Fibrosis as a key link in the morphogenesis of extragenital endometriosis

Abstract

The clinical of extragenital endometriosis is variable and depends on the localization, while the leading manifestation is a pronounced pain syndrome, which in some cases can simulate various surgical pathologies. Materials and methods: A morphological and IHC study was performed in 82 cases of extragenital endometriosis of various localization. Research results: An IHC study showed positive expression of -SMA in fibrosis foci around and between endometriosis foci. The expression area of TGF-1 was different for the cytogenic stroma and the perifocally located connective tissue. Conclusions: Fibrosis is an integral component of the morphogenesis of endometrioid heterotopias, while the degree of its severity depends on the duration of the existence of endometriosis foci. Severe pain syndrome is probably associated with deformation of organs and tissues, compression of nerve endings due to fibrosis processes.
