P1648 Mixed adenoneuroendocrine carcinoma: a rare tumor of the gastrointestinal tract
Mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumor of the gastrointestinal tract. Classification requires at least a 30% component of both an adenocarcinoma and a neuroendocrine carcinoma. There are only nine reported cases in the cecum, which makes this case exceptionally rare.
