Abstract
Both male and female reproductive functions are impacted by altered gonadotrophin secretion and action, which may also influence the development of endocrine tumours. To ascertain if chronic hypersecretion of human chorionic gonadotropin (hCG) contributes to the development of gonadal tumours, double transgenic (TG) mice that overexpress hCGα- and β-subunits were analysed. By the age of two months, ovarian tumours with characteristics of teratomas developed with 100% penetrance. Teratomas were also seen in wild-type ovaries orthotopically transplanted into TG mice, demonstrating an endocrine/paracrine mechanism for the hCG-induced ovarian tumorigenesis. Both in vitro and in vivo experiments showed oocyte parthenogenetic activation in TG females. In addition, ovaries showed reduced ovulatory gene expression, inhibited ERK1/2 phosphorylation, and impaired cumulus cell expansion. Hence, persistently high endocrine hCG activity causes parthenogenetic activation and development of ovarian teratomas, along with altered follicle development and impaired ERK1/2 signalling, offering a novel mechanism associated with the molecular pathogenesis of ovarian teratomas.

Abstract
BACKGROUND Ovarian neoplasms in children are rare heterogeneous lesions with variable biological behaviour and outcome. We herein report a 25-year experience from a UK specialist centre managing paediatric ovarian tumours. METHODS All female patients requiring operation for ovarian tumours were identified during the study period 1990-2018. Patient demographics, clinical presentation, and management are highlighted. RESULTS Eighty-eight females with 101 ovarian tumours including cases with synchronous and metachronous neoplasms were documented. Mean age at diagnosis was 11.8 years. Tumours were equally distributed in left and right ovary(s). Bilateral disease occurred in 11 (10.8%) patients. Eighty-six (85%) neoplasms were benign and 15 (15%) malignant requiring in addition to surgery chemotherapy and/or radiation. There were no significant difference(s) observed in maximum tumour diameter in benign vs malignant lesions. Only half of malignant tumours had positive tumour markers. Fifteen patients (15%) had ovarian lesions that were metastatic at primary presentation including a rare case of disseminated peritoneal gliomatosis. Surgical management included salpingo-oopherectomy n = 21 (21%), ovary excision n = 33 (33%), 'ovary sparing' tumourectomy n = 34 (34%), and cyto-reductive extirpation in 2 cases (2%). Lymphadenectomy was performed in 9 patients (9%) together with peritoneal fluid cytology in 18 cases (18%) who had abdominal ascites. Omentectomy was required in 14 patients (14%), multiple peritoneal biopsy(s)-in 11 cases (11%) and biopsy of other suspicious involved organs notably bowel, gut mesentery and contralateral ovary in 7 (7%) further patients. Recurrent and metachronous lesions occurred in 10 (10%) cases in those with teratoma (n = 9) and adenocarcinoma(s) (n = 1). Overall patient survival was 97% with only 3 deaths-mucinous cystadenocarcinoma (n = 1), desmoplastic small round cell tumour of ovarian origin (n = 1), and a small cell carcinoma of ovary with hypercalcaemia (n = 1). CONCLUSIONS Findings from this study show an excellent survival (97%) for paediatric ovarian neoplasms. Rare malignant neoplasms though do carry a poor prognosis. In the modern era of care, all efforts should be made to preserve future hormonal health and fertility with 'ovarian sparing' operation(s) where appropriate.

Abstract
CASE REPORT A healthy 57-year-old woman presented with decreased vision in her right eye. Dilated fundus examination revealed central retinal vein occlusion (CRVO). The laboratory test results for hypercoagulability state showed an abnormal protein S. A few months later she developed an ovarian malignancy. DISCUSSION This case illustrates an association between CRVO and ovarian tumour. Coagulation disorders in cancer may be a mechanism for CRVO.
