Primary sebaceous carcinoma of the breast is an exceedingly uncommon neoplasm that is defined as primary invasive carcinoma of the breast with sebaceous differentiation in more than 50% of cells. All confirmed cases have been reported in women. Herein, we report the case of a 70-year-old man with a primary sebaceous breast carcinoma, the first unequivocal case to be reported thus far in a man.
