NCI: A well differentiated neuroendocrine neoplasm that arises from the ovary. Histologically, it is classified as insular, trabecular, mucinous, or stromal carcinoid. Clinical manifestations of carcinoid syndrome occur in approximately thirty percent of patients with insular carcinoid tumor. Carcinoid syndrome is rare in other types of primary ovarian carcinoid tumor. With the exception of mucinous carcinoid tumor, the prognosis is favorable. Primary ovarian mucinous carcinoid tumor has a more aggressive clinical course and it can metastasize to other anatomic sites.
