“…The histogenesis of extraovarian SCST has been a topic of discussion in the literature, and it is speculated that extraovarian SCST originates from postsurgical implants, postinflammatory implants, an accessory ovary, a supernumerary ovary, or ovary autoamputation. 11,34-36 An accessory ovary is excess ovarian tissue that is situated near the normally placed ovary. A supernumerary ovary is ovarian tissue that separates from the normally placed ovary.…”

Extraovarian sex cord-stromal tumor is an exceedingly uncommon entity that may cause a diagnostic dilemma clinically. We report a case of extraovarian fibroma with minor sex cord elements arising in the left broad ligament. The patient was a 66-year-old woman presenting with an intra-abdominal solid mass near the left ovary on magnetic resonance imaging. The tumor was located in the left broad ligament in contact with the left ovary and fallopian tube based on laparotomy findings. Histological examination revealed that the tumor was a fibroma that contained cell nests with aggregates resembling the Call-Exner bodies of granulosa cell tumors and irregularly shaped cell nests composed of undifferentiated sex cord-type cells. Cellular atypia or mitotic figures were not identified in any of the components. It was speculated that the possible site of origin of this tumor might be a supernumerary ovary in the broad ligament that was thought to be derived from embryonic remnants.

“…The presence of an abnormally located ovary is known to be associated with other congenital malformations, mainly pelvic and renal, in up to 36% of cases. 1 Different types of tumors have been reported in ectopic ovarian tissue such as cystadenomas, 4 benign teratomas, 5,6 Brenner's tumors, 7 and fibromas with Meig's syndrome. 8 There have also been cases reported in which an ovary with a benign teratoma had auto-amputated and transplanted in an indirect inguinal hernia 6 and in the recto-uterine cul-de-sac, rectosigmoid colon mucosa 9 secondary to torsion.…”

Background: The presence of an ''ectopic ovary'' is rare, and the diagnosis can be difficult to establish preoperatively. Histologic confirmation is usually necessary. There has not been any case reported so far of a true ectopic ovarian leiomyoma as a cause of chronic pelvic pain. Such a case is reported in this article. Case: A 32-year-old woman presented with an incidental finding of a solid pelvic mass that had been diagnosed with a ultrasound (US) scan during a miscarriage that she had. During follow-up, she reported having symptoms of pelvic pain and deep dyspareunia. A repeat US scan showed no change in the mass that appeared to be arising from, or abutting, the posterior wall of her uterus, suggestive of a fibroid growth. Standard serum tumor markers were all normal. Magnetic resonance imaging (MRI) initially showed on only a hemorrhagic ovarian cyst. However, an initial diagnostic laparoscopy revealed a normal left ovary with a hemorrhagic cyst and a normal right ovary. However, there was also a separate solid, fibroidlike mass in her recto-uterine pouch of Douglas. Because her symptoms were persistent, a second laparoscopy was performed 10 months later, and the fibroid mass was resected. Surprisingly, the histology showed features of an ovarian leiomyoma that was considered to be ectopic in origin, as it was separate from both ovaries and was not attached to any of the adnexal structures or uterus. Results: The patient had an uneventful recovery and was completely symptomfree on follow-up. Conclusions: To the current authors' knowledge, this is the first case of a true ectopic ovarian leiomyoma reported. Successful management was achieved with minimally invasive surgery.
