Bottom Line: Endoscopic ultrasound showed an about 2 cm sized isoechoic lesion at the third echo layer, with the echogenic portion on the luminal side of the lesion.Laparoscopic wedge resection was performed and histological examination showed that the lesion had encapsulated adipose tissue at the submucosal layer and stromal fibrosis just below superficial ulceration.There were blood vessels with thick walls among the mature fat cells.

ABSTRACT
Angiolipoma is a morphological variation of the lipoma and is a benign tumour that consists of mature adipose tissue and proliferating blood vessels. It occurs very rarely in the digestive tract, especially the stomach. We report a gastric angiolipoma in a 58-year-old woman admitted for anaemia and melena. Endoscopy showed a large polypoid mass with superficial ulceration in the anterior wall of the gastric antrum. Endoscopic ultrasound showed an about 2 cm sized isoechoic lesion at the third echo layer, with the echogenic portion on the luminal side of the lesion. Laparoscopic wedge resection was performed and histological examination showed that the lesion had encapsulated adipose tissue at the submucosal layer and stromal fibrosis just below superficial ulceration. There were blood vessels with thick walls among the mature fat cells. Therefore, the lesion was diagnosed as an angiolipoma.

Mentions: It was a hard mass with ulcerated overlying mucosa that caused the bleeding. In addition, it did not show typical findings of a benign tumour, such as lipoma on EUS. Therefore, laparoscopic wedge resection was performed 11 days after initial admission. The specimen was a subepithelial tumour measuring 1.6 cm × 1.5 cm × 1.4 cm. The cut surface of the mass was yellow and smooth. No necrosis was present. The overlying mucosa was ulcerated. Histological findings showed that the lesion had encapsulated adipose tissue at the submucosal layer and stromal fibrosis below superficial ulceration with detached normal mucosa (Figure 4). In microscopic findings, there were blood vessels with thick walls among the mature fat cells (Figure 5). There were no fibrin thrombi within the blood vessels. Therefore, the lesion was diagnosed as an angiolipoma. The patient had no specific complications of operation and was discharged 6 days after surgery.
