Fragments of polypoid gastric mucosa characterized by marked foveolar hyperplasia. The surface and crypt epithelium show elongated, irregularly branched, and tortuous foveola, many of which exhibit prominent cystic dilation. The lining consists of a single layer of well-differentiated, benign-appearing, mucin-rich columnar cells with basally oriented nuclei. There is no evidence of nuclear stratification, significant pleomorphism, or atypical mitotic figures to suggest dysplasia or malignancy. The intervening lamina propria is expanded by edema, proliferating small blood vessels (congestion/focal hemorrhage), and a moderate to dense patchy chronic inflammatory infiltrate composed predominantly of lymphocytes and plasma cells. No evidence of H. pylori characteristic forms.
Known case of epilepsy presented with epigastric pain and vomiting. Endoscopy revealed antral sessile polyp.
Soft tissue fragments collectively measured 0.4 cm, totally embedded.
