Abstract
Histological, histochemical and immunohistochemical studies of 50 solitary juvenile polyps (JP) and 50 JP from children with juvenile polyposis syndrome (JPS) were performed. Observations of the focal complex glandular structures with high mitotic rate were more frequent in JP from patients with JPS (n = 29, 58%) than in solitary JP (n = 17, 34%) (p < 0.03). The immunohistochemical study demonstrated p53 overexpression in individual cells and more than 50% of Ki-67-positive cells in 5 (10%) solitary JP and in 17(34%) JP from patients with JPS (p < 0.007). The finding of microglandular pattern is more typical for JP from patients with JPS. Pathological data, expression of p53 and Ki-67 by immunohistochemistry could help to pick out the group of JP with dysplastic changes.
期刊介绍：
The journal deals with original investigations on pressing problems of general pathology and pathologic anatomy, newest research methods, major issues of the theory and practice as well as problems of experimental, comparative and geographic pathology. To inform readers latest achievements of Russian and foreign medicine the journal regularly publishes editorial and survey articles, reviews of the most interesting Russian and foreign books on pathologic anatomy, new data on modern methods of investigation (histochemistry, electron microscopy, autoradiography, etc.), about problems of teaching, articles on the history of pathological anatomy development both in Russia and abroad.
