Two Cases of Neuroendocrine Carcinomas of the Stomach: Large Cell Carcinoma and Small Cell Carcinoma / 대한소화기내시경학회지

ABSTRACT

Neuroendocrine carcinoma of the stomach is an uncommon cancer with a high grade malignant behavior and a poor prognosis. The classification of gastric neuroendocrine carcinomas and its biologic characteristics remain controversial. It can be subdivided into the large cell and small cell variants based on its morphological characteristics. The low incidence of this tumor has contributed to the limited knowledge regarding its treatment and prognosis. We report here on two cases of primary neuroendocrine carcinomas of stomach, large cell and small cell carcinomas, respectively, along with a review of the literature.
