Correlations between echo heterogeneity patterns with pathology in gastric gastrointestinal stromal tumors. Case 1 A: Endoscopy revealed a gastric body subepithelial lesion (SEL). B: MEUS identified a hypoechoic lesion with hyperechogenic spots from muscularis propria. C1-2: Histopathology confirmed intralesional calcification (C1 for HE staining x100, see blue box; C2 for HE staining x400). Case 2D: Endoscopy revealed a gastric fundus SEL. E: MEUS identified a hypoechoic lesion with marginal halo and cystic changes from muscularis propria. F1-2: Histopathology showed a pseudo-capsule of reactive fibrous tissue (F1 for HE staining x100, see orange box and white line; F2 for HE staining x400). G1-2: Lamellar fibrous tissue was observed (G1 for HE staining x100, see in green box; G2 for HE staining x400)
