Abstract
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.

Core tip: Angiolipoma in the gastrointestinal system is a rare entity, and angiolipoma in the stomach is extremely rare, with difficult preoperative diagnosis. We report a patient with multiple gastric angiolipomas with weakly positive stool occult blood examination. Endoscopic and radiological examinations, such as computed tomography, were used. The specimen was obtained by endoscopic snare resection for histopathological evaluation. Multiple angiolipomas in the gastrointestinal system are extremely rare in the recent literature. We also performed a brief review to investigate the clinical characteristics, diagnosis, and management of gastric angiolipoma.
