Abstract

This article reviews the cause and clinical and pathologic features of gastrointestinal carcinoid tumors and small cell carcinomas. Their pathogenesis and molecular features are reviewed. Tumor arrays within a given site, as in the stomach, are compared with one another to highlight their histologic features and differing biologies. General treatment guidelines are also provided.
