Breast cancer associated with mammary hamartoma.
Mammary hamartoma is an infrequent, nonmalignant lesion. Only 12 cases of carcinomas associated with a hamartoma have been previously documented in the literature. We describe a case of invasive ductal carcinoma arising in the mammary hamartoma during the follow-up period of a previously diagnosed hamartoma.
