Esophagogastroduodenoscopy (EGD) was performed and it showed a large polypoid mass with superficial ulceration covered with whitish exudates in the anterior wall of the gastric antrum (Figure 1).
Post-contrast abdomen CT showed a submucosal lesion with diffuse fluid density in the anterior wall of the gastric antrum

Abdomen computed tomography (CT) showed an approximately 2 cm sized submucosal cystic lesion with diffuse fluid density in the gastric antrum without enhancement after contrast (Figure 2).
Endoscopic ultrasound showed a 2 cm sized isoechoic lesion at the third echo layer with echogenic portion on the luminal side of the lesion

Endoscopic ultrasound (EUS) showed an approximately 2 cm sized isoechoic lesion at the third echo layer with the echogenic portion at the luminal side of the lesion (Figure 3).
Photomicrography of resected specimen showed that the lesion had encapsulated adipose tissue at the submucosal layer and stromal fibrosis below superficial ulceration with detached normal mucosa (H + E, 15x)

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).
Microscopic finding showed blood vessels with thick walls among the mature adipose tissue. There were no visible fibrin thrombi within blood vessels (H + E, 100x)
