Figure Lengend Snippet: The endoscopic presentation and pathological features of gastric LCH A : Endoscopic examination revealed a small polyp in the gastric body, measuring 0.5 cm in diameter. B : The tumor cells are located in the mucosal layer and show clear boundaries with the surrounding tissue (H&E, 200×). C : The tumor cells exhibit round or oval nuclei, with some cells showing nuclear grooves. Eosinophils are scattered in the background, and occasional mitotic figures are observed (H&E, 400×). D : Diffuse expression of Langerin (EnVision method, 400×). E : Diffuse expression of CD1a (EnVision method, 400×). F : Positive expression of Cyclin D1 (EnVision method, 400×). G : Positive expression of S-100 (EnVision method, 400×). H : Positive expression of Ki-67 (EnVision method, 200×).
