Gastric Adenocarcinoma of Fundic Gland Type.

A 61-year-old woman presented with a 2-week history of abdominal distension. She had no documented medical history. Abdominal examination was unremarkable. Upper gastrointestinal endoscopy showed a reddish erosive lesion of 15 × 12 mm on the greater curvature of the upper gastric body (Fig. 1A), which was well-defined by magnifying endoscopy with narrow-band imaging model (Fig. 1B, C). Biopsy was subsequently taken. Well differentiated columnar cells with moderate nuclear atypia were confirmed by microscopic examination.
