RATIONALE: Adrenocortical carcinoma (ACC) is an endocrine malignancy with poor prognosis, which commonly arises in a sporadic manner, but may also become a part of a familial syndrome. ACC rarely arises simultaneously with other malignant tumors. PATIENT CONCERNS: We report a case of a 29-year-old woman with ACC synchronously followed by an ovarian malignant mixed germ cell tumor. We describe the clinical, histopathological, and immunohistochemical findings and review the English literatures...

Dysgerminoma is one of the two most common types of ovarian germ cell tumors. Providing accurate pathologic diagnosis and treatment planning, the prognosis is good even in advanced stages. Pathologic diagnosis is generally straightforward. In microscopic examination, the usual known growth patterns in tumor cells are solid, trabecular, insular and rarely pseudoglandular. In this paper, we reported an advanced ovarian dysgerminoma with different microscopic patterns of growth, including pseudopapillary and macrofollicular structures, in an 18-year-old woman...

Increased concentrations of Anti-Muellerian hormone (AMH) can indicate a granulosa cell tumour as shown in women, mares and cows. To investigate AMH to differentiate canine granulosa cell tumour from other ovarian pathologies, we evaluated the ovaries of 63 bitches. Blood serum samples were collected before surgery for AMH analysis. Ovaries were submitted for histopathological examination. Fourteen bitches showed normal ovaries. These bitches had AMH values between 0.12 and 0.99 ng/ml. In 20 bitches ovarian cysts i...

BACKGROUND: Dysgerminoma is an uncommon malignant tumor arising from the germ cells of the ovary. Its association with pregnancy is extremely rare; the incidence is about 0.2-1 per 100,000 pregnancies. Because of its infrequency, there are few recommendations regarding its management in pregnancy; therefore, it is important to discuss and summarize the treatment strategy. CASE: We presented a case of a 23-year-old pregnant woman with a large dysgerminoma originated from the right ovary, which had the unusual coincidence of being associated with an abdominal desmoid tumor simultaneously...

BACKGROUND: In many cancers, racial and socioeconomic disparities exist regarding the extent of surgery. For ovarian dysgerminoma, fertility-sparing (FS) surgery is recommended whenever possible. The aim of this study was to investigate rates of FS versus non-fertility-sparing (NFS) procedures for stage I ovarian dysgerminoma in adolescents and young adults (AYAs) by ethnicity/race and socioeconomic status. MATERIALS AND METHODS: The National Cancer Data Base was queried for patients with ovarian dysgerminoma from 1998 to 2012...

We report the imaging findings of three ovarian dysgerminomas that coexisted with other germ cell tumors or gonadoblastomas, focusing on the distribution of tumor nests and vascular architecture, which might provide information about the pathogenesis of dysgerminomas. In a 14-year-old female with dysgerminoma and coexisting gonadoblastomas, contrast-enhanced magnetic resonance imaging (MRI) demonstrated a solid mass in the right ovary, which presented as hyperintense lobules on diffusion-weighted imaging separated by fibrovascular septa...

A 23-year-old female patient with refractory chylous ascites was successfully treated with laparoscopic ligation of the ruptured lymphatic vessel. The young patient developed abdominal distention after right-side pelvic lymph node dissection for dysgerminoma of the right ovary. Conservative managements failed to control the symptoms. Laparoscopic surgery was performed after oral administration of peanut oil, revealing the presence of a whitish fluid in the abdominal cavity. The responsible lesion of the chylous ascites was detected in the right obturator fossa and ligated with the HEM-O-LOK System (Kangji Medical Instrument Co...

METHODS: French patients (≤18years) treated for dysgerminoma between 1985 and 2005 in TGM-85, 90, 95 protocols were included. Treatment was based on primary unilateral oophorectomy followed by prophylactic lymph node irradiation (1985-1998) or a wait-and-see strategy (1998-2005) for localised completely resected tumours (pS1) or by platinum-based chemotherapy for advanced diseases. RESULTS: Forty-eight patients (median age 12.8 years) were included. Six patients had gonadal dysgenesis...

INTRODUCTION: Patients with gonadal dysgenesis (GD) with a Y chromosome have an increased risk of gonadal neoplasm. Few data exist on the ability of imaging to detect malignancy in intra-abdominal gonads in these patients. OBJECTIVE: We aimed to determine the correlation between preoperative imaging findings and gonadal pathology in GD patients with Y chromosome material. METHODS: A retrospective review was performed of patients with XY or XO/XY GD who underwent gonadectomy at our institution from 2003 to 2017...

Small cell carcinoma of ovary-hypercalcemic type is an undifferentiated carcinoma. We describe two cases in women aged 32 and 29. Both presented with large masses and complete surgical extirpation was impossible. Histologically, the images were similar, with diffuse cell proliferation, accompanied by the presence of follicle-like spaces. In both cases it was necessary to make a differential diagnosis with entities such as adult or juvenile granulosa cell tumour, small cell carcinoma of pulmonary type, dysgerminoma and even peripheral neuroectodermal tumour...

PURPOSE: In this report, we characterize the timing and behavior of malignant ovarian germ cell tumors (GCTs) in pediatric patients with dysgenetic gonads compared to those with normal gonadal development. PATIENTS AND METHODS: Patients from the Children's Oncology Group AGCT0132 with malignant ovarian GCTs were included. Within this population, we sought to identify patients with gonadoblastoma, streak ovaries, or other evidence of gonadal dysgenesis (GD). Patients with malignant GCTs containing one or more of the following histologies-yolk sac tumor, embryonal carcinoma, or choriocarcinoma-were included...

The presence of a Y chromosome in patients with Turner syndrome (TS) is a risk factor for the development of gonadal tumor and/or virilization. With conventional cytogenetic analysis, some cells containing a Y chromosome can be missed. The aim of this study was to determine the presence and incidence of Y chromosome-derived material in TS patients using PCR and the markers SRY, DYZ1, DYZ3, DYS132, ZFY, and TSPY. Fifty-five TS patients (aged 5.5-26.75 years) were analyzed. A total of 17/55 (30.9%) were Y-positive, but only 7/17 had a Y chromosome in their karyotype and underwent gonadectomy...

Gonadal dysgenesis patients with Y chromosomal material are subject to increased risk for germ cell tumors. We report a case of an adolescent female presenting with Turner-like syndrome with primary amenorrhea and Tanner stage 1 breast development. Karyotype showed one X chromosome and a minute pericentromeric fragment of Y chromosome without any functional Y genes in all the cells, unlike a mosaic pattern, represented as 46,X,der(Y)del(Y)(p11.2)del(q11.2). Laparoscopic bilateral gonadectomy was performed due to presence of Y chromosome material and histopathology confirmed gonadoblastoma with a focus of dysgerminoma of the right ovary...

Turner syndrome (TS) is an inherited genetic disorder caused by numerical and/or structural chromosome X aberrations occurring at a frequency of 1:1200-1:2500 live-born girls. The most common karyotype is X chromosome monosomy (45,X) (approximately 50-60% of cases). Approximately 5-6% of patients may have abnormal Y chromosome or mosaicism characterized by the coexistence of 45,X cell line with cell line in which all or part of chromosome Y is present. In patients with TS who have all or fragmented genetic material from chromosome Y there is a substantial risk of cancerous lesions in these dysgenetic gonads...

Swyer syndrome is a pure gonadal dysgenesis associated with a 46 XY karyotype and primary amenorrhea in a phenotypic female. Individuals in this syndrome are at an increased risk for development of gonadal malignancies. Swyer syndrome (gonadal dysgenesis) running in families is rare event and few such scenarios were reported in the literature. Here we are presenting this rare entity involving three affected siblings born to a non-consanguineous couple. Index case - A 23-year-old female with primary amenorrhea is presented with a mass per abdomen...

Yolk Sac Tumours (YSTs) of the ovary, also called Endodermal Sinus Tumours (ESTs), are the second most common Malignant Ovarian Germ Cell Tumours (MOGCTs), after dysgerminomas. YSTs occur primarily in children and young women. We present a case report of a 20-year-old woman who had been diagnosed with YST (tumour diameter of 29 cm). The patient underwent fertility sparing surgery and was subsequently treated with adjuvant chemotherapy (four cycles of bleomycin, etoposide and cisplatin). Two years after the diagnosis of YST, she successfully gave birth to a healthy girl (birth weight 3,500 g, Apgar score of 9-10 and a spontaneous vaginal delivery)...

Ovarian germ cell tumors (GCTs) are rare and affect mainly young girls and women. Two histological groups are distinguished: dysgerminomas and nondysgerminomatous tumors. These tumors have initial good responses to surgery and chemotherapy in 80% cases, but >75% of patients die due to complications of disease progression. There are very few case reports of mixed GCT with extradural spine metastases. We report a rare case of a 17-year-old girl who had undergone left salpingo-oophorectomy with omental and peritoneal biopsy for ovarian GCT with extradural spinal metastasis...

Gonadoblastomas are rare mixed gonadal tumors that are almost always found in individuals with 46, XY karyotype or some other form of Y chromosome mosaicism. It is extremely rare to diagnose gonadoblastoma in phenotypically normal 46, XX females. Herein, we present a 20-year-old 46, XX female diagnosed with gonadoblastoma and dysgerminoma. Use of cytogenetic and molecular analyses to identify the presence of Y chromosome material in peripheral blood, gonadal, and tumor tissue can exclude mosaicism to provide reassurance to undertake conservative surgical management and preserve fertility...

The purpose of this study was to determine the expression and potential clinical role of epithelial-to-mesenchymal transition (EMT)-related factors in malignant ovarian germ cell tumors (MOGCT). Protein expression of E-cadherin, N-cadherin, P-cadherin, Zeb1, HMGA2, and vimentin by immunohistochemistry was analyzed in 42 MOGCT from patients treated in Norway during the period 1981-2001. Expression was analyzed for association with clinicopathologic parameters. E-cadherin (p = 0.016) and HMGA2 (p = 0.002) expression was significantly higher in immature teratomas and yolk sac tumors compared with dysgerminomas...
