A mucus-secreting gastric submucosal tumor: Unique endoscopic finding of a rare case of plexiform fibromyxoma (with video)

A 43-year-old previously healthy female presented with a 3-day history of melena and mild anemia (hemoglobin 98 g/L). Esophagogastroduodenoscopy detected a 2.5-cm submucosal tumor-like (SMT-like) lesion with characteristic multiple dimples on the surface (Fig. 1A). Notably, close observation showed mucoid exudates covering these dimples, indicating an intralesional mucinous component (Fig. 1B). Endoscopic ultrasonography revealed a well-defined, hypoechoic submucosal lesion (Fig. 1C), whereas contrast-enhanced computed tomography demonstrated peripheral rim enhancement and central heterogeneity (Fig.
