To the hospital, a 27-year-old woman presented with a 3-week H/o burning epigastric pain, nausea, early satiety, and constipation. 

Despite the immense size of the mass, the lack of lymphadenopathy, no family history of cancer, and no known genetic predispositions made it less likely to be an epithelial malignancy (gastric or pancreatic carcinoma).

Physical examination revealed epigastric and right upper quadrant tenderness with routine laboratory workup. Still, imaging revealed a 5-cm, partly cystic mass arising from the gastric antrum with resulting pyloric stenosis and partial gastric outlet obstruction, as shown in the figure. In addition, endoscopic ultrasound-guided fine-needle aspiration revealed – an abnormal pancreatic tissue lying in a non-physiological site. The patient underwent resection and recovered with a complete pathologic examination showing normal exocrine pancreatic tissue (PH type 2) without malignant transformation.
