[A case of a non-invasive carcinoma of the breast with unusual clinicopathological appearance].

A rare case of a non-invasive carcinoma of the breast is reported. A 39-year-old woman was admitted to our hospital complaining of large breast lump (11.5 X 8.0 cm) and an abnormal nipple discharge. Mammography revealed widely dispersed microcalcifications and an echographic diagnosis indicated a fibrocystic disease. A cytologic examination of the nipple discharge showed malignant cells with a CEA level that was very high. The patient was treated with a standard radical mastectomy. Specimen mammography showed microcalcification in almost all sections. The histological examination, using serial sections, was seen to be consistent with a non-invasive ductal carcinoma. No lymph node or remote distant metastasis was found.
