  • Title: [Pathomorphology of gastric polyps].
    Author: Aruin LI.
    Journal: Arkh Patol; 1981; 43(3):52-60. PubMed ID: 7236033.
    Abstract:
    A total of 131 gastric polyps removed by endoscopic polypectomy in 108 patients were examined. According to Elster's classification, foveolar hyperplasia was diagnosed in 21 cases, foveolar hyperplasia with transition into hyperplasiogenic polyp in 3 cases, hyperplasiogenic polyp in 59 cases, hyperplasiogenic polyp with transition into adenomatous polyp in 4 cases, highly differentiated adenoma in 5 cases, adenomatous polyp in 5 cases, and other processes in 34 cases. Hyperplasiogenic polyps are characterized by the presence of chronic erosions (78.3%) and cysts (70%). In the process of reparative regeneration of erosions the emergence of cysts could be followed. The appearance of erosions was preceeded by dystrophic changes of the epithelium during which RNA accumulated in the adjacent epitheliocytes. This may be regarded as the state of "readiness" for reparation even before the defect of the mucous membrane develops.
