Primary neuroendocrine carcinoma of the breast (NECB) is one of the rarest subtypes of breast tumor, and for this reason, there are no data from prospective clinical trials on its optimal management. Its incidence is <0.1% of all breast cancers and <1% of all neuroendocrine tumors. The diagnosis of NECB requires the expression of neuroendocrine markers (chromogranin, synaptophysin, NSE) and the lack of simultaneous neuroendocrine carcinoma in extramammary sites. We present a case of a poorly differentiated neuroendocrine carcinoma (PD-NEC) metastasized in liver and lymph node after eight years. Mammography, ultrasound imaging, CT, and pathology findings are described.

A condition in which abnormal cells have not spread outside the duct, lobule, or nipple to other tissues of the breast. There are 3 types of breast carcinoma in situ: DUCTAL CARCINOMA IN SITU; LOBULAR CARCINOMA IN SITU; and PAGET DISEASE OF THE NIPPLE
Neoplasms, usually carcinoma, located within the center of an organ or within small lobes, and in the case of the breast, intraductally. The emphasis of the name is on the location of the neoplastic tissue rather than on its histological type. Most cancers of this type are located in the breast.
A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992)
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
