Abstract
Malignant struma ovarii (MSO) with synchronous primary thyroid cancer in the neck is extremely rare and lacks a treatment consensus. A 44-year-old woman presenting with a left ovarian cyst was admitted to Peking Union Medical College Hospital (Beijing, China) Ultrasonography showed a 6 cm solid-cystic left ovarian mass with plentiful blood signals. Other notable findings were an elevated CA125 level and a suspected malignant thyroid nodule. A unilateral salpingo-oophorectomy (USO) was conducted, and the surgical pathology was papillary thyroid cancer (PTC) arising in a struma ovarii. The patient underwent a total thyroidectomy and cervical lymph node dissection, and the pathology of the right lobe nodule was follicular-variant PTC without capsule invasion or lymph node metastasis (5 mm; pT1aN0M0). No further adjuvant therapy was administered. The serum thyroglobulin value was normal before surgery and was undetectable after thyroidectomy. During regular follow-up examinations over 4 years, the patient remained well with no evidence of disease (NED). In a literature review, another 13 cases of MSO coexisting with cervical thyroid cancer that had reported outcomes were found. The MSO was confined to the ovary in all cases. A total of nine patients received radioiodine therapy (RAI) treatment after total thyroidectomy. Two patients relapsed and were successfully cured with RAI after the initial surgery Only one patient died due to another disease, while 11 patients showed NED and the remaining patient was alive with the disease after a median follow-up time of 2 years. This data suggests that USO with personalized RAI may be a preferred option for MSO confined to the ovary plus synchronous primary thyroid cancer due to the conferred satisfactory prognosis.

RET/PTC rearrangement in papillary thyroid carcinoma arising in malignant struma ovarii with abdominal wall metastasis and cervical thyroid gland: a case report and review of the literature. Thyroid Res 2023; 16:39. [PMID: 37759238 PMCID: PMC10537935 DOI: 10.1186/s13044-023-00181-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Accepted: 08/24/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND Struma ovarii refers to rare mature cystic teratomas containing at least 50% of thyroid tissue, and malignant transformation is known to be even rarer. The synchronous development of malignant struma ovarii and cervical thyroid carcinoma are also scarce and poorly understood due to limited data about molecular features. Here, we present the first report of RET/PTC 1 rearrangement in synchronous metastatic malignant struma ovarii to the abdominal wall and cervical thyroid cancer. CASE PRESENTATION We described a 47-year-old multigravida woman with bilateral adnexal and lower abdominal wall masses detected during the evaluation of abnormal uterine bleeding. The patient underwent a hysterectomy, bilateral salpingo-oophorectomy, and surgical removal of abdominal wall mass. Then, the pathological evaluation revealed papillary thyroid carcinoma (PTC) within struma ovarii and metastatic PTC in the abdominal wall fibro adipose tissue. Further, cervical thyroid gland physical examination and ultrasound illustrated a nodule within the left lobe. Subsequently, a total thyroidectomy was performed, and a histological examination revealed PTC. Furthermore, all affected tissue, i.e., struma ovarii, abdominal wall metastasis, and cervical thyroid gland tested for BRAF and RAS mutations and RET/PTC 1 rearrangement. RET/PTC 1 rearrangement was identified among all three different sites. Finally, after six years of follow-up, the patient had no evidence of recurrence or distant metastasis. CONCLUSIONS In light of these findings, malignant struma ovarii might yield a clue to cervical thyroid carcinoma, and the molecular analysis could provide valuable information for understanding the underlying mechanism, tumor clinicopathological behaviors, and prognosis.

Abstract
Ovarian tumors can be classified by their origin - epithelial tumors, germ cell tumors, and stromal tumors. Malignant struma ovarii (MSO) are 0.01% of all ovarian tumors. In order to be classified as a struma ovarii, more than 50% of the teratoma consists of thyroid tissue. The thyroid tissue in the struma ovarii exhibits the same histological and physiological properties as that of the cervical thyroid tissue. Poorly differentiated thyroid carcinoma (PDTC) is an extremely rare occurrence when arising from an MSO. Including this case report, there are only 10 reports of PDTC in the setting of MSO. Of these cases, this patient is the only one who presented with concurrent primary thyroid carcinoma (PTC). This case study examines how invaluable intra-professional collaboration is for appropriate diagnosis, along with attention to detail of identifying markers in pathology sections and use of the appropriate immunohistochemical analysis.

Abstract
BACKGROUND Struma ovarii is an unusual ovarian teratoma containing predominantly thyroid tissue. Less than 10% of cases undergo malignant transformation in the thyroid tissue and are considered malignant struma ovarii (MSO). MSO have been reported with concurrent thyroid lesions, but molecular data is lacking. CASE PRESENTATION A 42-year-old female developed MSO and synchronous multifocal subcentimeter papillary thyroid carcinoma (PTC). The patient underwent a salpingo-oophrectomy, thyroidectomy, and low-dose radioactive iodine ablation. Both the thyroid subcentimeter PTC and MSO were positive for BRAF V600E mutation, and microRNA expression profiles were similar across all tumor deposits. However, only the malignant component demonstrated extensive loss of heterozygosity (LOH) involving multiple tumor suppressor gene (TSG) chromosomal loci. CONCLUSIONS We present the first reported case of MSO with synchronous multifocal subcentimeter PTC in the thyroid containing concordant BRAF V600E mutations and resulting with discordant LOH findings. This data suggests that loss of expression in tumor suppressor gene(s) may be an important contributor to phenotypic expression of malignancy.

Abstract
AIM To evaluate the clinico-pathologic features, treatment options, prognostic factors, and survival outcomes of malignant struma ovarii based on a systematic literature review in association with our case study. METHODS A systematic review of the medical literature was performed to identify articles about malignant struma ovarii from January 1983 until July 2020. We evaluated 178 cases. RESULTS The 5-year progression-free survival (PFS) and overall survival (OS) of the entire cohort was 72.5% and 91%, respectively. In univariate analysis, younger age (<43 years), whole strumal cyst diameter >95 mm, presence of a histologic type other than papillary classic-type thyroid carcinoma within the tumor and lymphovascular space invasion were related to poor PFS. Patients who received radioactive iodine ablation (RIA) before the treatment failure had significantly higher PFS than those who did not receive RIA (94.9% vs. 64.8%, p = 0.041, respectively). In univariate analysis, PFS was significantly higher in patients who underwent gynecologic surgery followed by thyroidectomy and RIA compared with those who had surgical treatment only (94.5% vs. 64.3%, p = 0.05, respectively). However, this result could not be identified as an independent prognostic factor in multivariate analysis (p = 0.207). Younger age and absence of capsular involvement were related to significantly increased OS. Histologic type was the only independent prognostic factor for PFS (hazard ratio: 3.30, 95% confidence interval: 1.122-9.748; p = 0.030) CONCLUSION: The most common histologic subtype was the papillary classic type. The presence of a histologic type other than the classic papillary thyroid carcinoma within the tumor was an independent adverse prognostic factor.

Abstract
Struma Ovarii is one of the types of mature teratoma, with predominant thyroid tissue (>50%). It occurs in 1% of all cases of ovarian tumors and in 2.7% of dermoid tumors. There are no specific clinical, radiological or serum markers for this rare pathology. Rarely it may be accompanied by ascites and the increased level of CA-125. In general Stuma Ovarii is clinically defined as an ovarian malignancy. It is diagnosed only by histopathological examination of the surgical material. Diagnosis of Struma Ovarii dictates the need for advanced research of the thyroid. Struma Ovarii is mostly benign. Its malignant transformation occurs in only 5% of all cases, That leads to further management planning analogous to the treatment of thyroid cancer. The case of malignant Struma Ovarii of the 50-year-old woman, which led to total thyroidectomy and radioactive iodine therapy - is described.

Abstract
Papillary thyroid carcinoma (PTC) arising in a coexistent struma ovarii (SO) is a rare malignancy. It manifests with abdominal symptoms such as palpable mass, pain, distension, and possibly ascites. It is usually diagnosed postoperatively, and its histopathological diagnostic criteria remain identical to that of papillary carcinoma of the thyroid gland. Due to the relative rarity of the disease, definitive guidelines for its overall management are still undefined. We present a case of a 51-year old female with suspicion of a left ovarian tumor due to her presenting symptoms: raised serum CA-125 levels and abnormal abdominopelvic CT scan findings. She underwent complete surgical debulking of the mass (total abdominal hysterectomy (TAH), bilateral salpingo-oophorectomy (BSO), omentectomy, appendectomy, and pelvic lymphadenectomy). The mass was postoperatively diagnosed by histopathology as PTC in SO (stage IA). Furthermore, our patient did not receive any adjuvant treatment. The patient has been disease-free for 24 months post-surgery and is scheduled for regular biannual follow-ups.

Abstract
Objective To present a rare case of malignant struma ovarii (MSO) and synchronous thyroid cancer, review the medical literature, and present the latest trends in management. Methods The case of a woman with MSO and concomitant thyroid cancer is presented, including clinical presentation, treatment, and follow-up care. A search of the English-language literature was conducted using MEDLINE and Google Scholar data bases. Results We found 10 publications (one abstract) describing 10 patients with MSO and concomitant thyroid cancer. Six additional patients were reported by a study that analyzed the SEER (cancer registry) database. The median age of women was 42 years, with the majority of them presenting with abdominal symptoms. Histologically, most tumors were papillary carcinomas in both organs. In 5 patients, there was extrathyroidal tumor extension at time of surgery. Conclusion MSO can occasionally coexist with highly aggressive eutopic thyroid cancer. Although this concurrence is even rarer than MSO, clinicians should routinely investigate for possible synchronous thyroid cancer in all cases of MSO and also consider aggressive postoperative treatment including thyroidectomy and radioiodine ablation therapy in cases of MSO.

Abstract
Struma ovarii is an ovarian tumor with thyroid tissue as its predominant component. Most patients are euthyroid, but some reports have noted thyrotoxicosis originating from the malignant struma ovarii. Papillary thyroid carcinoma was reported as the soul mass of struma ovarii in our patient. Struma ovarii should be a possible diagnosis in female patients with thyrotoxicosis manifestations with normal thyroid scan and examination.
Introduction Struma ovarii is an ovarian tumor with thyroid tissue as its predominant component. It usually occurs in older women and presents with abdominal mass, pain and abnormal bleeding. Most patients are euthyroid, but some reports have noted thyrotoxicosis originating from the malignant struma ovarii. Presentation of case A 10 year-old girl presented with tachycardia, normal thyroid exam and thyrotoxicosis. Thyroid scan showed no uptake with increased uptake in right ovary indicative of struma ovarii. The patient underwent oophorectomy and thyroidectomy, Pathology showed papillary thyroid carcinoma limited to the struma ovarii. Following TSH suppressive therapy and treatment with I131, she is totally symptom free. Discussion Struma ovarii should be a possible diagnosis in any female patient with thyrotoxicosis manifestations with normal thyroid scan and examination.

Abstract
Background Malignant struma ovarii (MSO) is a very rare, germ cell tumor of the ovary, histologically identical to differentiated thyroid cancers. Struma ovarii (SO) is difficult to diagnose on clinical basis or imaging and is mostly discovered incidentally, with few published cases in the literature. Case presentation A 42-year old primiparous woman presented with abdominal pain and midline pelvic palpable firm mass arising from the pelvis. Imaging showed pelvic solid cystic mass. Total abdominal hysterectomy, bilateral salpingo-oopherectomy (TAH BSO) and infracolic omentectomy were performed. Histopathology revealed left ovary papillary thyroid carcinoma (PTC) arising in SO (11 cm) and metastatic papillary thyroid carcinoma in the right ovary. Thyroid functions tests were all normal, ultrasound thyroid showed two complex nodules in the left thyroid lobe. Total thyroidectomy was decided, but the patient refused further surgical management and was lost to follow up as she left the country. We undertook a comprehensive literature search, and MSO and thyroid management data from 23 additional publications were analyzed and tabulated. This PTC MSO is probably the largest reported in the literature. Conclusions Among the different surgeries for MSO, TAH + BSO appears to have the best clinical outcome. However, unilateral salpingo-oopherectomy/ unilateral oophorectomy and bilateral salpingo-oopherectomy also seem effective. Ovarian cystectomy alone seems associated with higher recurrence. There remains no consensus on the associations between MSO tumor size and potential extent of metastasis, and about the management of thyroid gland. However, surveillance and thyroid gland work up to detect concurrent thyroid cancer are recommended.
