Abstract

Objective: The objective of the study was to evaluate the clinical characteristics of ovarian teratoma by age.

Study design: This was a retrospective study. Five hundred eighty medical records were reviewed from patients who underwent operative removal of ovarian teratomas at Samsung Medical Center between January 1996 and February 2010.

Results: The proportion of asymptomatic patients increased significantly after 20 years of age (P = .0006). Ovarian torsion was noted in 26 patients (4.9%), without an age-specific difference (P = .5019; range, 0.0-8.2%). Tumor size was different according to age group (P < .0001), with larger tumor size in younger patients (<20 years old) relative to older patients. Immature teratoma revealed a higher incidence of symptomatic tumors on the first visit and significantly larger tumor size (P = .0004) compared with mature teratoma.

Conclusion: Patients with ovarian teratoma have different clinical manifestations by age. It could help us understand clinical characteristics of the disease.
