Primary breast carcinoma with neuroendocrine features is an extremely rare and underrecognized subtype of the breast carcinoma. And up to present, its biologic behavior, the most effective treatment, and prognosis are not well recognized. To diagnose this rare entity, special tumor stains of neuroendocrine markers are required, which are not routinely used. The imaging features of primary breast carcinoma with neuroendocrine features (BCNF) have not been accurately described due to the extreme rarity of this tumor type. We report the imaging features in a case of BCNF, with imaging findings different from the typical imaging findings of invasive breast carcinoma.
