Abstract
Paraovarian cysts develop near the ovaries and fallopian tubes in the pelvic region. We describe our experience with a case of endometrioid carcinoma arising from a paraovarian cyst to help others better understand its presentation and management. The patient was a 49-year-old woman (gravida 4, para 3) who presented with complaints of right hypochondrium pain. She underwent laparotomy based on a preoperative diagnosis of malignant ovarian tumor. As the intraoperative pathological diagnosis of the tumor was a borderline malignant tumor, a total abdominal hysterectomy, bilateral salpingo-oophorectomy was performed. Histologic findings were endometrioid carcinoma arising from the paraovarian cyst. After discussion with the patient and her family, we decided to forego adjuvant therapy and lymph node dissection and to continue with outpatient clinical follow-up only.
