Abstract
We report a rare case of glomus tumor of the stomach coexisting with gastric cancer. A 63-year-old man visited our hospital because of a sensation of abdominal fullness and was admitted with a diagnosis of pyloric stenosis for evaluation. Abdominal CT showed a mass at the pylorus which caused stenosis of the gastric lumen and induced gastric dilatation. There was a submucosal tumor observed at the oral side of the pylorus mass. The submucosal oval mass was strongly and heterogeneously enhanced. Cholelithiasis was diagnosed by abdominal sonograph. The pyloric tumor was diagnosed as gastric carcinoma by biopsy. The submucosal tumor without ulceration was also observed at the oral side of the cancer by endoscopy. Gastric cancer with pyloric stenosis, submucosal tumor and cholelithiasis were diagnosed preoperatively. Distal gastrectomy and cholecystectomy were performed. On the longitudinal cut surface of the type 3 tumor, the distal portion was white firm and the oral portion was brown soft. Pathologically the white portion was diagnosed as carcinoma and the brown one was glomus tumor.
