“…These lesions are usually ulcers on the mucosal surface that are accompanied by active inflammation and reactive epithelial changes and exhibit fibrinopurulent exudates. 41 Preoperative colonoscopy biopsy is mostly confined to the mucosa, while angiolipoma of the GI tract is mainly located under the mucosa; thus, a biopsy may only show nonspecific features. Intraoperative frozen section evaluation may be a useful adjunct diagnostic method in the setting of local resection.…”

Objective Angiolipoma is a benign tumor that rarely occurs in the gastrointestinal (GI) tract. This case series was performed to increase clinicians’ understanding of the diagnosis and management of GI angiolipoma. Methods We evaluated the clinical presentations, diagnoses, and treatments of 3 patients with angiolipoma in the upper GI tract in our hospital and 27 cases reported in the literature. Results Among all 30 cases of GI angiolipoma, 2 originated in the esophagus, 4 in the stomach, 2 in the duodenum, 1 in the jejunum, 7 in the ileum, 1 in the cecum, 9 in the colon, 2 in the rectum, and 2 in both the duodenum and colon. Conclusion Angiolipoma of the GI tract may be more likely to occur in middle-aged and elderly men and be located in the ileum and colon. The clinical manifestations generally involve upper GI hemorrhage and lower GI pain and obstruction. Computed tomography and endoscopy may be effective diagnostic techniques, but postoperative histopathologic examination is still the gold standard. The management of angiolipoma in the GI tract depends on the size and type of lesion. Most cases in the present series were managed by complete surgical resection, after which no recurrence was found.

“…They are rarely seen in the gastrointestinal system[2]. Although endoscopic and radiological examinations can demonstrate the lesion in the gastrointestinal tract, preoperative diagnosis of angiolipomas is still difficult and the final diagnosis is dependent on histopathological evaluation[3]. According to the current literature, only four cases of gastric angiolipoma, which all occurred as a solitary lesion, have been reported[4-7] (Table 1).…”

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.

“…Angiolipoma is a rare and benign variant of lipoma that usually occurs as a subcutaneous tumor. It has a hypervascularity exceeding that of normal lipoma, especially if thrombosis is present within the blood vessels [2] , [3] . These tumors can occur as single or multiple tumors, and are usually located in trunk and upper extremities, and rarely in other areas such as hand, spinal region, breast, gastric, lungs, kidney [4] , [5] .…”
