Struma Ovarii with Pseudo-Meigs' Syndrome and Raised Cancer Antigen-125 Levels Masquerading as an Ovarian Carcinoma Case report and literature review.

The monodermal teratoma struma ovarii is a rare ovarian tumour; however, struma ovarii presenting with pseudo-Meigs' syndrome and raised cancer antigen (CA)-125 levels is even rarer. In elderly patients, this presentation can potentially lead to a misdiagnosis of a malignant ovarian carcinoma, resulting in unnecessary extensive surgery. We report a 55-year-old female who presented to the Lok Nayak Jai Prakash Narayan Hospital, New Delhi, India, in 2016 with progressive abdominal discomfort, fatigue and abdominal distention. Clinical and radiological features were indicative of a malignant ovarian tumour and ascites. Serum CA-125 levels were elevated at 258 U/mL. A left-sided salpingo-oophorectomy was performed, after which the serum CA-125 levels normalised. There was no evidence of recurrence at a six-month follow-up. A frozen section procedure confirmed the diagnosis of a struma ovarii. This rare condition should be considered as a differential diagnosis in patients presenting with ovarian masses, ascites and raised CA-125 levels.

Enormous ovarian fibroma with elevated Ca-125 associated with Meigs' syndrome. Presentation of a rare case.

In medicine, Meigs' syndrome is the triad of ascites, pleural effusion, and benign ovarian tumor (fibroma, Brenner tumour, and occasionally granulosa cell tumour). It resolves after the resection of the tumor. Because the transdiaphragmatic lymphatic channels are larger in diameter on the right, the pleural effusion is classically on the right side. The etiologies of the ascites and pleural effusion are poorly understood. Atypical Meigs' syndrome,characterized by a benign pelvic mass with right-sided pleural effusion but without ascites, can also occur. As in Meigs syndrome, pleural effusion resolves after removal of the pelvic mass. The authors would like to share their own experience of a case of Meigs' syndrome associated with an enormous ovarian fibroma and elevated Ca-125.

Ovary preservation in the treatment of childhood Meigs syndrome.

Meigs syndrome, the combination of benign ovarian tumor, ascites, and pleural effusion, is present in a small percentage of ovarian fibromas and is infrequently reported in children. When associated with elevated CA-125 suspicion is raised for malignancy, often prompting aggressive surgical intervention. We present a case of childhood Meigs syndrome and review the relevant literature with emphasis on ovary preservation. Out of nine identified pediatric cases, one involved ovary sparing treatment and none recurred or progressed to malignancy. Our report highlights the importance of presurgical identification of Meigs syndrome in order to curtail salpingo-oophorectomy when feasible.

Cellular leiomyoma with necrosis and mucinous degeneration presenting as pseudo-Meigs' syndrome with elevated CA125.

Pseudo-Meigs' syndrome is a syndrome rarely caused by leiomyomas. Elevated CA125 usually suggests malignancy of the ovary. No reported case of pseudo-Meigs' syndrome presenting with necrosis and mucinous degeneration of uterine cellular leiomyomas (CLs) and an elevated CA125 level was found upon a PubMed search. A 37-year-old woman presenting with massive ascites, bilateral pleural effusions and a pelvic mass measuring 20 x 18 x 10 cm is described. The pre-operative serum CA125 was 920.4 U/ml. After total abdominal hysterectomy and partial omentumectomy, the final pathologic diagnosis was CL with focal hemorrhage, necrosis and mucinous degeneration. The ascites and pleural effusion disappeared, and the CA125 level returned to normal in one month. Benign leiomyoma accompanied by pseudo-Meigs' syndrome and elevated serum CA125 can mimic a pelvic malignancy.

Meigs' syndrome with elevated serum CA 125 level in a case of ovarian fibrothecoma.

Meigs' syndrome is the association of benign ovarian tumor, pleural effusion, and ascites. Meigs' syndrome with marked elevated CA 125 is a rare clinical entity and only 42 cases have been reported. Although there is difficulty in discerning the diagnosis of Meigs' syndrome from that of an ovarian malignancy, it should be considered in the differential diagnosis in postmenopausal patients with an ovarian mass, hydrothorax, ascites, and elevated CA 125. In this report, the authors present the case of a 52-year-old postmenopausal woman with ovarian fibrothecoma, pleural effusion, ascites, and elevated CA 125 (319.2 IU/ml). Exploratory laparotomy with total hysterectomy and bilateral salpingo-oophorectomy was performed, and the pathologic diagnosis was ovarian fibrothecoma. After the surgery, the pleural effusion disappeared spontaneously and the CA 125 became normal. The authors also summarized other cases of Meigs' syndrome with elevated CA 125, and reviewed the mechanism of elevation of CA 125, ascites, and pleural effusion.

Mitotically active cellular ovarian fibroma with Meigs' syndrome and elevated CA-125: towards fertility preservation.

BACKGROUND: Meigs syndrome is rare in women under 30 years of age and even more if associated with an elevated CA-125. In this case, malignancy was suspected and raised concerns about fertility preservation. CASE: A 13-year-old girl presented with a 4-month amenorrhea, abdominal enlargement and dyspnea. Ultrasonography showed a 14-cm solid mass with ascites, bilateral pleural effusion and, analytically, elevated serum CA-125. Unilateral salpingo-oophorectomy was performed, with a 19 × 15 × 12 cm mass being disclosed from the right ovary. Final pathology diagnosed a mitotically active cellular ovarian fibroma (MACF), with no significant nuclear atypia. CONCLUSION: MACF is a recent histopathologic entity. Despite the high count of mitotic figures, it is not associated with atypia, which contributes to favorable outcome. Although initial suspicions of malignancy, a conservative surgical intervention allowed fertility preservation. This was clinically appropriate and with no implications on survival and prognosis of these patients.

Meigs' syndrome with elevated serum cancer antigen 125 levels in a case of ovarian sclerosing stromal tumor.

OBJECTIVE: Meigs' syndrome presenting as an ovarian tumor with elevated serum cancer antigen 125 (CA 125) levels is unusual. Only 37 cases have been reported, including three cases of ovarian sclerosing stromal tumor (SCT). Many reports have suggested that the presence of ascites is the major factor inducing mesothelial expression of CA 125. CASE REPORT: An 18-year-old woman presented with massive ascites, elevated serum CA 125 levels, and radiographic evidence of ovarian tumor. The histological and immunohistochemical examinations revealed a benign SCT. CONCLUSION: SCT is a benign ovarian tumor and complete excision is curative. We also review all 37 cases and discuss possible mechanisms of Meigs' syndrome and elevated serum CA 125 level.

Ascites in puerperium: a rare case of atypical pseudo-Meigs' syndrome complicating the puerperium.

PURPOSE: We report the case of puerperal ascites, associated with elevated CA125 levels and secondary to a uterine myoma. The literature on pseudo-Meigs' syndrome associated with pregnancy was reviewed. CASE: A 35-year-old woman complained of abdominal distension 2 days after a spontaneous vaginal delivery. A mass of 5 cm in the right uterine corner had been detected during the first trimester ultrasound and had been diagnosed as subserosal myoma. Physical examination and ultrasound revealed massive ascites. Computed tomography confirmed ascites and laboratory investigations showed CA125 raised levels. Cytology of ascitic fluid resulted negative for malignancy. A laparotomy was performed and a large pedunculated myoma was removed. A final diagnosis of atypical pseudo-Meigs' syndrome was performed, being computed tomography and chest X-ray negative for pleural effusion. CONCLUSIONS: To the best of our knowledge, this is the first case of pseudo-Meigs' syndrome caused by a uterine leiomyoma described in puerperium and without hydrothorax. Though ascites is very rare in obstetrics, it should be considered when evaluating puerperal patients complaining of abdominal distension.

A case of Meigs syndrome mimicking metastatic breast carcinoma.

BACKGROUND: Adnexal masses are not uncommon in patients with breast cancer. Breast cancer and ovarian malignancies are known to be associated. In patients with breast cancer and co-existing pleural effusions, ascites and adnexal masses, the probability of disseminated disease is high. Nevertheless, benign ovarian masses can mimic this clinical picture when they are associated with Meigs' syndrome making the work-up and management of these patients challenging. To our knowledge, there are no similar reports in the literature and therefore we present this case to highlight this entity. CASE PRESENTATION: A 56-year old woman presented with a 4 cm, grade 2, invasive ductal carcinoma of her left breast. Pre-treatment staging investigations showed a 13.5 cm mass in her left ovary, a small amount of ascites and a large right pleural effusion. Serum tumour markers showed a raised CA125 supporting the malignant nature of the ovarian mass. The cytology from the pleural effusion was indeterminate but thoracoscopic biopsy failed to show malignancy. The patient was strongly against mastectomy and she was commenced on neo-adjuvant Letrozole 2.5 mg daily with a view to perform breast conserving surgery. After a good response to the hormone manipulation, the patient had breast conserving surgery, axillary sampling and laparoscopic excision of the ovarian mass which was eventually found to be a benign ovarian fibroma. CONCLUSION: Despite the high probability of disseminated malignancy when an ovarian mass associated with ascites if found in a patient with a breast cancer and pleural effusion, clinicians should be aware about rare benign syndromes, like Meigs', which may mimic a similar picture and mislead the diagnosis and management plan.

Ovarian capillary hemangioma presenting as pseudo-Meigs' syndrome: a case report.

We report a case of pseudo-Meigs' syndrome, consisting of bilateral ovarian hemangiomas, hydrothorax, ascites, and an elevated CA 125 level, which was resolved after laparoscopic bilateral salpingo-oophorectomy.

Ovarian sclerosing stromal tumor presenting as Meigs' syndrome with elevated CA-125.

Meigs' syndrome caused by sclerosing stromal tumor is extremely rare and only two cases have been reported to date. An elevated serum level of CA-125 is also unusual and it has been thought that it is the consequence of physical irritation and inflammation. In this report, we present the case of a 50-year-old postmenopausal woman with a sclerosing stromal tumor presenting with Meigs' syndrome and an elevated CA-125 level (1476.8 IU/mL). This case highlights the difficulty in discerning the diagnosis of Meigs' syndrome from that of an ovarian malignancy and it should be considered in the differential diagnosis in postmenopausal patients with pelvic mass, ascites, pleural effusions and elevated serum CA-125.

Elevated CA125 level associated with Meigs' syndrome: case report and review of the literature.

Meigs' syndrome is the association of ovarian fibroma, pleural effusion, and ascites. Meigs' syndrome with marked elevation of CA125 is an unusual clinical condition reported in 27 cases in the literature. The patient was a 46-year-old woman with right pleural effusion, ascites, ovarian tumor, and CA125 level of 1808 U/mL. Tomography revealed ascites and bilobate pelvic tumor of approximately 25 cm. The diagnosis of advanced epithelial ovarian cancer was considered, and the patient was treated with chemotherapy. Three chemotherapy schemes were applied due to the total lack of response in tumor volume; however, CA125 decreased to 90 U/mL. Thus, surgery was performed with resection of 25 cm of the left ovarian tumor, with intact capsule and without implants; the result of histopathologic analysis was fibroma. Postoperative CA125 was 11 U/mL. Patients with elevated CA125 and ascites cytology positive for malignancy must be cautiously treated due to the possibility of false positives, even if the probability is low. Therefore, minimally invasive surgery for biopsy collection must be considered. Although the association between ovarian tumor, pleural effusion, ascites, and marked elevation of CA125 is highly indicative of epithelial ovarian cancer, Meigs' syndrome must be considered in the differential diagnosis.
