Abstract

Epithelial ovarian neoplasms are uncommon in pediatric and adolescent patients, accounting for approximately 20% to 30% of ovarian tumors in adolescent females and women younger than 25. Tumors of low malignant potential (LMP) account for a significant proportion of epithelial neoplasms in this patient population. This case series describes 5 adolescent patients, with a mean age of 14.4 ± 2.4 years, diagnosed with ovarian tumors of LMP at one institution.

Between November 2001 and January 2006, 5 patients were diagnosed with ovarian tumors of LMP of 126 patients who had surgery for adnexal masses. All patients underwent initial surgery via laparotomy. Two patients underwent ovarian cystectomy, and 3 had at least a unilateral salpingo-oophorectomy. One patient had stage IIIc disease, whereas the other 4 patients, not all completely staged, had presumed stage I disease. Three patients developed recurrent ovarian masses on follow-up. Two had recurrent LMP tumors (one bilateral) and one was a benign mucinous cystadenoma.

This case series of 5 adolescent patients with ovarian tumors of LMP highlights the importance of considering epithelial neoplasms in any pediatric or adolescent patient with a pelvic mass and supports conservative management, with staging and fertility-sparing surgery; however, appropriate follow-up is essential, as evidenced by 3 of 5 patients exhibiting recurrent ovarian masses.
