Concurrent Lactating Adenoma and Infiltrating Ductal Carcinoma: A Case Report

Abstract

A lactating adenoma is a benign tumour which usually occurs in younger women who are either pregnant or breast feeding. In some instances these lactating adenomas can occur simultaneously with breast carcinoma, so they have to be carefully evaluated. We report an unusual case of simultaneous occurrence of a lactating adenoma and infiltrating ductal carcinoma occurring in a 25-year-old lactating mother.
