Abstract

This report documents the diagnostic histopathological features of heterogeneous breast carcinoma following sepsis and disruption of the lactiferous ducts in a lactating woman and discusses the pathogenesis. Sections from the nipple revealed disrupted collecting lactiferous ducts presenting with intraduct precarcinoma and carcinoma of the epidermoid type, and attached reparative sprouts lined by lactiferous cells. Breast lobules showed generalised benign adenotic change with various foci of carcinoma microscopically identifiable as intraduct primitive lactiferal ectodermal carcinoma, lactating carcinoma, primitive neuroendocrine carcinoma and myoepithelioid granulomatous carcinoma. The findings led to the conclusion that the lactiferous ducts are susceptible to sepsis and disruption, which may predispose a patient to breast carcinoma. The pattern of carcinoma suggested that lactiferous epithelial cells behaved colonially, with different metaplastic changes, precarcinoma and carcinoma.
