Synchronous endometrioid carcinoma of the ovary and endometrium associated with ovulation induction.
Over the last 2 decades great concern about the possible association between ovarian cancer and ovulation induction has been raised. Between the first reported case in 1982 and the end of year 2000, there have been 44 cases of ovarian carcinoma reported to occur in women previously treated with ovulation induction drugs. Most of these tumors were of the serous type with low malignant potential. In the present case, the patient had secondary anovulatory infertility and previous left cystoophorectomy for ovarian endometrioma. She was treated with human menopausal gonadotrophin alone or in combination with clomiphene citrate for 13 cycles prior to presentation. Screening ultrasound revealed multicystic right ovarian mass (15 x 9 x 6 cm). Hysterectomy and right salpingo-oophorectomy were carried out. Intraoperative and histological examinations showed stage 1A endometrioid ovarian cancer and well-differentiated endometrial adenoacanthoma with minimal myometrial invasion. A brief but critical review of published literature regarding the association of ovulation induction and increased risk of ovarian cancer is presented.
