BACKGROUND
Angiolipoma is a benign tumor and is generally found in subcutaneous tissues. Angiolipomas are rare in the gastrointestinal tract, including the stomach. Preoperative diagnosis of the tumor is difficult, although there are several radiological examinations such as computed tomography and endoscopic ultrasound.
CASE SUMMARY
We report a 24-year-old Chinese man with multiple gastric angiolipomas, with a positive stool occult blood examination. Endoscopic biopsy only showed nonspecific inflammation. Histological examination of the specimen by endoscopic snare resection showed that the tumor consisted of adipose tissues and blood vessels. We also performed a literature review. After the use of proton pump inhibitor, the fecal occult blood test was negative. Due to the difficulty of resecting multiple lesions in the stomach completely and the benign characteristics of angiolipoma, we chose to have regular upper gastrointestinal endoscopy evaluation of the lesion. No evidence of significant change in lesion size was detected after 3-years follow-up.
CONCLUSION
Gastric angiolipoma is rare, and benign neoplasm should be considered when lesions occur submucosally in the gastrointestinal tract.
背景
血管脂肪瘤是一种良性肿瘤，通常见于皮下组织。血管脂肪瘤在胃肠道（包括胃）中较为罕见。尽管有计算机断层扫描和内镜超声等多种影像学检查，但该肿瘤的术前诊断仍很困难。
病例摘要
我们报告一名24岁的中国男性，患有多发性胃血管脂肪瘤，粪便潜血检查呈阳性。内镜活检仅显示非特异性炎症。通过内镜圈套切除术对标本进行组织学检查显示，肿瘤由脂肪组织和血管组成。我们还进行了文献综述。使用质子泵抑制剂后，粪便潜血试验呈阴性。由于完全切除胃内多个病变存在困难且血管脂肪瘤具有良性特征，我们选择对病变进行定期的上消化道内镜评估。3年随访后未发现病变大小有明显变化的证据。
结论
胃血管脂肪瘤罕见，当胃肠道黏膜下出现病变时应考虑为良性肿瘤。
