case_images: Gastroscopy revealed a 12mm polypodial lesion with pseudopedicled morphology at the gastric level, presenting ulceration of its surface with endoscopic stigmata of recent bleeding ( Figure 1 ).
case_images: Polypoid formation that presents on the ulcerated surface, in which a tumor can be seen in the lamina propria made up of glands of different sizes, some dilated, which are covered by cells that have large clear cytoplasms and slightly irregular nuclei with small nucleoli eosinophils. They are separated by an edematous stroma.

case_images: In the histological analysis of the gastric polyp, a polypoid formation with an ulcerated surface is described, in which a tumor consisting of cells of different sizes, some dilated, covered by cells with large clear cytoplasms and slightly irregular nuclei, is observed in the lamina propria ( Figure 2 ).
case_images: Immunohistochemical staining with CD10 and Keratin CAM5.2 which are positive. The immunohistochemical profile is compatible with clear cell renal carcinoma metastases.
