Submucosal lipoma of the upper gastrointestinal tract is a rare benign tumor. However, it may present as both a diagnostic problem and as a life threatening lesion due to exsanguinating hemorrhage. The authors report four patients with significant upper gastrointestinal bleeding due to ulcerating lipomas. In two patients the lesions were gastric and in two patients the lesions were duodenal in origin. In no instance could the diagnosis of lipoma be accurately established short of operative intervention because of unusual morphologic features. Surgical extirpation was necessary to stop the bleeding and establish the histologic diagnosis of the tumor.
上消化道黏膜下脂肪瘤是一种罕见的良性肿瘤。然而，它可能既带来诊断难题，又因出血性大出血而成为危及生命的病变。作者报告了4例因溃疡性脂肪瘤导致严重上消化道出血的患者。其中2例病变起源于胃，2例病变起源于十二指肠。由于形态特征异常，在手术干预之前，无一例能准确确诊为脂肪瘤。为了止血并确立肿瘤的组织学诊断，手术切除是必要的。
