The major invasive tumor types of carcinoma breast include infiltrating ductal, invasive lobular, ductal/lobular, mucinous (colloid), tubular, medullary and papillary carcinomas. Of these, infiltrating ductal carcinoma (IDC) is, by far, the most common subtype accounting for 70–80% of all invasive lesions. Combination of more than one pathological form is a very rare phenomenon. Here, we present such mixed mucinous and infiltrating ductal type in a male breast carcinoma.
