Rare coexistence of invasive papillary carcinoma with infiltrating ductal carcinoma in male breast: report of a case.

Invasive papillary breast carcinoma is a subtype of breast cancer that is more frequent in males. An intraductal carcinoma can coexist with it but association of an infiltrating carcinoma has not been described. This report presents a rare case of a 35-year-old man with dual malignancy in the same breast. The patient had two separate nodules, one with the morphology of invasive papillary carcinoma and the other having features of an infiltrating ductal carcinoma. To the best of our knowledge this is the first case report describing the coexistence of these two entities.
