Chiara Riviello, Mauro Cozzolino and Dora Pavone

Ovarian endometriomas are a common presentation of endometriosis. Surgery is considered the first therapeutic approach of endometriomas larger than 5 cm. We present a case of a right ovarian endometrioma with a size of 9 cm, which did not undergo to ovarian surgery due to anesthetic contraindication that was reduced after a prolonged treatment with dienogest 2 mg per day. We take note that in this case dienogest 2 mg per day used for over 22 months has reduced ovarian cyst since avoiding surgery.
