INTRODUCTION AND IMPORTANCE
Highly differentiated follicular carcinoma of the ovary (HDFCO) is a rare type of thyroid carcinoma originating from struma ovarii, consisting of benign-appearing thyroid follicles spread outside the ovarian tissue.
CASE PRESENTATION
We present a 22-year-old girl who underwent left salpingo-oophorectomy, omental, and peritoneal biopsies for a complex left ovarian mass. Microscopic examination and Immunohistochemical staining led to the diagnosis of HDFCO with tumor deposits affecting the omental and peritoneal biopsies. The patient was counseled about the nature of her disease and the recommended treatment. Thyroidectomy was performed later, revealing a normal thyroid gland. The patient received an ablative dose of radioactive iodine (150 mci) and a suppressive dose of levothyroxine. This is one of the youngest reported patients ever.
CLINICAL DISCUSSION
To our knowledge, the patient presented in this case report is one of the youngest patients ever reported in the literature. In the recent WHO Classification of Female Genital Tumors, the term highly differentiated follicular carcinoma arising from struma ovarii (HDFCO) was introduced, to emphasize its low-grade malignant behavior. Due to its rare incidence, there is no standard treatment strategy, but a plan based on surgical intervention is suggested.
CONCLUSION
Malignant struma ovarii should be put in the differential diagnosis in young patients with suspicious ovarian masses. Adequate patient counseling remains a cornerstone in the journey of management.

KEY CLINICAL MESSAGE
Rhabdomyosarcoma of the female genital tract often involves the vagina and cervix. It usually occurs in infants and children. Such tumors are uncommon in the uterus, especially in adults. Treatment options are based on studies of younger individuals.
ABSTRACT
Rhabdomyosarcoma (RMS) is a malignant mesenchymal neoplasm with a tendency to differentiate into skeletal muscle cells. RMS is an aggressive tumor that tends to develop in children and younger patients. A vast majority of genital tract RMSs occur in the vagina and cervix. Such tumors rarely occur in adults. Usually, these tumors either occur as a component of a biphasic uterine tumor (carcinosarcoma or adenosarcoma) or can be a pure heterologous tumor. Pure uterine RMSs are extremely rare in adult patients and difficult to diagnose. Accurate diagnosis of these tumors depends on precise histopathological evaluation. The present report describes a rare case of embryonal RMS of the uterus in a postmenopausal female and explores the most recent literature. The aim is to strengthen the existing literature and aid clinicians in the management of similar cases. A 64-year-old postmenopausal female presented with a history of abdominal pain associated with abdominal distension, per vaginal bleeding, and foul-smelling discharge for 6 months. A transabdominal ultrasound revealed a bulky uterus with a well-circumscribed heterogeneous lesion. Histopathology confirmed the diagnosis of high-grade embryonal RMS within the corpus region of the uterus. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed, followed by adjuvant chemotherapy to prevent relapse of the disease. Six months after oncological care has passed, the patient remains symptoms-free without evidence of recurrence or metastasis.

Mature teratomas, also known as ovarian dermoid cysts, are benign embryonal tumors that develop slowly. One of the following imaging techniques is commonly employed to evaluate these cysts: transvaginal ultrasound, pelvic ultrasonography, magnetic resonance imaging, or computed tomography. The two surgical methods most frequently used for removing persistent or very large cysts are laparoscopy and laparotomy. A 42-year-old female, who is P3L1D2 with a history of previous cesarean section, presented with an abdominal mass that had been gradually increasing in size over the past five months. She also reported lower abdominal pain for the last five days. Upon further evaluation, she was diagnosed with a left ovarian dermoid cyst. The patient underwent exploratory laparotomy, during which a total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. The cut section of the gross cyst specimen revealed abundant sebaceous fluid and a large tuft of hair, which was confirmed by histopathology. The patient was followed up every three months for a year. Ovarian tumors typically manifest with nonspecific symptoms. The early recognition of dermoid cysts and prompt intervention are crucial to prevent potential complications.

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.

Ovarian torsion (OT) is a gynecological emergency that can have diverse clinical presentations makings its diagnosis especially challenging. Few studies exist in the literature describing the clinical presentation as well as the management of OT in the emergency department (ED). This study aims to describe the clinical presentation, physical examination, emergency management, radiographic and intraoperative findings, histopathology reports and the time-to-intervention metrics of OT cases presenting to the emergency room of our tertiary care center. Data was collected by a retrospective chart review of all OT cases that presented to our ED over a period of 1 year. A total of 20 cases were included in the final analysis. The incidence of OT in the ED was 157.4 per 100 000 visits of women in the reproductive age group. All patients were women of reproductive age, with a mean age of 27.3 years. A total of 15 patients (78.9%) presented within 24 hours of symptom onset. The most common presenting symptom was abdominal pain (95%, 19/20) with most localizing to the right lower quadrant (60%, 12/20), followed by nausea and vomiting (90%, 18/20). Almost all patients (95%, 19/20) required opioids for pain management. The majority (80%, 16/20) were diagnosed by ultrasound prior to surgery, whereas (20%, 4/20) went straight to surgery based on a high index of clinical suspicion. Among those who underwent ultrasound, ovarian cyst was present in (75%, 12/16) while (68.9%, 11/16) showed ovarian enlargement and (50%, 8/16) showed abnormal ovarian blood flow. All patients except one patient underwent operative management. Out of the 19 patients who underwent surgery, the majority of patients (94.7%, 18/19) had viable ovaries with the exception of 1 patient (5.3%) who required a salpingo-oophorectomy post ovarian detorsion. A total of 13 cases included histopathologic review of specimens out of which 6 (46.2%) had a mature cystic teratoma. The mean time from door to ultrasonography was 1.4 hours and from door to surgery was 11.4 hours. Our study provides valuable insights into the incidence, clinical presentation, physical examination, emergency management, ultrasonographic and intraoperative findings, histopathology reports as well as the time-to-intervention metrics of OT patients presenting to the ED.

BACKGROUND
Malignant Struma Ovarii (MSO) is a rare type of germ cell tumour which is diagnosed postoperatively on surgical pathology specimens by the presence of differentiated thyroid cancer in mature cystic teratomas in the ovaries. Treatment and follow-up procedures are not clearly established due to the paucity of MSO cases. CASE 1: A 44-year-old multiparous female presented with an irregular period. Ultrasound showed a left ovarian lesion mostly a dermoid cyst, however, CT showed a 3.8 × 2.7 × 4 cm complex cystic lesion with thick septation and enhancing soft tissue component. Laparoscopic left salpingo-oophorectomy was performed and histopathology showed a follicular variant of papillary thyroid carcinoma arising in a mature cystic teratoma. Peritoneal cytology was positive for malignancy. A thyroid function test was normal before surgery. Total thyroidectomy was performed followed by radioactive (RAI) iodine therapy. Later, a total laparoscopic hysterectomy and right salpingo-oophorectomy were performed. There is no evidence of recurrent disease during the 26-months follow-up. CASE 2: A 46-year-old single female presented with left lower abdominal pain that had persisted for 2 months. Imaging revealed an 8 × 9 × 9.5 cm left ovarian mass. Laparoscopic left salpingo-oophorectomy was performed and histopathology showed mature cystic teratoma with small papillary thyroid cancer. CT showed no evidence of metastatic disease. Later, the patient had a total thyroidectomy followed by radioactive (RAI) iodine therapy. She was started on thyroxine and later had total abdominal hysterectomy and right salpingo-oophorectomy.
CONCLUSION
MSO is a very rare tumour. Preoperative diagnosis is very difficult because of the nonspecific symptoms and the lack of specific features in imaging studies. Also, there is no consensus on the optimal treatment of women with MSO. Our two cases add to the limited number of MSO cases.

Turkish Journal of Obstetrics and... Mar 2024To predict lymphovascular space invasion (LVSI) positivity in early-stage (stage 1-2) endometrial cancer (EC) using a predictive model with prognostic factors of EC.
OBJECTIVE
To predict lymphovascular space invasion (LVSI) positivity in early-stage (stage 1-2) endometrial cancer (EC) using a predictive model with prognostic factors of EC.
MATERIALS AND METHODS
We included 461 patients who underwent total hysterectomy and bilateral salpingo-oophorectomy with pelvic-paraaortic lymphadenectomy as the primary treatment for presumed early-stage EC at our clinic between 2010 and 2020. Moreover, all surgical specimens were examined histopathologically for the positivity or negativity of LVSI, and the patients were divided into two groups based on these pathologic outcomes. Age, menopausal status, histological type (type 1-2), histological grade (grades 1-2-3), depth of myometrial invasion, and peritoneal cytology results were recorded and analyzed as clinicopathological and demographic characteristics of the patients. The Loess algorithm determined the relationship between the observed and predicted outcomes. The distinction between the algorithms was evaluated by calculating the C-index.
RESULTS
LVSI positivity was significantly associated with advanced age, menopause, type 2 EC, advanced histological grade, malignant peritoneal cytology, cervical involvement, and a tumor exceeding 50% of the myometrial depth (p<0.001, respectively). Remarkably, LVSI was most strongly associated with three explanatory variables: 1- More than 50% myometrial invasion [odds ratio (OR): 3.78; 95% confidence interval (CI): 1.80-7.60], 2- Advanced histological grade [OR=1.98 (1.20-3.20) 95% CI], 3- Malignant peritoneal cytology [OR= 3.06 (1.40-6.30) 95% CI]. The penalized maximum likelihood estimation model correctly classified 87% of the included patients (C-index: 0.876).
CONCLUSION
Our predictive model may help predict LVSI based on different prognostic factors. The prognostic factors included in the nomogram were significantly associated with LVSI, particularly myometrial invasion depth of more than 50%, advanced histological grade, and malignant peritoneal cytology.

This study reports a case of uterine liposarcoma together with a literature review. At 52 years old, our patient was diagnosed with lipoleiomyoma by MRI. A mass (39 × 32 × 41 mm) protruding from the anterior wall of the uterine body was observed. When the patient was 58, her previous doctor found that the tumor had grown, and she was referred to the gynecology department of our hospital. On MRI, the major diameter was 1.23-fold longer and the volume was 1.85-fold higher compared with the prior imaging findings. Diffusion-weighted images revealed no significant anomalous signals. Thus, malignant tumors were included in the differential diagnosis. The patient consented to total abdominal hysterectomy and bilateral salpingo-oophorectomy. The mass on the anterior wall remained completely in the myometrium. No implantation was found in the abdominal cavity, and ascites was not detected. No bleeding or necrosis was observed on the cut surface. Histopathologically, differences in the sizes of adipocytes and stromal cells were identified. There were irregularities in the nuclear findings. The immunohistochemical findings were as follows: CDK4 (+), desmin (+), S100p (-), and Ki - 67 = 1%. Therefore, a diagnosis of well-differentiated liposarcoma was rendered. The lesion was localized in the uterus, and it was completely removed during surgery. Well-differentiated liposarcoma of uterine primary has no possibility of recurrence following complete resection, and thus, the patient underwent follow-up without additional treatment. No metastasis or recurrence has been observed for 10 months after surgery.

We describe an unusual presentation of a rare Leydig tumor presenting in bilateral ovaries that are otherwise normal in size for postmenopausal women. A 66-year-old woman presented with postmenopausal bleeding and during her work-up acutely developed clitoromegaly. Her diagnostic work-up revealed a 1.8 cm left ovarian complex cyst and extremely elevated testosterone levels. Management included hysterectomy and bilateral salpingo-oophorectomy. Final pathology revealed Leydig tumors in the bilateral ovaries. This case discusses a rare presentation of a rare tumor and highlights the importance of a thorough examination of the female genitalia and investigation for root cause.

Dermoid cysts are common benign ovarian tumours arising from totipotent germ cells. We report a rare case of chemical peritonitis and prolonged fever following laparoscopic salpingo-oophorectomy for torsion of a large ovarian dermoid and discuss the management of this patient with prolonged hospital stay, antibiotics and anti-inflammatory use, repeated drainage of the collection as well as re-laparotomy. The occurrence of this rare condition can be extremely distressing for the patient and treating surgeon alike, as the recommendations for management are limited. The management of chemical peritonitis may require one or more surgical procedures along with prolonged anti-inflammatory therapy.
