[A Case of Laparoscopic Total Gastrectomy for Juvenile Polyposis of Stomach with Synchronous Multiple Intramucosal Carcinomas].

The patient was a 57-year-old woman. She was referred to our hospital because severe anemia. Upper gastrointestinal endoscopy revealed polyposis throughout the stomach and lobulated polyps in cardia, greater curve of middle body of the stomach, and angulus. Colonoscopy and small bowel endoscopy showed no obvious abnormal findings. Based on these findings, a laparoscopic total gastrectomy with D1 lymph node dissection was performed for suspected juvenile polyposis of stomach with severe anemia. The gross examination of the resection specimen revealed diffuse polyposis throughout the stomach, and histopathological examination revealed hyperplasia of the orbital epithelium throughout the stomach and lack of edema in lamina propria of mucous and eosinophil leukocytic infiltration, leading to the diagnosis of juvenile polyposis of stomach. Two well differentiated adenocarcinomas were found in 2 locations, which remained within the mucosa. We report a case of laparoscopic total gastrectomy for juvenile polyposis of the stomach with gastric cancer, with some discussion of the literature.
