Carcinoid and other tumors metastatic to the breast

Abstract

Abstract Carcinoid tumor metastatic to the breast is extremely unusual; only six cases have been reported in the literature to date. Because of the rarity of these tumors primary or metastatic in the breast, and because tumors in general seldom metastasize to the breast, a review of primary carcinoid of the breast and tumors metastatic to the breast is included.
