Secretory Carcinoma of the Breast.

Secretory carcinoma is a very rare subtype of breast carcinoma. These tumors are generally associated with a favorable prognosis, although having triple-negative phenotype (estrogen receptor (ER), progesterone receptor (PR) negative and c-erbB2 (HER2) negative). In this presentation, a rare secretory carcinoma of the breast in a woman aged 24 years is discussed and the literature is reviewed.
