as postmenopausal women. The vast majority are diagnosed early, and less than 5% present with metastatic disease. This case report highlights the imaging presentation of this rare diagnosis and reviews its etiology and pathophysiology.
