A 35-year-old woman underwent esophagogastroduodenoscopy for progressive epigastralgia. A 10mm subepithelial antral lesion contained plasmocytoma tissue. Diagnostic work up was negative apart from a gastric focus on PET.

Endoscopic evaluation after radiotherapy, suggested a non-responding lesion. Endosonography observed a homogenous, hypoechoic, submucosal mass.

Conventional ESD was performed, taking 1cm lateral margins, dissecting alongside the muscular layer. En bloc resection (60x40mm) was obtained. Pathology confirmed a submucosal plasmocytoma. Margins were free. Evaluation at six months showed ESD scarring in an asymptomatic patient, follow up was proposed.

ESD can serve as treatment for digestive plasmocytoma, beyond the scope of its established indications.
