A Case of Primary Small Cell Neuroendocrine Carcinoma in the Stomach

Abstract

Primary small cell neuroendocrine carcinoma in stomach is known to be very rare and only the twelve cases have been reported in the English literature. This tumor appears to be analogous to small cell carcinoma and carcinoid tumors of the lung, and is characterized by a very aggressive clinical course. Recently, we have experienced a 68-year-old man with primary small cell neuroendocrine carcinoma in the stomach, which had liver metastasis and peritoneal seeding. A positive Grimelius stain was present and immunohistochemical studies revealed positivity for neuron-specific enolase in the tumor. For its rarity, we report this case with review of literatures.
