Primary umbilical endometriosis: case report and literature review of an unusual cause of catamenial umbilical pain

[摘要] Endometriosis is defined by the presence of functional ectopic endometrial tissue outside the uterine cavity, excluding the myometrium . It is a benign tumor that can infiltrate and cling to other organs, mimicking a malignant tumor. Umbilical endometriosis is a rare type of endometriosis that can occur naturally or as a result of a surgical operation. We report the case of a patient who experienced catamenial umbilical discomfort and whose radiological examination revealed endometriotic involvement.
