ABSTRACT

Fine needle aspiration cytology (FNAC) is an easy and rapid method in the differential diagnosis of breast masses. Papillary carcinoma, a rare malignant tumor of the breast, accounts for only 1-2% of the breast tumors. Benign and malignant papillary lesions of the breast can be difficult to distinguish in both cytological and histological preparations. Here we presented a case of suspicious lesion in FNAC, which was diagnosed as invasive papillary carcinoma in tissue.
