/Aims: The aims of this study are to clarify the morphology of fundic gland polyp (FGP) and to compare the features of FGP between familial adenomatous polyposis-associated group and sporadic development group. Methods: A total of 15 endo- scopic biopsy specimens of FGP from 13 patients were divided into three groups; Group A(3 cases; familial adenomatous polyposis family, multiple FGPs), Group B(3 cases; sporadic development, multiple FGPs) and Group C(7 cases; sporadic development, single FGP), and their endoseopic /microscopic features including mucin histochemistry and immunohistoc- hemistty(for PCNA) were compared. Results: FGPs were confined to the gastric body and fundus in all 3 groups, and measured 2-8 mm. Their numbers varied even in Group A and Group B, The difference was observed in their median age: 26 years in Group A and 55 years in Group B, respectively, but there were no differences in endoscopic, histologic, mucin histochemical and immunohistochemical(for PCNA) features. Micro-scopically, all FGPs were composed of fundic glands and scattered microcysts with a spectrum of disordered glandular architecture which ranged from convoluted gland to Y-shaped gland, to stellateshaped gland, and to irregular tortuous glancl with dilated lumen. Conclusions: We assume that diversity af morphologic features of FGP may develop from progression of hyperplastic/hamartomatous fundic glandular proliferation which may end up with microcyst formation as an evolutional change. Familial adenomatous polyosis-associated FGPs were not endoscopically and histologically distingishable from sporadic deveoped FGPs. (Korean J Gastrointest Endosc 17: 133-139, 1997)
