Lactating adenomas usually occur in patients who are young and are either pregnant or nursing.
The lesion is sharply delineated from the surrounding breast tissue. It has a lobulated arrangement
with fibrous bands separating the lobules. The ductal epithelial cells are distended with secretory
material within the cytoplasm which simply appears as intracytoplasmic vacuoles.
