“…These findings suggest that the autoamputated tumor may have been implanted in the omentum and received a blood supply from omental capillary vessels. The omentum is one of the common sites of ectopic ovary and eight cases have been reported in the literature 3,5,6 …”

An ovary with a mature cystic teratoma which was autoamputated into the cul-de-sac and confirmed by laparoscopy is described. A 24-year-old woman with a history of chronic pelvic pain for 5 years presented with left abdominal pain. Magnetic resonance imaging revealed a left ovarian mass of 5 cm in diameter. The pain was relieved spontaneously after a few weeks. Laparoscopy was performed 5 months later. The mass was identified in the cul-de-sac partly enveloped in the omentum without any ligamentous or direct connection with the pelvic organs. There was no left ovary in its proper anatomical location. Histopathologic study revealed a mature cystic teratoma with viable ovarian tissue. These findings suggested autoamputation of the ovary either by inflammation or torsion, which is one of the mechanisms for the formation of an ectopic ovary.

“…5 Acquired conditions of ectopic ovarian tissue was reported due to inflammation and surgical operations, the ovarian tissue which had been detached from the ovary could be implanted anywhere in the pelvic cavity. 6 Supernumerary ovary was reported in the omentum, [7][8][9] in retroperitoneum, 10,11 and in the pouch of Douglas. 12,13 The literature reports various cases of tumors arising in ectopic ovaries, such as serous cystadenoma, dermoid cyst, Brenner tumor, sclerosing stromal tumor, steroid cell tumor, mucinous cystadenoma, teratoma and fibroma.…”

Ectopic ovarian tissue is a rare gynecologic condition. Accessory ovaries were defined as excess ovarian tissue adjacent and connected to a normal ovary, while supernumerary ovaries were described as those ovaries situated away from normal ones. The one presented here is a case of a 20 year-old unmarried woman operated for recurrent abdominal pain. During laparoscopy we found a mass 2×1.5 cm in size in the ileum, located 80 cm from the ileocecal valve: the lesion was resected and an ileoileal anastomosis was performed, the anatomopathological examination of the mass proved to be ovarian tissue. The history of previous pelvic surgery with adhesiolysis, and the unusual location of the ectopic ovary, support the theory of an ovarian implant in the intestine, but the true ectopic ovary hypothesis is still probable because of the location of the ectopic ovary inside the intestinal wall. In any case, the location of ectopic ovary discussed here is unusual and perhaps unpublished before.

“…Most supernumerary ovaries are incidental findings at autopsy, laparoscopy, or surgery. Rare cases of documented pathology in supernumerary ovaries have been reported [10, 11]. Other possibilities include derivation from Mullerian rests or from the mesothelium [12].…”

Background. Fibrothecomas are benign sex cord-stromal tumors which rarely originate outside of the ovary. To date, two such cases have been reported in the literature. We report the third case of an extraovarian fibrothecoma and the first presenting similarly to a metastatic epithelial ovarian cancer. Clinical History. We describe a 62-year-old woman with history, physical examination, and imaging suggestive of metastatic ovarian cancer. CA-125 was elevated at 1291 U/mL. Paracenteses were negative for malignant cells and core biopsy showed spindle cell proliferation. A primary debulking surgery for a presumed ovarian cancer was planned. Method and Results. At surgery, 6 liters of ascites were drained. The uterus, ovaries, peritoneum, and omentum were normal. An 18 × 11 × 7 cm retroperitoneal mass was found between the left ureter and the sigmoid mesocolon, wrapped with sigmoid colon. Fallopian tubes and ovaries were normal. The mass was resected en bloc with the sigmoid colon, uterus, ovaries, and omentum. Microscopically, there was spindle cell proliferation typical of fibrothecoma. No ovarian tissue was identified in association with the tumor. Conclusion. This third case of extraovarian fibrothecoma highlights the importance of obtaining histologic evidence of malignancy prior to initiating neoadjuvant chemotherapy for a presumed ovarian cancer.
