Abstract
Primary ovarian carcinoid (POC) is a very rare subset of ovarian tumors, presenting diagnostic challenges due to its inconclusive radiological imaging. In this case study, we present a 30-year-old nulliparous female with subfertility complaints and irregular menstrual cycles, who was initially misdiagnosed with an ovarian cyst. Subsequent comprehensive imaging, including Color Doppler, revealed high vascularity, and prompting suspicion of malignancy. Surgical resection and histopathological evaluation ultimately confirmed the presence of a rare Carcinoid tumor, insular type. This case emphasizes a multidisciplinary approach to the early detection and accurate diagnosis of POCs.

Abstract
Gynecological neuroendocrine neoplasms are rare entities and can be divided into two groups: carcinoids and neuroendocrine carcinomas. Due to their rarity their management is not standardized. The aim of this work is to summarize and discuss the current literature evidence on this pathology. A scoping literature review was performed in multiple databases. Thirty-one studies were included: 30 case reports and one case series. Patients' age ranged between 28 and 92 years. Surgery was the most used treatment and the surgical approach included local excision (N = 16/31; 51.6%) with (N = 5/16; 31.25%) or without (N = 11/16; 68.75%) inguinal lymphadenectomy. Adjuvant radiotherapy was delivered in 12 (38.7%) cases; instead, platinum-based therapies were frequently used when chemotherapy was chosen for adjuvant treatment. The overall survival ranged between 20 days to 4 years. However, further research is needed; currently, multimodal approach including surgery, chemotherapy and radiotherapy appeared safe and feasible for the treatment of these rare and aggressive diseases.

Abstract
Neuroendocrine carcinomas (NECs) are poorly differentiated and highly aggressive epithelial neuroendocrine neoplasms. The most common primary site is the lung, but they may arise in every organ. Approximately 37% of extrapulmonary NECs (EP-NECs) occur in the gastroenteropancreatic (GEP) tract, followed by the genitourinary (GU) system and gynecological tract. As a result of their rarity, there is scant evidence to guide treatment recommendations, and a multidisciplinary approach is essential for the management of such patients. Platinum-based chemotherapy currently represents the standard of care for EP-NECs of any site, mirroring the management of small-cell lung cancer (SCLC), but further approaches are still under investigation. Indeed, ongoing trials evaluating targeted therapies, immune checkpoint inhibitors (ICIs), and radionuclide therapy could provide potentially breakthrough therapeutic options. Given the relative dearth of evidence-based literature on these orphan diseases, the aim of this review is to provide an overview of the pathology and current treatment options, as well as to shed light on the most pressing unmet needs in the field.

Abstract
Uterine masses are commonly encountered as incidental findings during cross-sectional imaging or when individuals present with symptoms such as pain and bleeding. The World Health Organization categorizes tumors of the uterine corpus into 5 distinct groups: endometrial epithelial tumors and their precursors, tumor-like growths, mesenchymal uterine tumors, tumors with a combination of epithelial and mesenchymal elements, and various other types of tumors. The primary imaging method for assessing uterine abnormalities is transvaginal ultrasound. However, magnetic resonance imaging (MRI) can be employed to enhance the visualization of soft tissues, enabling a more detailed characterization of uterine masses. This article aims to outline the imaging features of both benign and malignant uterine masses using ultrasound, MRI, and computed tomography.

Abstract
Introduction Histologically, endometrial neuroendocrine carcinoma is an extremely rare pathological type of endometrial cancer. In addition, this type is characterized by high invasiveness and poor clinical outcome, which was classified into carcinoid (low grade), and small-cell and large-cell neuroendocrine carcinoma (high grade). Globally, reports on endometrial carcinoid carcinoma are limited. Clinically, it is also rare to see primary squamous cell carcinoma of endometrium. Case Presentation Here, we report an interesting case of mixed carcinoma of endometrium with both carcinoid and squamous cell carcinoma, which presented with persistent vaginal bleeding and hyponatremia. Conclusion Careful pathologic review is necessary to diagnose this rare disease. More studies in the future are warranted to demonstrate the primary surgical treatments and the efficacy of adjuvant therapy of this disease.

Abstract
Simple Summary Neuroendocrine refers to the cells that synthesize and secrete messenger chemicals such as neuropeptides and amines. Neuroendocrine neoplasms (NENs) are aggressive tumors arising from neuroendocrine cells, with an annual incidence of 6.98/100,000 and a prevalence of 170,000 in the United States. Primary gynecologic NENs constitute ≤2% of female reproductive tumors. NENs of the gynecologic tract are associated with high recurrence rates and dismal prognosis, making their treatment challenging. This article focuses on the updated staging classifications, clinicopathological characteristics, imaging, and management of NENs of the gynecological tract. Abstract Gynecological tract neuroendocrine neoplasms (NEN) are rare, aggressive tumors from endocrine cells derived from the neuroectoderm, neural crest, and endoderm. The primary gynecologic NENs constitute 2% of gynecologic malignancies, and the cervix is the most common site of NEN in the gynecologic tract. The updated WHO classification of gynecologic NEN is based on the Ki-67 index, mitotic index, and tumor characteristics such as necrosis, and brings more uniformity in the terminology of NENs like other disease sites. Imaging plays a crucial role in the staging, triaging, restaging, and surveillance of NENs. The expression of the somatostatin receptors on the surface of neuroendocrine cells forms the basis of increasing evaluation with functional imaging modalities using traditional and new tracers, including 68Ga-DOTA-Somatostatin Analog-PET/CT. Management of NENs involves a multidisciplinary approach. New targeted therapies could improve the paradigm of care for these rare malignancies. This article focuses on the updated staging classifications, clinicopathological characteristics, imaging, and management of gynecologic NENs of the cervix, ovary, endometrium, vagina, and vulva, emphasizing the relatively common cervical neuroendocrine carcinomas among these entities.

Abstract
BACKGROUND Primary ovarian carcinoid is a very rare ovarian low-grade neuroendocrine tumor, accounting for about 0.1% of all ovarian neoplasms. CASE PRESENTATION We reported a case of primary ovarian carcinoid arising from a mature cystic teratoma in a 50-year-old woman. Intraoperative frozen section of left ovarian mass was assessed and a malignant epithelial tumor was considered. Morphologically, the main tumor was composed of cells forming trabeculae, and mature cystic teratoma was observed adjacent to the main part. Immunohistochemistry revealed that the trabecular cells were diffuse positive for pan Cytokeratin, CD56 and synaptophysin with low Ki-67 index (about 1%). CONCLUSIONS Careful morphological observation combined with appropriate accessory examination are essential for the diagnosis of primary ovarian carcinoid arising from mature cystic teratoma. In addition, the classification criteria of the primary ovarian neuroendocrine tumor are discussed.

Abstract
PURPOSE Although rare, small-cell neuroendocrine carcinoma of the gynecologic tract (SCNCGT) is associated with poor prognosis. We analyzed the clinical characteristics, pathological features, treatment strategies, and prognosis in patients with SCNCGT. PATIENTS AND METHODS We performed a retrospective data analysis of 34 patients with SCNCGT diagnosed and treated at our hospital between 2006 and 2018. Medical records were reviewed for pathological features, treatment methods, and outcomes of this disease. RESULTS We included 34 patients who had small-cell neuroendocrine carcinoma of the endometrium (SCNCE; 7), ovary (SCNCO; 7), and cervix (SCNCC; 20). All patients with SCNCE underwent comprehensive surgery and six received postoperative chemotherapy. All patients with SCNCO received chemotherapy after surgery; six underwent comprehensive surgery and one underwent treatment only in the pelvic cavity. Sixteen patients with SCNCC underwent radical surgery and received chemotherapy, two of whom received simultaneous radiotherapy. The remaining four patients with SCNCC underwent comprehensive chemotherapy and radiation therapy. Among the 34 patients, 11 had vascular metastases, 15 had lymph node metastases, and seven exhibited positive margins. The median overall survival time among all patients was 23.18 months (range: 3-66 months). Death occurred in 18 cases (52.94%). Recurrence was observed in 13 cases (38.24%). The average time to recurrence was 15.78 months following treatment (range: 2-30 months). All 34 patients were evaluated for neuroendocrine markers. The immunohistochemical positive rates of synaptophysin, CD56, and chromogranin A were 73.5%, 64.7%, and 55.9%, respectively. CONCLUSION The rates of metastasis and recurrence are high, and prognosis remains poor, even among patients with early-stage SCNCGT. Our data may aid in the development of reference standards for diagnosis and treatment.

Abstract
Primary gynecologic neuroendocrine carcinomas (gNECs) are a heterogeneous spectrum of rare and highly aggressive neoplasms, accounting for about 2% of all gynecologic malignancies, which mostly resemble the small cell lung carcinoma (SCLC). Due to the lack of standardized treatment guidelines, their management poses a noteworthy clinical challenge. Currently, cumulative data retrieved from the management of SCLC and from retrospective studies supports a multimodality strategy, based on surgery, chemotherapy, and radiotherapy. Nevertheless, the prognosis remains poor and recurrences are extremely frequent. Hence, there is an urgent need for novel treatment options and promising molecular targets. Recently, there has been an increasing interest on the potential role of immune checkpoint inhibitors, especially in the recurrent setting. However, only scant evidence exists and there is still a long road ahead. A solid collaboration between gynecologists and oncologists worldwide is required to improve the treatment of these puzzling tumors.

Abstract
PurposePrimary ovarian neuroendocrine tumors (NETs) develop in pure form or in association with other tumors, mainly teratomas. The available data regarding this rare condition are limited. Much of the literature focuses on single case reports, previously dismissed as a totally benign disorder, and thus long-term considerations and evidence-based management guidelines are lacking. The objective of the current study was to describe the clinical and pathologic characteristics and the effect of various therapeutic modalities on patient morbidity and mortality from 2 major centers. A secondary objective was to highlight that carcinoid syndrome may be manifest in the absence of metastatic disease.MethodsThe authors retrospectively studied a cohort of 34 consecutive patients with primary ovarian NETs who attended either the Oxford University Hospitals or Beatson Oncology Centre, Glasgow, between 1984 and 2014, and had their ovarian carcinoid data (eg, tumor growth, chemotherapy regimen) and mortality outcomes assessed.ResultsAll patients were women, with an average age of 53 years (range, 23–87 years) at diagnosis. Of the 34 patients, 8 patients (23.5%) presented with carcinoid symptoms. Carcinoid heart disease was evident in 2 of the 34 patients (6%). All patients had a primary ovarian carcinoid tumor on histopathology, and 2 patients had bilateral ovarian carcinoids. Teratoma associations could be assessed in 29 tumors, with 20 (69%) of 29 showing a pathological association. The mean tumor size was 48 mm (range, 4–120 mm; SD, 40 mm). The mean follow-up was 4.5 years, ranging up to 17 years. The disease has been quiescent with no evidence of relapse in 22 of 34 patients; in 12 of 34 patients, it was metastatic. There were 5 patients who received treatment with somatostatin analogs or chemotherapy, whereas 8 patients (23.5%) died of disease. Metastatic disease was found up to 11 years from initial diagnosis.ConclusionsPrimary ovarian NET is rare and likely underrepresented in the literature. It can no longer be simply dismissed as a generally benign entity and may present with both the carcinoid syndrome and carcinoid heart disease. It requires careful evaluation and long-term review.
