Gastric Endocrine Cell Carcinoma Coexistent with Adenocarcinoma
Figure 1
Upper gastrointestinal series revealed a 5 cm ulcerative lesion with irregular margins and elevated distinct borders from the angle to the pyloric ring (a). Gastroendoscopy revealed a Borrmann type 2 tumor, extending from the angle to the antrum of the lesser curvature (b). The tumor comprised two different parts: ulcers with severe invasiveness and smooth protrusion from the endocrine cells and well-differentiated adenocarcinoma cells, as revealed by specimens biopsied under gastroendoscopy.
