Bilateral Neuroendocrine Carcinoma of Breast: A Case Report.

Primary neuroendocrine carcinomas of the breast are rare of all breast carcinomas. They may be welldifferentiated, poorly differentiated, or invasive breast cancers with neuroendocrine differentiation. They are staged and treated similarly to conventional breast cancer. Herein, we report a case of invasive ductal carcinoma with neuroendocrine differentiation of the breast in a 73 years female with a history of breast lump initially in the lower inner quadrant of left breast and a month later, similar lump at the same site in right breast. Patient underwent Modified Radical Mastectomy bilaterally followed by adjuvant chemotherapy based on Carboplatin and Etoposide regimen.
