Mixed Mucinous and Infiltrating Carcinoma Occurring in Male Breast-Study of Clinico-Pathological Features: A Rare Case Report

Abstract

Mucinous carcinoma is a less common histologic variant of breast cancer. Cases of mucinous carcinomas in male breast are extremely rare. Here, we describe a case of mixed mucinous carcinoma i.e. mucinous carcinoma with infiltrating ductal carcinoma component and showing apocrine differentiation in a 73-year-old man. This uncommon tumour entity has dismal prognosis and treatment depends largely on the tumour type, size, lymph node involvement and hormonal status.
