True ectopic ovary: a case and review

Introduction Ectopic ovarian tissue is a rare gynecologic problem. The nomenclature and classification systems are unclear and still debated.Case report Herein we provide a case report and review the literature to help clarify the classification system of ectopic ovarian tissue.     

Unaware of a giant serous cyst adenoma: a case report

A case of 36-year-old nonmarried virgin woman presenting a giant ovarian serous cyst adenoma weighing 9.5 kg is reported here. Ovarian neoplasms may be divided by origin cell type into three main groups: epithelial, stromal and germ cell. Taken as a group, the epithelial tumors are by far the most common type. The single most common benign ovarian neoplasm is the benign cystic teratoma; however, according to some studies it is serous cyst adenoma. A 36-year-old nonmarried virgin woman was referred to our clinic from a local medical center. When she was seen first at our outpatient clinic, she looked like a 9-month pregnant woman. Her medical history was normal. She had no serious illness or operation before. On abdominal ultrasound, a giant cyst was found which encompassed the whole abdomen. At laparotomy, a giant, totally cystic, vascularized and smooth mass attached to the right ovary was encountered, lying between the symphysis and the xiphoid. Ooferectomy was performed. On the postoperative second day, she was discharged without any problem. Her pathology report disclosed a 35×20×16 cm³ serous cyst adenoma weighing 9.5 kg. This is the largest ovarian cyst that ever reported from our hospital and one of the largest among the reported cases in the literature.     

Collision tumor: serous cystadenocarcinoma and dermoid cyst in the same ovary

Introduction  Collision tumor means the coexistence of two adjacent, but histologically distinct tumors without histologic admixture in the same tissue or organ. Collision tumors involving ovaries are extremely rare. Case  We present a case of 45-year-old parous woman with a left dermoid cyst, with unusual imaging findings, massive ascites and peritoneal carcinomatosis. The patient underwent cytoreductive surgery. The histopathology revealed a collision tumor consisting of an invasive serous cystadenocarcinoma and a dermoid cyst.     

Sclerosing stromal tumor in an accessory ovary

BACKGROUND: An accessory ovary is an uncommon congenital anomaly of the female reproductive tract. Tumors arising in ectopic ovaries are extremely rare. CASE: This 18-year-old woman had a pelvic tumor attached to the right ovary which was solid cystic and lobulated and histologically and immunohistochemically showed the appearances of sclerosing stromal tumor, a benign entity. CONCLUSION: We present the first reported case of sclerosing stromal tumor that arose in an accessory ovary.     

Ruptured Hemorrhagic Corpus Luteum Cyst in an Undescended Ovary: A Rare Cause of Acute Abdomen

BackgroundUndescended ovaries are typically detected during infertility evaluations and are frequently associated with uterine malformations. Ruptured hemorrhagic corpus luteum cyst of an undescended ovary is an unusual cause of acute abdomen in an adolescent.CaseA 15-year-old girl presented with right lower quadrant pain, nausea, and vomiting, and transabdominal sonography and magnetic resonance imaging of the pelvis showed a 10 cm × 5 cm sized cystic mass at the level of the pelvic brim, anterior to the psoas muscle suggestive of a retroperitoneal hemorrhagic cyst. At surgery, the uterus and left adnexa appeared normal, but the right ovary was not visible within the pelvic cavity, and the right pelvic retroperitoneum was distended. After opening the retroperitoneum and aspirating blood clots, the undescended ovary with a ruptured cyst was visualized within the retroperitoneum. Right ovarian wedge resection was performed and the right ovary was repositioned in the pelvic cavity.Summary and ConclusionRupture of a corpus luteum cyst in an undescended ovary should be included in the differential diagnosis of acute abdomen in adolescents.     

Supernumerary ovary on sigmoid colon resembling an endometriotic lesion

A 30-year-old woman with a history of endometriosis and chronic pelvic pain had right-sided pain and sonographic evaluation demonstrated a right ovarian cyst 5 cm in diameter. Laparotomy revealed a right ovarian cystic mass and the cystic mass was found on the sigmoid colon. After excision, histopathologic study revealed endometrioma for the ovarian cyst and a supernumerary ovary for the cystic mass on the sigmoid colon.     

Serous tumors of the ovary. I. Ultrastructural and histochemical studies of the epithelium of the benign serous neoplasms, serous cystadenoma and serous cystadenofibroma.

Histochemical and ultrastructural studies were performed on 23 benign serous neoplasms. The fine structure of the epithelium lining these neoplasms was identical to that of the fallopian tube and confirms the proposed histogenesis of these lesions from metaplasia of the celomic epithelial inclusion cysts.     

Clinical significance of N-acetyl-l-aspartate resonance in ovarian mucinous cystadenoma

Magnetic resonance spectroscopy (MRS) provides a noninvasive measurement of the biochemistry of living tissue. We report spectroscopy analysis of a 26-year-old woman affected by right ovarian lesion diagnosed as mucinous cystadenoma. MRS was performed by the point-resolved spectroscopy technique with a long echo time (TE) (136 msec). MRS measurements were performed on the two distinct component of the right ovarian tumor. The classification of metabolite peaks area in this study was performed according to the technique described by Okada et al. The features of proton MRS studies are discussed. As well as strongly elevated lactate and N-acetyl-L-aspartate signals, the tumor spectrum showed lipid resonances. Proton MRS imaging may be helpful for the investigation of the underlying pathophysiology of ovarian mucinous cystadenomas.     

Outcome of patients with one ovary in an in vitro fertilization program

To determine whether the absence of one ovary would influence adversely the outcome of in vitro fertilization, the results of 60 laparoscopic oocyte retrieval procedures in 34 single-ovary patients were compared with the outcome for all laparoscopic retrieval cycles during the same period (January 1984–August 1986) in patients with tubal infertility and two accessible ovaries (559 cycles in 335 patients). The median age was younger in the one-ovary group (31 vs 32) (P < 0.05). The group with two accessible ovaries had significantly more follicles aspirated (median, 7 vs 5; P < 0.001) and more oocytes obtained (median, 5 vs 4; P < 0.001) per retrieval compared with the single-ovary group. However, the single-ovary group had a higher percentage fertilization (69 vs 62%; P < 0.05) so that the number of embryos transferred per transfer patient (median, 3 vs 3) and pregnancy rate per cycle (9.7 vs 15.6%) did not differ significantly between groups. We conclude that patients with a single ovary have a compensatory increase in the ability to produce oocytes which may have greater potential for fertilization and subsequent development.     

Results after conservative treatment of serous borderline tumours of the ovary with stromal microinvasion but without micropapillary pattern

The aim of this study was to assess the outcomes of women treated conservatively for a serous borderline ovarian tumour with stromal microinvasion (SBOT-SMI) but without micropapillary pattern. Ten women treated conservatively for a stage I ( n = 8) or stage IIIB ( n = 2) tumour were followed up. With a median follow-up duration of 62 months (range 7–117 months), five recurrences developed on the preserved ovary. All lesions were borderline recurrences (with noninvasive peritoneal implants in one). All women are currently disease free. Three women achieved a spontaneous pregnancy and three became pregnant after an in vitro fertilisation procedure. This study suggests that conservative treatment of SBOT-SMI is safe.     

Incidental finding of an accessory ovary in a 16-year-old at laparoscopy. A case report

BACKGROUND: Supernumerary and accessory ovaries are rare anomalies. The reported incidence of these conditions is 1:29,000-700,000 gynecologic admissions. Since 1864 there have been only six cases of accessory ovary reported in the literature. Additionally, there have been 26 reported cases of supernumerary ovaries. This case seems to be the seventh reported case of an accessory ovary in over 135 years. It is the third case in a woman under age 18. In 36% of reported cases, associated congenital anomalies have been identified. Defects have included accessory fallopian tube, bifid fallopian tubes, accessory tubal ostium, bicornuate and unicorunate uteri, septate uterus, agenesis of kidney or ureter, bladder diverticulum, accessory adrenal gland and lobulated liver. CASE: A 16-year-old nulligravida complained of persistent left lower quadrant abdominal pain. Abdominal ultrasound confirmed a left ovarian cyst, which was unresponsive to medical management with oral contraceptives. At laparoscopy, a normally placed, right ovary and eutopic left ovary were identified. In addition, an accessory ovary was identified on the posterior surface of the left broad ligament. CONCLUSION: Since accessory ovaries are likely to be asymptomatic, they may be underreported. This condition is associated with a high risk of pelvic and renal anomalies and should lead to further evaluation to allow physicians to provide advice about future reproductive function and management of congenital anomalies.
