The average probability of malignant transformation in GHP is 0.6-22% in large series. The aim of the study was to present the coexistence of GHP with early gastric cancer (EGC), gastric adenoma (GA), neuroendocrine cell hyperplasia (NH) and well-differentiated neuroendocrine tumour (NET G1). Three cases were studied to reveal clinical data and morphological changes and to assess the relationship between GHP and accompanying gastric neoplastic lesions. %A Karpińska-Kaczmarczyk, Katarzyna %A Lewandowska, Magdalena %A Białek, Andrzej %A Ławniczak, Małgorzata %A Urasińska, Elżbieta %P 33-38 %9 journal article %R 10.5114/pjp.2016.59474 %U http://dx.doi.org/10.5114/pjp.2016.59474
