Is there a role for hormonal therapy in neuroendocrine carcinoma of the breast? A Paradigmatic case report.

However, because neuroendocrinemarkers are not routinely used on breast tumors with solid,alveolar, and nested patterns of growth, its real incidence isdifficult to assess and probably underestimated. NEBCs may begrouped into 3 subtypes: small-cell, large-cell, and carcinoid-likecarcinomas. Overall, the estrogen and progesterone receptorswere reported to be expressed in about 90% and 83% of NEBCs,respectively.
