To improve clinical appreciation of these lesions, we reviewed the presentation, evaluation, outcome, and therapeutic aspects of painful adnexal masses in adolescent females. During the period January 2005-September 2006, 63 adolescent females with painful adnexal masses were recruited. The patient management and outcomes were documented. The mean age was 15.36±1.6 years, and the mean diameter of the masses was 54.5±1.3 mm. Forty-nine patients (77.7%) underwent surgical management, and 45 of the 49 surgeries were achieved by laparoscopic surgery (91.8%). Two converting laparotomies (4%) were performed. Fourteen patients with a presumed functional cyst were followed up without surgery. Postoperative histopathologic evaluation revealed a benign epithelial ovarian cyst rate of 26.5%, a mature cystic teratoma rate of 22.4%, and a borderline ovarian tumor rate of 4.08%. Non-neoplastic adnexal lesions were encountered in surgeries of 22 cases. The incidence of acute ovarian torsion and true ovarian neoplasm was 9.52% and 55.1%, respectively, and none was malignant. True ovarian neoplasia remains a common indication for surgery in the majority of adolescents. Because most cases are benign, minimal access surgery should be performed whenever feasible.
