Neuroendocrine tumor of the breast.
Mammary carcinoid is an uncommon neoplasm. It accounts for approximately 5 per cent of all breast carcinomas. It is well-known that neuroendocrine elements can be demonstrated in ductal and lobular carcinoma. However, it is still controversial whether mammary carcinoid tumors should be considered a distinct clinical entity or be treated as a variant of conventional breast carcinoma. Differentiating these lesions from benign lesions such as epithelial hyperplasia and papillomas can be challenging at times. We present a case of neuroendocrine tumor of the breast.
