摘要

我們報告一例胃內翻型增生性息肉合併出血性胃潰瘍。這種胃息肉的組織型態極爲罕見，主要以黏膜層上皮翻轉內生至黏膜下層爲特徵。大多數胃內翻型增生性息肉的病人無臨床症狀。這位68歲有心肌梗塞病史的男性病患臨床表現爲吐鮮血及解黑便。上消化道鏡檢發現胃的中體部有一個黏膜下層腫塊及胃潰瘍。外科以局部胃切除取出腫塊，大小爲28x26x8公釐。病理診斷證實爲內翻型增生性息肉。病人出院後在門診追蹤檢查6年均無併發症。本報告回溯文獻並探討病理發生機轉。

We report a case of gastric inverted hyperplastic polyp (IHP) combined with active bleeding ulcer. This is a rare histological type of gastric polyp and characterized by inversion growth of the mucosal epithelium into the submucosa. Most patients with gastric IHPs were asymptomatic. A 68-year-old man presented fresh bloody vomitus and tarry stool. Upper gastrointestinal endoscopy showed a submucosal tumor (SMT) with active ulcer in the middle body. Partial gastrectomy was performed to resect the tumor, measuring 28 mm x 26 mm x 18 mm. The pathological diagnosis was gastric IHP. The patient was discharged and subsequently followed-up for 6 years without complications. We discuss the pathogenesis of this polyp and review of the literature.
