Abstract
OBJECTIVES
The aim of this study is to determine the laterality of incidence of ovarian cystic teratoma.
METHODS
We retrospectively reviewed medical records, laboratory data, and radiologic results of 56 patients who underwent ovarian cystectomy and/or oophorectomy for ovarian mass and were diagnosed as mature cystic teratoma from March 2010 to September 2011.
RESULTS
A total of 56 cases of mature cystic teratoma were included. Thirty one cases (55.4%) of mature cystic teratomas were located on the right ovary, 15 cases (26.8%) were found on the left ovary, and the remaining 10 cases (17.9%) were found on both ovaries. Right-sided ovarian cystic teratomas were more frequently affected in cases of ovarian torsion than left-sided ones (9.8% vs 0.0%; P=0.046). Among 10 patients with bilateral ovarian teratomas, the mean two dimensional size of right-sided ovarian teratomas (44.29+/-16.00 cm2) was bigger than that of left-sided ones (16.87+/-5.65 cm2).
CONCLUSION
Incidence of unilateral ovarian cystic teratomas may occur more often on the right side.
