A 57 year-old man with a 20-year history of a left breast mass presents to the ED with increased breast pain, skin changes, and discharge. He is diagnosed with invasive lobular carcinoma (ILC), which makes up 10-15% of all breast cancers, and 1% of male breast cancer diagnoses. ILC is defined by loss of the E-cadherin protein, encoded by the CDH1 gene. This case report details a rare case of invasive lobular breast cancer in a male patient with significant ILC disease burden.
