Laparoscopic treatment of a complex adnexal mass of the retroperitoneal space: A case report

Complex adnexal cystic masses in women of reproductive age should be carefully evaluated before the final diagnosis is set. Adnexal cystic masses are not necessary malignant. On the contrary, they usually refer to a benign and not cancerous pathology. A certain benign pathology behind adnexal masses is endometriosis. Endometriosis occurs in 10-15% of women of reproductive age and presents great diversity both in the way it manifests and in its location. We report a case of a multiparous woman of reproductive age that was referred to our clinic due to abdominal and back pain. The imaging examinations revealed a cystic mass of the left parametrium that was laparoscopically removed. The histopathology set the diagnosis of endometrioma. The aim of our work is to highlight the endometrioma of the retroperitoneal space as part of the differential diagnosis of the cystic masses of the parametrium.
