Abstract: Introduction and Objectives: Ovarian tumours are rare in childhood, and account for 1-5% of all tumours. The aim of this study is to determine the epidemiological features, histological subtypes, and therapeutic management of ovarian solid ovarian tumours of the paediatric population of the province of Cordoba, in Spain.<br />Material and Methods: A retrospective, descriptive, observational and institutional study was conducted in which a review was made of the clinical histories of patients younger than 14years-old diagnosed with ovarian tumours, excluding secondary tumours in a University Hospital between 1994 and 2017. A review was carried out on the age, clinical presentation, laterality, diagnostic methodology, treatment, histopathology, and evolution of these tumours.<br />Results: A total of 37 ovarian tumours were reviewed in 31 patients, 6 of them being bilateral. The mean age was 10.3 (0-14) years, with 58% presenting as a palpable mass. There was no predominance of laterality. The tumour markers were negative. Conservative surgery was performed in 29.7% and adnexectomy in 70.3%. Only one case required post-operative adjuvant chemotherapy treatment (stageI immature teratoma with peritoneal gliomatosis). The histological study shows a predominance of germ cell tumours (65%) against those of epithelial lineage (22%). There were 3 stromal tumours that corresponded to fibroma (Gorlin syndrome), and bilateral gonadoblastoma associated with Frasier syndrome. The most frequent type of tumour was mature cystic teratoma (35.1%). There were no complications in the follow-up.<br />Conclusions: Given that most childhood ovarian tumours are benign, conservative surgery is considered as the first choice, being even more important in bilateral tumours. If there is a family history, it is essential to carry out molecular genetic studies, to rule out associated syndromes.<br /> (Copyright © 2020 Asociación Española de Pediatría.
