術前診断がsmで組織診断でもsmであった陥凹型早期胃癌の1例

Early Gastric Cancer with Submucosal Involvement Whose Preoperative Diagnosis of the Cancerous Depth Invasion Coincided with the Postoperative Findings, Report of a Case

　われわれは術前の深達度診断がsmで，組織診断でもsmであった陥凹型早期胃癌を経験し，その深達度診断について検討を加えたので報告する．

症状

　患　者：52歳，女．

　主　訴：左側腹部痛．

　現病歴：上記主訴が出現したため，1979年2月26日に胃集検を受け，胃角部後壁のひだ集中をチェックされ，当センターで精密検査を行った．

　The patient, 52-year-old woman with a lesion of Type Ⅱc+Ⅲ early gastric cancer measuring 43×16 mm and histologically confirmed as adenocarcinoma mucocellulare is reported. Its depth invasion reaches the submucosal layer.

　The reasons for the preoperative diagnosis of the patient as sm cancer are as follows:

　(1) The folds converge on the lesion all the way around it.

　(2) The ends of the folds adjacent to the lesion shows rod-like swelling.

　(3) The depression of the lesion is clearly defined.
