Mucinous cystadenomas are rarely seen. Further, the recurrence of mucinous cystadenomas is very rare. This report describes a case of ovarian mucous cystadenoma in an adolescent that recurred 1 year after surgery. Case presentation A 13-year-old patient, with a sizable ovarian tumor underwent laparoscopic-assisted cystectomy. On histopathology, the tumor was diagnosed to be an ovarian mucinous cystadenoma. The mucinous cystadenoma recurred 13 months after surgery and subsequently laparoscopic right adnexectomy was performed. Clinical discussion It has been reported that intraoperative cyst rupture and cystectomy instead of adnexectomy are risk factors for mucinous cystadenoma recurrence. Close follow-up is required for post-cystectomy patients because of the possibility of recurrence. Conclusion The risk of recurrence and the preservation of fertility should be carefully considered when deciding on treatment in young patients with a mucinous cystadenoma.}, title = {A case of ovarian mucinous cystadenoma in a child that recurred 1 year after surgery}, volume = {83}, year = {2021} }
