DCIS arising in mammary hamartoma

Mammary hamartoma is benign lesion and relatively rare. 17 cases of breast cancer associated with a hamartoma had been previously documented in the literature. We describe herein a case of noninvasive ductal carcinoma of the breast arising in hamartoma in a woman of 60’s. The discordance of images of the mass between mammogram and ultrasonogram can lead us to detect the carcinoma within the hamartoma in our case
