title: [Primary amyloidosis associated with early gastric carcinoma(IIb like IIa type) diagnosed by preoperative gastric biopsy--a case report].
abstract: A case of primary amyloidosis associated with intramucosal adenocarcinoma of the stomach, diagnosed by preoperative biopsy, is reported. A 77-year-old man was admitted to our hospital with complaints of vertigo and general fatigue. X-ray and endoscopic examination revealed a IIb-like IIa type protruded lesion on the cardia of the stomach. A biopsy specimen from the protruded lesion disclosed well differentiated tubular adenocarcinoma and amyloid deposition. Partial gastrectomy was performed on August, 18, 1981. Upon histological study, a diagnosis of primary amyloidosis associated with intramucosal well differentiated tubular adenocarcinoma was made. We suggest that the histogenesis of this gastric carcinoma was related to the gastric lesion due to primary amyloidosis. Careful review of the Japanese literature disclosed that ours is the first case report of primary amyloidosis associated with early gastric carcinoma diagnosed by pre-operative gastric biopsy.
