Supernumerary ovary associated with Wilms' tumor

A Rare Ectopic Ovary Mimicking Colon Sigmoideum Mesenchymoma Presenting as an Intestinal Mesenchymoma

Ectopic ovaries are a rare occurrence. A 33-year-old woman presented to our unit for evaluation of a 2-year history of sporadic abdominal pain that was becoming sharp and frequent. Computed tomography (CT) suggested a gastrointestinal tract mesenchymoma. An abdominal laparotomy was performed and the tumor was excised for pathologic evaluation. A rapid frozen section pathologic examination showed a solitary fibrous tumor (SFT). The final pathology report was an ectopic ovary with corpora lutea bleeding. Ectopic ovaries are benign and the present case is the first report involving an ectopic ovary mimicking a gastrointestinal stromal tumor (GIST). The patient recovered well after surgery. Maldevelopment of the genital tract can lead to ectopic ovaries and surgery is a good management choice. The present case provides a possible differential diagnosis for GISTs.

Dysgerminoma developing from an ectopic ovary in a patient with WAGR syndrome: A case report

WAGR syndrome is caused by an 11p13 deletion and includes Wilms' tumor, aniridia, genitourinary anomalies and mental retardation. We encountered a case of a dysgerminoma originating in an ectopic ovary in a woman with WAGR syndrome. Our patient was a 24-year-old nulliparous woman who was diagnosed with WAGR syndrome. The patient had undergone left nephrectomy for a Wilms' tumor and postoperative chemotherapy at the age of 7 months. She also had a history of glaucoma surgery in both eyes, and was followed up at the Department of Pediatrics for diabetes mellitus, hypertension, liver dysfunction and hyperuricemia. The patient was investigated for oliguria and had elevated levels of blood urea nitrogen (45 mg/dl) and creatinine (5.4 mg/dl); she was admitted to the hospital with acute renal failure and a computed tomography scan revealed a pelvic tumor with a long axis of 10 cm that was obstructing the right ureter. Following insertion of a ureteral stent, the tumor was removed. The tumor had developed in the retroperitoneal space independent of the ovaries. The right adnexa were normal. The tumor was histopathologically diagnosed as dysgerminoma. Follicles were found in part of the tumor; it was thus hypothesized that the tumor developed from an ectopic ovary. The patient was administered etoposide after surgery, and has been recurrence-free for 4 years since treatment.

Mature Teratoma in a Supernumerary Ovary in a Child: Report of the First Case

BACKGROUND

Supernumerary ovary (ie, ovarian ectopia having no anatomic connection with the normally placed ovaries) is a rare gynecologic condition. To the best of our knowledge, only 1 pediatric case of supernumerary ovary has been reported to date in the English literature.

CASE

A 4-year-old girl was assessed for foul-smelling vestibular discharge and was found to have a fistulous tract with opening near the vaginal orifice. Fistuloscopy revealed hair in the lumen of the tract. Computed tomography scan showed a retroperitoneal mass in continuation of the tract. Excision of the mass revealed a mature teratoma in a retroperitoneal supernumerary ovary.

SUMMARY AND CONCLUSION

Supernumerary ovary, a gynecologic rarity, is even more uncommon in children. Hence, a thorough clinical-radiological-pathological correlation is mandatory to diagnose extragonadal ovarian tumors arising in supernumerary ovaries.

Lymphangioma of the ovary after radiation due to Wilms' tumor in the childhood

OBJECTIVE

To report a case of lymphangioma of the ovary after radiation due to Wilms' tumor in the childhood.

PATIENT

A 19-year-old nulliparous female.

INTERVENTIONS

The vaginal ultrasound showed the left ovary enlarged to 4.4 cm x 2.9 cm x 4.5 cm in size including a 3.5 cm x 2.6 cm x 3.2 cm measuring cystic solid tumor without hypervascularity. For exclusion of a malignant tumor, a laparoscopy for excision of the tumor and deep incision of the left ovary with a bipolar needle was performed to exclude deeper tumor of stromal origin. The histological examination of the tissue showed a lymphangioma beside normal ovarian tissue.

CONCLUSION

To our knowledge, this is the first report of lymphangioma of the ovary after radiation due to Wilms' tumor in the childhood. The impact of this finding on the patient's fertility remains unclear. As in other organs exposed to radiation, lymphangioma can also occur in the ovary. Careful follow up should be considered to this patients, because malignant transformation can not be excluded.
