RESUMEN
Introduction : The functional ovarian cyst remains a rare disease in the prepubertal population; it is however a leading cause of precocious pseudo-puberty. Precocious puberty results in significant changes marked by growth acceleration and premature closure of growth plates. We report in this article the case of a precocious pseudopuberty secondary to a functional ovarian cyst
Case presentation: A six and a half years old patient, consulted for a recent appearance of early breast development. Hormonal analysis revealed a distal hormonal secretion with suppression of the hypothalamic-pituitary axis. Pelvic ultrasound revealed the presence of a large right ovarian cyst, confirmed by pelvic MRI. The management of this patient consisted in a simple monitoring. After two months, a complete regression of the symptoms was noted as well as a complete disappearance of the ovarian cyst on ultrasound, and an elimination of the hypothalamic-pituitary axis suppression on hormonal analysis
Conclusion: Ovarian cysts are mostly self-limited and require no treatment with spontaneous regression. In rare cases surgery is necessary; it is important to consider a conservative intervention of ovarian tissue without affecting fertility. Ovarian cysts are rare in the pediatric population and with good prognosis in their majority; they require however the attention of the pediatrician, given the possible risk of malignancy
