We report the case of a 62-year-old woman with no history of interest who presented with dyspepsia of 2 years’ standing. Gastroscopy revealed a subepithelial lesion at the greater antral curvature with irregular surface and preserved mucosal and vascular pattern, 15 mm in diameter. Because of clinical persistence a radial endoscopic ultrasonogram (EUS) was performed, which showed a well-delimited hypoechoic lesion with heterogeneous areas that was dependent on the muscularis mucosae layer. A biopsy was obtained using the “bite-on-bite” technique, which provided no pathological findings. With these findings an endoscopic submucosal dissection (ESD) procedure was performed with wide margins and no complications. Pathology found low-grade mesenchymal fusicellular proliferation dependent on the muscularis mucosae with immunohistochemistry positive for smooth-muscle vimentin and actin, consistent with plexiform fibromyxoma.
