Ovarian epithelial tumors (cystoadenomas/cystoadenocar-cinomas) are not as common in girls as the germinal tumors (teratomas). Mucinous or serous borderline cystoadenomas (CAdB) with a low malignant potencial, represent 20% of epithelial tumors. As an intermediate type of bening-malignant neoplasia, these tumors are usually giant cystic pelvic masses found in young females, but exceedingly rare before menarche. Stage 1 (tumor limited to the ovary) is the most frequent stage at diagnosis. Bilateral ovarian compromise occurs in 10-15% of patients. Open surgery is preferrred to perform a fertility sparing procedure such as oophorectomy, salpingo-oophorectomy or even a tumorectomy in selected cases. The latter requires intraoperative biopsy confrmation of free margins, to prevent recurrence. Prolonged follow up is indicated to detect a recurrence or a contralateral tumor development. Survival is excellent in most of these patients. We present the case of a premenarchal girl with a huge mucinous CAdB.
