Gastroscopic examination of this 32-year-old male patient showed a smooth protrusion at the greater curvature of the gastric body with a central depression,identified by subsequent biopsy as carcinoma. The patient had a normal serum gastrin level and was negative for anti-parietal cell antibody. Histological examination of the resected gastric tissues showed that the tumor was a carcinoid, 0.3 cm×0.3 cm in size with only one regional lymph node metastasis. We reviewed the pathogenesis,clinical presentation, diagnosis and treatment of gastric carcinoids and raise the possibility of being a lymph vesselrelated metastasis even for a minute carcinoid tumor.Sentinel lymph node biopsy is recommended for surgery of minute carcinoid tumors.展开更多
