[A type IIa early carcinoma in multiple submucosal cysts of the stomach--a case report].
The case of a 60-year-old Japanese man with an early gastric carcinoma in submucosal multiple cysts is presented, and the morphology and histogenesis had complained of dysphagia, and an upper gastrointestinal barium study and endoscopy revealed an irregular-shaped, flat polypoid tumor in the antral mucosa. The resected stomach had a polypoid lesion, 11.0 x 12.0 cm, but no erosion or ulcer in the greater antral curvature was seen, and cut section showed many cysts containing mucus. A subsequent histological examination revealed a well differentiated adenocarcinoma of the mucosal layer. This early carcinoma was sited on and surrounded by multiple cystic lesions. These histological findings suggested that this carcinoma had developed from the mucosa that had an underlay of submucosal cysts.
