Pelvic mass, ascites, hydrothorax: a malignant or benign condition? Meigs syndrome with high levels of CA 125.

INTRODUCTION: Abdominal-pelvic mass, ascites and pleural effusion are suggestive of malignant metastatic ovarian cancer. This triad is also present in a rare benign condition called Meigs syndrome. Rarely this condition is associated with an increased CA 125 level. CASE REPORT: A 62-year-old woman with a history of abdominal pain underwent an ultrasound (US) examination and a chest X-ray. The imaging revealed the presence of a large pelvic mass and ascites with a monolateral pleural effusion and a high level of the tumor marker CA 125. The patient underwent a total abdominal hysterectomy, salpingoophorectomy, removal of the pelvic mass, pelvic lymphadenectomy and peritoneal biopsies. The histology showed an ovarian fibrothecoma. DISCUSSION: The US analysis according to international ovarian tumor analysis simple rules revealed "inconclusive results"; the logistic regression model LR2 and Adnex suggested a high risk of malignancy. The presence of ascites and the size of the lesion associated with a high level of CA 125 affected the correct assessment of the risk of malignancy, exposing the patient to overtreatment. CONCLUSIONS: Meigs syndrome is characterized by the resolution of symptoms after surgical removal of the pelvic mass. However, it mimics the clinical picture of a malignant metastatic ovarian cancer. Clinicians have to exclude ovarian cancer and recognize the syndrome to reduce inappropriate procedures.

The predictive role of thrombocytosis in benign, borderline and malignant ovarian tumors.

Ovarian cancer is a lethal gynecological malignancy. Although CA-125 is commonly measured in women with adnexal mass, it is estimated that it only has a positive predictive value (PPV) of 69% and a negative predictive value (NPV) of 88% for the detection of ovarian cancer. The aim of this study was to investigate the diagnostic significance and predictive impact of thrombocytosis in women with suspected or confirmed ovarian cancer. This was a retrospective study of women who had surgery for adnexal mass over a 48-month period between September 2014 and September 2018 at Swansea Gynecological Oncology Center in Wales, UK. A total of 294 women who underwent surgery for high-risk pelvic mass or biopsy-confirmed ovarian cancer were identified. 206 women (70%) had final histology confirming ovarian cancer, 54 women (18%) had benign tumors while 34 women (12%) had borderline tumors. 90/206 women (43.7%) with ovarian cancer had thrombocytosis prior to primary surgery or neoadjuvant chemotherapy compared to 8/54 (14.8%) for benign tumors and 4/34 (11.8%) for borderline tumors. Thrombocytosis was observed in 23.2%, 40%, 45.1%, and 65.1% of Stages I, II, III, and IV ovarian cancer, respectively. Thrombocytosis was a stronger predictor of ovarian malignancy in younger women of less than 60 years (p = .041). Overall, the positive likelihood ratio of platelet count in the detection of ovarian cancer was 2.61 while the negative likelihood ratio was 0.72, with a diagnostic odds ratio of 3.625. Thrombocytosis was strongly associated with advanced stage ovarian cancer (Stage III/IV) (p = .002). Interestingly, 4/8 (50%) women with thrombocytosis in the benign ovarian tumor group were diagnosed with ovarian fibroma/fibrothecoma, which often mimics advanced ovarian cancer at presentation. Predictive markers for borderline tumors continue to remain a challenge. We believe that there is a role for platelet count in primary care algorithm for women with suspected ovarian cancer. We suspect that platelets play a role in the metastasis of ovarian cancer.

Inhibin A and inhibin B producing ovarian fibrothecoma revealed by suppression of follicle stimulating hormone (FSH) in a post-menopausal woman: report of the first case.

In this report, we describe the first case ever reported in the literature, of an inhibin-A (INHA) and inhibin-B (INHB) producing fibrothecoma. A post-menopausal woman was referred to our unit because of follicle stimulating hormone (FSH) level below the reference interval for postmenopausal women. By contrast luteinizing hormone, hCG, and estradiol levels were within normal range. This discrepancy suggested the secretion of FSH inhibitory factors. INHB and INHA levels were markedly elevated for age, 475 pg/mL and 100 pg/mL, respectively. Ultrasonography and MRI showed a pelvic mass of indeterminate nature. Abnormal inhibin secretion is generally observed in granulosa cell tumors. In this case this etiology was unlikely because of low estradiol and AMH levels. Surgical exploration revealed a 10 cm mass of the left ovary proven histologically to be an ovarian fibrothecoma (OFT). After tumor removal, INHB and INHA levels decreased rapidly. Only three cases of OFT with an important secretion of INHB have been reported to date. INHA secretion has never been associated with OFT. There is a need to develop coupled hormone and imaging strategies to diagnose the source of INH secretion in case of FSH/LH discrepancy.

Meigs' syndrome with elevated CA-125 and HE-4: a case of luteinized fibrothecoma.

Presence of fibrothecoma is not usually accompanied by elevated levels of tumor markers. In recent years, however, there have been isolated reports of fibrothecoma and Meigs' syndrome, accompanied by an increase in tumor markers. We present a case of fibrothecoma with Meigs' syndrome and elevated levels of both CA-125 (cancer antigen 125) and HE-4 (human epididymis protein 4). In this paper, we present a case of Meigs' syndrome associated with an increased CA-125 and HE-4 level due to ovarian fibrothecoma.

Ovarian Fibrothecoma in a Mare-Case Report.

Ovarian tumors in mares are uncommon in comparison to other neoplasms and are classified into three categories: gonadal stromal tumors, coelomic epithelium surface tumors, and germinal cell tumors. Some ovarian neoplasms histologically show a mixture of multiple cell types in the same tumor, such as fibrothecoma; therefore, the differentiation between fibroma and thecoma is often difficult. According to the World Health Organization, fibrothecomas are classified as sex-cord stromal tumors (pure stromal tumors). Neoplasms such as fibrothecoma present with limited morphological, clinical, ultrasonographic, and endocrine profile characteristics. To diagnose this type of tumor, a broad clinical examination is needed, but histopathology remains the most accurate. Herein, we report a case of incidentally found ovarian fibrothecoma during a diagnostic laparotomy in a 6-year-old Dutch Warmblood (KWPN) mare who presented to the clinic with colic symptoms. After a unilateral ovariectomy, the altered right ovary was diagnosed as fibrothecoma based on histopathological features.

Fibrothecoma a rare ovarian tumor: A case report.

INTRODUCTION AND IMPORTANCE: Fibroma, thecoma, and fibrothecoma collectively denote a range of non-cancerous sex cord-stromal tumors distinguished by the presence of fibroblastic stromal cells and/or cells resembling luteinized theca cells. CASE PRESENTATION: In this report, we present a case study of a 52-year-old patient in whom this uncommon tumor was identified via MRI, highlighting the distinctive diagnostic and treatment considerations associated with it. CLINICAL DISCUSSION: Ovarian fibrothecoma tumors are infrequent, constituting less than 4 % of all ovarian tumors. Although they may manifest at any age, they are more commonly observed in elderly and post-menopausal individuals. Diagnosis hinges on clinical and paraclinical data, yet definitive confirmation is predominantly achieved through anatomopathological examination. For younger patients, conservative surgery is usually favored, whereas peri- or post-menopausal individuals may undergo radical treatment. CONCLUSION: Ovarian Fibrothecoma, though rare, are typically benign tumors frequently found in older patients. Diagnosis primarily relies on histological examination. Fortunately, the prognosis for these tumors is generally favorable.

A Case Report: Ovarian Fibrothecoma with Minor Sex Cord Elements.

Introduction: Ovarian stromal tumors with minor sex cord elements are rare, and there are not specific imaging features to help in making the diagnosis. Case Presentation: We report a case of this tumor in an 81-year-old woman who was referred to our hospital for constipation and a pelvic mass. Magnetic resonance imaging demonstrated a well-circumscribed mass and isointensity compared to the skeletal muscle on T1-weighted imaging (T1WI) and low signal intensity mixed with high signal ranges on T2-weighted imaging. Dynamic gadolinium-enhanced fat-suppressed T1WI revealed mild and increased enhancement of the peripheral area in the early and delayed phases, respectively. On diffusion-weighted imaging (DWI), a heterogeneously high signal intensity corresponding to the peripheral enhanced area was observed, and the apparent diffusion coefficient values of the high-intensity areas on DWI were low. Malignancy could be suspected, so the mass was surgically removed. Pathological assessment revealed a fibrothecoma with minor sex cord elements. Conclusion: The tumor's preoperative diagnosis is difficult, although the possibility of this rare tumor from atypical findings on DWI and/or dynamic contrast enhancement studies should be considered.

Challenging diagnoses in a case report: Ovarian fibrothecoma with elevated CA125 levels mimicking malignancy.

INTRODUCTION AND IMPORTANCE: Ovarian fibromas are benign tumours arising from the connective tissue of the ovarian cortex, classified into three pathological subtypes: fibroma, thecoma, and fibrothecoma. Their diagnosis is complicated by their solid nature and potential association with ascites and pleural effusion, resembling Meigs syndrome. Elevated serum CA125 levels can further complicate differentiation from malignant ovarian epithelial tumours. CASE PRESENTATION: A 37-year-old female from a rural area presented with a distended abdomen and weight loss lasting 2 months. Clinical examinations revealed a solid pelvic mass and diagnostic tests showed significantly elevated CA125 levels. Imaging suggested a large ovarian mass and surgical intervention confirmed a fibrothecoma of the left ovary. The postoperative course was uneventful, with subsequent resolution of ascites and pleurisy. CLINICAL DISCUSSION: The diagnosis of ovarian fibromas/fibrothecomas poses challenges due to their asymptomatic nature, solid appearance, and occasional association with the Meigs syndrome. Elevated CA125 levels can mislead the diagnosis of epithelial ovarian carcinoma. The case underscores the importance of considering ovarian fibromas/fibrothecomas in the differential diagnosis of ovarian tumours with elevated CA125 levels, especially in women of reproductive age. The benign nature of these tumours necessitates a conservative surgical approach, emphasizing the importance of intraoperative frozen section analysis. CONCLUSION: Ovarian fibrothecomas associated with elevated serum CA125 levels are rare. Their presentation can mimic malignant ovarian neoplasms, leading to potential diagnostic confusion. Surgical removal remains the treatment of choice, with a favorable prognosis post-surgery.

A Case Report of Meigs' Syndrome Caused by Ovarian Fibrothecoma with High Levels of CA125.

Purpose: Meigs' syndrome is a rare gynecological disease characterized by the triad of benign ovarian tumor, ascites, and pleural effusion. Ovarian malignancies should be highly suspected in a postmenopausal woman with a pelvic mass, ascites, hydrothorax, and an elevated carbohydrate antigen 125 (CA125) level. It can be challenging to make a preoperative diagnosis of Meigs' syndrome. In this report, we present a case of Meigs' syndrome caused by an ovarian fibrothecoma and review the relevant literature to raise awareness and avoid misdiagnosis. Case Presentation: An 82-year-old woman with a 2-week history of abdominal distension was admitted to the Department of Gynecology. Ultrasound and thoracoabdominal computed tomography scans showed a left-sided hypoechoic mass in the pelvic cavity with bilateral pleural effusion and massive ascites. The CA125 concentration was 1040 U/mL (normal, 0-35 U/mL). With a working diagnosis of ovarian malignancy, the patient underwent ultrasound-guided fine-needle puncture of the pelvic mass and paracentesis to drain the ascites. The fine-needle puncture and paracentesis fluid analysis results revealed that the ascites did not contain any tumor cells, and the pelvic mass was identified as a spindle cell tumor. Immunohistochemistry confirmed that it was a sex-cord stromal tumor. Total abdominal hysterectomy and bilateral adnexectomy were performed under general anesthesia. The pathology results confirmed the mass to have been an ovarian fibrothecoma. At the 2-month postoperative follow-up, the ascites and hydrothorax had resolved and not recurred, and the CA125 level was normal. Conclusion: Despite the high suspicion of ovarian carcinoma in postmenopausal women presenting with pelvic mass, ascites, pleural effusion, and elevated CA125, Meigs' syndrome should be considered.

A Rare Case of Hyperandrogenism Due to Fibrothecoma and Leydig Cell Tumor in a Postmenopausal Woman With Adrenal Adenoma: A Case Report and Literature Review.

Hyperandrogenism is an endocrine disorder characterized by an elevated level of androgen in women, which can be due to several etiologies, including ovarian and adrenal causes. Hyperandrogenism can result in hirsutism and virilization in severe cases. Ovarian etiologies can include ovarian hyperthecosis, hilus cell tumors, arrhenoblastomas, and Leydig cell tumors. Diagnosing the specific cause requires comprehensive work, and management is then tailored to address the specific etiology. Treatment may include bilateral oophorectomy and gonadotropin-releasing hormone (GnRH) analogs in combination with antiandrogen therapy. Surgery, medical treatment, and radiation therapy are also options for patients with hypercortisolemia. We present the case of a 58-year-old female who presented with clinical features of hyperandrogenism, which were confirmed with biochemical testing. She was found to have a non-functioning adrenal adenoma with no significant abnormality on ovarian imaging and biochemical hyperandrogenemia due to fibrothecoma and Leydig cell tumor, which resolved after bilateral salpingo-oophorectomy.

A case report of bilateral benign Ovarian Fibrothecoma coincidental with ascites: an unconventional co-occurrence.

Ovarian fibrothecoma are a mostly benign and profoundly rare type of gonadal stromal cell tumor. It makes up 3-4% of all kinds of ovarian neoplasia. They are predominantly unilateral in origin and mostly present in women during the postmenopausal phase. Our case is especially important because the tumors occurred bilaterally and were associated with ascites. This seldom happens in patients with ovarian fibrothecoma. Early identification and treatment are key components to avoid the subsequent complications of this tumor. Case presentation: We present the case of a 54-year-old female who presented complaining only of a slow progressive increase in the abdominal contour associated with vague abdominal pain. Our preoperative radiological imaging revealed multiple ovarian and uterine masses. Clinical discussion: Surgical intervention in the form of a hysterectomy with bilateral salpingo-oophorectomy was achieved. Histopathological analysis revealed bilateral benign ovarian fibrothecoma with benign uterine leiomyomas. The patient underwent an uneventful postoperative recovery. Conclusion: Ovarian Fibrothecoma is a rare gynecological pathology. The uniqueness of our case stems from the rarity of its bilateral occurrence and in rare occasions, their occurrence is accompanied by ascites. This kind of co-occurrence should be differentiated from other rare presentations, such as Meigs Syndrome. Therefore, documentation is necessary to circumvent misdiagnoses and to abate the resulting patient morbidity. To further highlight the value of our case, it is to the best of our knowledge, the first documented case of this pathology from our country.

A Rare Case of Collision Tumours of the Ovary: An Ovarian Serous Cystadenoma Coexisting with Fibrothecoma.

The incidence of epithelial tumours of the ovary ranges from 9-17 per 100,000 and is the highest in high-income countries, with the exception of the Japan. The coexistence of neoplastic Müllerian epithelial and sex cord-stromal elements within a single tumour is extremely rare. We describe the case of a 74-year-old woman with a voluminous left adnexal formation. Pre-operative assessment with ultrasound evaluation made a suspicious diagnosis of benignity of the lesion. Bilateral salpingo-ovariectomy was performed. Intraoperative frozen section analysis results in the diagnosis of fibrothecoma in the context of serous cystadenoma. The diagnosis is confirmed by histological examination. Some authors suggest labelling this phenomenon as collision tumours.

A 40-year-old man with a rapidly growing intrascrotal tumor in the fibroma-thecoma group.

Introduction: Tumors in the fibroma-thecoma group are benign tumors, typically found in the ovaries of postmenopausal women and occasionally develop in the testes. These tumors are mostly treated with radical orchiectomy because preoperative diagnosis confirming the benign nature is difficult. Case presentation: A 40-year-old man was incidentally pointed out to have a right intrascrotal mass, measuring approximately 10 cm on computed tomography. Malignant testicular tumor was suspected based on the location and size of the tumor. The patient underwent right radical orchiectomy. Histologically, the tumor had no evidence of malignancy, and the diagnosis of tumors in the fibroma-thecoma group was made. The patient had no recurrence 8 months after surgery. Conclusion: Intrascrotal tumors in the fibroma-thecoma group are rare benign tumors and mostly treated with radical orchiectomy due to concerns about malignancies. Further investigation is needed for accurate preoperative diagnosis, and we should be aware of these rare tumors.

The Value of MRI Findings Combined With Texture Analysis in the Differential Diagnosis of Primary Ovarian Granulosa Cell Tumors and Ovarian Thecoma-Fibrothecoma.

OBJECTIVE: This study aims to explore the value of magnetic resonance imaging (MRI) and texture analysis (TA) in the differential diagnosis of ovarian granulosa cell tumors (OGCTs) and thecoma-fibrothecoma (OTCA-FTCA). METHODS: The preoperative MRI data of 32 patients with OTCA-FTCA and 14 patients with OGCTs, confirmed by pathological examination between June 2013 and August 2020, were retrospectively analyzed. The texture data of three-dimensional MRI scans based on T2-weighted imaging and clinical and conventional MRI features were analyzed and compared between tumor types. The Mann-Whitney U-test, χ 2 test/Fisher exact test, and multivariate logistic regression analysis were used to identify differences between the OTCA-FTCA and OGCTs groups. A regression model was established by using binary logistic regression analysis, and receiver operating characteristic curve analysis was carried out to evaluate diagnostic efficiency. RESULTS: A multivariate analysis of the imaging-based features combined with TA revealed that intratumoral hemorrhage (OR = 0.037), log-sigma-20mm-3D_glszm_SmallAreaEmphasis (OR = 4.40), and log-sigma-2-0mm-3D_glszm_SmallAreaHighGrayLevelEmphasis (OR = 1.034) were independent features for discriminating between OGCTs and OTCA-FTCA (P < 0.05). An imaging-based diagnosis model, TA-based model, and combination model were established. The areas under the curve of the three models in predicting OGCTs and OTCA-FTCA were 0.935, 0.944, and 0.969, respectively; the sensitivities were 93.75, 93.75, and 96.87%, respectively; and the specificities were 85.71, 92.86, and 92.86%, respectively. The DeLong test indicated that the combination model had the highest predictive efficiency (P < 0.05), with no significant difference among the three models in differentiating between OGCTs and OTCA-FTCA (P > 0.05). CONCLUSIONS: Compared with OTCA-FTCA, intratumoral hemorrhage may be characteristic MR imaging features with OGCTs. Texture features can reflect the microheterogeneity of OGCTs and OTCA-FTCA. MRI signs and texture features can help differentiate between OGCTs and OTCA-FTCA and provide a more comprehensive and accurate basis for clinical treatment.

Triple negative lobular breast carcinoma metastatic to an ovarian fibrothecoma.

A postmenopausal woman with lobular breast carcinoma metastatic to a large ovarian fibrothecoma is presented. The two metastatic tumor nodules were grossly subtle and could have been overlooked in the background of the large ovarian stromal tumor. Thorough sampling of the tumor for histologic examination and supporting immunohistochemical stains were important in establishing the diagnosis. Differential diagnostic considerations are discussed.

A presentation of ovarian fibrothecoma in a middle-aged female with recurrent massive ascites and postmenopausal bleeding: A case report.

Fibrothecomas are mostly benign ovarian tumors. We describe a rare case of fibrothecoma in a 59-year-old woman with a history of recurrent massive ascites and postmenopausal bleeding. Over 2 years she has undergone more than 50 paracenteses with 8-11 L withdrawn each time. She presented with a newly diagnosed pelvic mass and bilateral hydrosalpinges demonstrated on ultrasound and were confirmed with computed tomography. The pelvic magnetic resonance imaging showed a large complex cystic mass arising from the left ovary measuring 16.6 × 12.1 × 8.6 cm3 with an area of irregular mural enhancement. The patient underwent left salpingo-oophorectomy with benign frozen section results. The final pathology was consistent with cystic degeneration of fibrothecoma.

Testicular fibrothecoma: A case report and literature review.

Sex cord Stromal are neoplasms containing granulosa, Sertoli, and Leydig cells. The problem usually occurs among females that are hormonally active and is associated to Gorlin-Goltz syndrome. The present study reports a 37-year-old male was referred to Urologist due to a firm right testicular mass for which orchiectomy was performed. Tumor markers were all within normal range. Histopathological examination revealed compact spindle tumor involving the rete-testis in keeping with pure fibrothecoma. The results of the given study are valuable for medical professionals related to the field of urology and pathology.

A rare case of Meigs syndrome in pregnancy.

We present a case of Meigs syndrome in a 19 year old woman. We suspected metastatic ovarian cancer after she had presented in her first pregnancy at 12 weeks gestation. Ultrasound scan had confirmed a complex solid mass in the left adnexa, measuring 7cm x 8cm, a viable 12 weeks pregnancy and gross ascites. She had elevated Ca 125 and serum beta - HCG. She went on to have a spontaneous miscarriage while being worked up for exploratory laparotomy. At laparotomy, a left sided solid ovarian mass 8cm x 10cm with a smooth surface and intact capsule was found. This was later confirmed to be a fibrothecoma at histology. The patient went on to recover without any further reaccumulation of ascites.

A rare presentation of ovarian fibrothecoma in a middle age female: case report.

Fibromas/fibrothecomas are considered to be benign ovarian tumors. We describe a rare case of recurrent fibrothecoma with a clinically malignant course. A 42-year-old woman, with no family history of malignancy, operated multiple times for tumor that recurred three times within 4 years despite radical surgical removal. Initially, she presented with 9×7×10 cm right ovarian mass, frozen section was consistent with fibrothecoma and thus right salpingoophorectomy was performed. At the last two recurrences, she was found to have recurrent multiple abdominopelvic fibrothecomas and two long major operations were performed. This malignant behavior of a benign tumor is very rare. Further genetic analysis and immunohistochemistry studies are recommended to be conducted. Furthermore, new modalities of treatment should be considered, eg, high-intensity focused ultrasound and/or hormonal treatment.
