title: Neuroendocrine carcinoma of the uterus.
abstract: Neuroendocrine carcinomas of the cervix and endometrium were reviewed. They have been variously designated as carcinoid, argyrophil cell carcinoma, apudoma, small cell carcinoma, oat cell carcinoma, endocrine carcinoma, and neuroendocrine carcinoma, the last-mentioned term being preferred in this chapter. Adenocarcinomas with neuroendocrine cells are occasionally encountered in the cervix and endometrium. It is generally questioned whether they should be included in the spectrum of neuroendocrine carcinomas, although differential diagnosis between some such tumors of the gastrointestinal tract and neuroendocrine carcinoma is reported to be difficult. Since the majority of neuroendocrine carcinomas of the cervix are highly aggressive, it is important to establish the neuroendocrine nature in the cervical carcinomas. In addition to the characteristic histologic features and argyrophil stainability, immunohistochemical demonstration of several neuroendocrine markers may be helpful in diagnosing neuroendocrine carcinoma of the cervix. Ultrastructural demonstration of neurosecretory granules is almost decisive in establishing the tumor's neuroendocrine nature, but it is not applicable in all cases. Neuroendocrine carcinomas of the cervix have been treated by surgery, radiation therapy, and chemotherapy, but optimal treatment methods have not yet been established because of the rarity of the tumor. Finally, we have described a typical neuroendocrine carcinoma of the cervix and reported some data regarding its experimental study.
