Composite adenocarcinoma and carcinoid gastric tumor in chronic atrophic gastritis and pernicious anemia

Abstract

A 42-year-old Hispanic female was referred for investigation of unexplained weight loss. Initial upper endoscopy showed atrophic gastritis. Repeat endoscopy one year later revealed the presence of mixed composite tumor consisting of gastric adenocarcinoma and carcinoid tumors. Treatment was accomplished by surgical excision. Such cases are extremely rare and few such reports are available in the literature. We discuss the pathologies and means by which these tumors are classified and treated.

Keywords: Adenocarcinoma; Carcinoid; Collision tumor; Neuroendocrine; Stomach.
