Primary papillary serous carcinoma presenting as acute ovarian torsion in postmenopausal woman: a case report

A 51-year-old postmenopausal woman, with an uneventful past gynecologic history, was admitted to the present hospital with a diagnosis of severe pelvic pain due to a suspected ovarian torsion treated with different drugs intravenously without any improvement of symptoms. As a consequence of the increasing pelvic pain, a laparoscopic surgical treatment was decided: a left necrotic ovarian mass and pelvic peritoneal carcinomatosis were visualized and the procedure was converted from laparoscopy to laparotomy that confirmed a diagnosis of primary ovarian papillary serous carcinoma and permitted an adequate treatment. This is a rare case in literature of severe pelvic pain due to an acute ovarian torsion that permitted a prompt diagnosis and treatment of malignancy.
