A subepithelial lesion turns up in the second part of the duodenum and is referred for discussion. Reach for EUS? Resect it? Or can the diagnosis be made at the endoscope, in a couple of minutes, with the kit already in your hand? This short case works through the reasoning step by step — orientation against the major papilla, confirming the lesion is subepithelial rather than mucosal, testing mobility, the pillow sign, and the naked-fat sign that seals the diagnosis of lipoma.
