title: Papillary carcinoma of the breast. Fine needle aspiration cytology (FNAC) of two cases.
abstract: Cytologic findings of two cases of infiltrating papillary carcinoma of the breast are presented. Both cases showed highly cellular smears, prominent papillary configuration, and cohesive groups of polygonal cells with bland nuclei and scarce mitoses. Bipolar cells were not observed. A clean background with hemorrhage, lymphocytes and hemosiderin-laden macrophages was also found. Histologic sections confirmed the initial diagnosis and proved their infiltrating nature. Literature concerning its cytologic differential diagnosis is briefly reviewed and commented.
