[Neuroendocrine carcinoma of the breast: about a case and review of the literature]. / Carcinome neuroendocrine du sein: à propos d'un cas et revue de la literature.

Primitive neuroendocrine carcinomas of the breast are rare tumors. They are now included in the latest WHO classification of tumors of the breast. We report the case of a 39-year old patient with tumor located in the breast. It was a locally advanced tumor that required mastectomy and ipsilateral axillary node dissection. Adjuvant chemotherapy was indicated. The evolution was marked by local progression. The patient died in a state of febrile pancytopenia after a one-year survival.
