Endometriosis is defined as ectopic presence of endometrial tissue outside of uterine cavity. Superficial peritoneal endometriosis is characterized by small superficial lesions modifying from white to dark brown shades. Dimension goes from few millimetres to 3 centimetres. We report a case of a 38 years old patient who has not had a signification in gynaecological pathology until five-six months before the gynecological check, when dysmenorrhea conditions associated at depth dyspareunia arose. Clinical and ultrasound investigations showed the presence of a pelvic cystic lesion, around 5 cm in diameter, diagnosed in the first instance as endometriotic cyst of the left ovary. The cystic lesion in the pelvis was confirmed by laparoscopic inspection. Really it was a large peritoneal implant (the left ovary was perfectly normal). The pathological report confirmed that a component of the lesion had nodules of florid endometriosis. It doesn’t exist ovarian cortex, but definitely a responsive mesothelium: the examined tissue has to be diagnosed with peritoneal endometriotic implant. Conclusions We refer to a case of peritoneal endometriotic implantation that has unusual dimensions (5 cm in diameter) late-onset in a woman who has experienced a specific symptomatology only in the last 6 months before the diagnosis
