Invasive Ductal Carcinoma Arising within a Mammary Hamartoma: Case Report

ABSTRACT

Breast hamartomas are typically a benign condition and rarely develop into malignant lesions. The coexistence of carcinoma and a breast hamartoma is rare; only 15 cases have been reported in the literature. Here, we report a case of invasive ductal carcinoma associated with hamartoma in a 60-year-old woman. Mammography, ultrasonography and magnetic resonance imaging showed typical features of a breast hamartoma and a suspicious mass with microcalcifications arising within the hamartoma.
