Paediatric ovarian neoplasms are rare and histologically diverse tumours with distinct clinical behaviour and prognosis compared to their adult counterparts. This review synthesises current knowledge from an anatomical pathology perspective, emphasising diagnostic and therapeutic strategies. Paediatric ovarian tumours are classified into three main categories: germ cell tumours, sex cord-stromal tumours, and epithelial neoplasms. Germ cell tumours, the most frequent in children, include dysgerminoma, mature and immature teratoma, yolk sac tumour, and choriocarcinoma. Sex cord-stromal tumours encompass Sertoli-Leydig cell tumours, juvenile granulosa cell tumours, and adrenal-like stromal tumours, while epithelial tumours, rare in paediatric patients, include serous and mucinous adenocarcinomas or cystadenomas. Clinical presentation is often nonspecific, with abdominal pain, pelvic mass, or endocrine abnormalities. Diagnosis integrates imaging, serum tumour markers, and histopathology supported by immunohistochemistry. Treatment prioritises fertility-sparing surgery, with selective adjuvant chemotherapy based on histotype and stage. Despite generally favourable outcomes, the rarity of these tumours limits high-quality evidence, highlighting the need for referral centres and multicenter studies. Standardised diagnostic protocols and personalised therapeutic approaches are essential to optimising clinical outcomes and preserve long-term reproductive function.
