Abstract

Four unusual cases of primary mammary mucinous cystadenocarcinoma composed predominantly of tall columnar cells with abundant intracytoplasmic mucin are reported; they were multicystic and appeared virtually identical to mucinous cystadenocarcinomas of the ovary and pancreas. Three of the women were white and one was black, they ranged in age from 49 to 67 years (average 58), and they had tumors that ranged from 0.8 to 19 cm in diameter. Microscopically, the tumors were characterized by cystic spaces lined by predominantly bland-appearing columnar mucinous cells with stratification, tufting, and papillary formations. Varying degrees of cytologic atypia were focally evident, with gradual loss of the intracytoplasmic mucin and transformation to an eosinophilic squamoid cell population. Multifocal invasion generally emanated from these eosinophilic, squamoid areas in all cases. All four tumors displayed immunoreactivity for MIB-1 (Ki-67) in a relatively high percentage of cells and failed to show immunoreactivity for estrogen receptors and progesterone receptors. All four stained positively with cytokeratin 7 (CK7) but were negative with cytokeratin 20 (CK20). Mastectomy and axillary lymph node dissection were performed in three c...Continue Reading
