Secretory Carcinoma of the Breast: A Rare Entity With Favorable Prognosis.

Secretory breast carcinoma (SBC) is an extremely rare entity of breast cancer, which can affect all age groups. The diagnosis is based on the characteristic microscopic appearance, and despite the triple negativity or low hormone receptor positivity, SBC is generally characterized by a favorable prognosis. Due to the rarity of the disease, no clear consensus on optimal treatment is available. Nevertheless, conservative surgery or mastectomy is the main therapeutic option. The efficacy of chemotherapy, radiotherapy, and hormone therapy in this pathology has not been rigorously explored. We report the case of a 65-year-old woman with SBC treated with surgery and adjuvant radiotherapy, with a review of the literature.
