Problem of endometriosis is one of the most actual in modern obstetrics and gynecology. This disease is called “a civilization disease”. Among endometriosis patients infertility is observed in 30% cases. Genital endometriosis is usually observed, but 6–8% of patients are suffering from extragenital form of endometriosis. In our clinic the exceptional case of the isolated form of extragenital endometriosis of the postoperative scar is registered. Detailed studying of this case with involvement of experts was carried out. Isolation of endometrioid defeat does not confirm any of classical theories of endometriosis development. However, the isolation of endometrioid lesions of genital endometriosis without source indicates a risk of development of this pathology in the group of patients with a burderned operating history. Immunohistochemical study of the isolated focus of endometriosis notes the high level of the expression of progesteron and moderate estrogen receptors, resulting in the need for hormone therapy in postoperative period. Prolonged therapy is provided by the change of aGnRH and oral progestogen drugs (dienogesta “Vizan”) and it ensures an adequate level of anti-relapse protection.
