Lobular carcinoma in a mammary hamartoma.
Mammary hamartomas are uncommon breast lesions, sometimes presenting as mammographic abnormalities which require pathological clarification. Previous cases have all been benign. A unique case of mammary hamartoma containing atypical lobular hyperplasia (ALH), lobular carcinoma in situ (LCIS), and foci of microinvasive lobular carcinoma is presented. The need for adequately sampling macroscopica...
متن کاملMicroinvasive lobular carcinoma associated with intraductal spread arising in a mammary hamartoma.
A 53 year old woman presented with a lump in the inner lower quadrant of the left breast. Histological examination of the breast tumour confirmed that the lesion was a mammary hamartoma.

Hamartomas may be associated with other benign lesions of the breast, and in very rare cases can coincidental malignancies occur. Herein, we describe a unique case of mammary hamartoma that has developed in ...
