A 43-year-old woman presented with abdominal pain, nausea, and vomiting. She underwent computed tomography of the abdomen and pelvis that showed a gastric subepithelial mass. Esophagogastroduodenoscopy (EGD) revealed a smooth subepithelial mass in the fundus of the stomach, 5 cm distal to the gastroesophageal junction [Figure 1]. EUS demonstrated a homogeneous, hypoechoic 14 mm × 9.7 mm lesion, originating in the gastric submucosa [Figure 2]. The pancreas had an unremarkable endosonographic appearance. EUS-FNA was performed with a 22-gauge needle. While endosonographic appearance and location were most suspicious for gastrointestinal stromal tumors (GISTs), cytology was surprisingly consistent with an ectopic pancreas (EP).
