Abstract
Endometriosis is a chronic hormone-dependent progressive disease characterized by the presence of ectopic endometrioid tissue. Most often, endometriosis affects the ovaries, fallopian tubes and the abdominal cavity, but endometrioid foci are also found in the intestines, heart, lungs, skin and other atypical localizations. This article presents a clinical case of retrocervical endometriosis diagnosed based on the results of pathological and histological examination. It is important to note the complexity of the differential diagnosis of this form of endometriosis due to secondary changes in the area of the colon and the absence of characteristic clinical manifestations.
