From: SP70 is a potential biomarker to identify gastric fundic gland neoplasms
Histopathological features of fundic gland neoplasm. A Oxyntic gland adenoma (OGA) always consists of clustered and irregular fundic glands (HE, x100). B Chief cell–predominant OGAs with scattered parietal cells. Pigments could be observed in the dilated glands. C Complex glands with mild atypia neoplastic cells. D Gastric adenocarcinoma of fundic gland type (GA-FG) with submucosal invasion. E Muscular infiltration and vascular invasion (as indicated by the arrows) could be observed. F GA-FG (black arrow) with gastritis cystica profunda (white arrow)
