In order to evaluate the clinical and pathologic presentation of mature cystic teratomas and trends in management, 291 cases were analyzed with respect to patient age, annual incidence, symptoms, methods of diagnosis, tumor size, bilaterality and
methods of management.
@ES The obtained results were as follows.
@EN 1. The mean age was found to be 31.8±10.6 years old and there were an average of 24.3+12.2 cases per year.
2. The symptoms were abdominal pain, pelvic heaviness, palpable abdominal mass, abnormal uterine bleeding, backache, dysmenorrhea and the 89 cases(30.6%) were asymptomatic.
3. Diagnosis was made by pelvic examination, ultrasonogram, CT and MRI.
4. The mean tumor size was 8.4±3.8cm and bilaterality rate was 16.5%. The mean cyst diameter for patients undergoing cystectomy was 7.6±2.8cm; for oophorectomy, 8.4±3.8cm; and for hysterectomy, 8.9±4.2%.
5. The most common complications of tumor were torsion(7.0%) and rupture(4.0%), and these complications were not correlated with tumor size.
6. mature cystic teratomas were found in association with uterine myoma(5.2%) and functional cyst(4.8%) on the contralateral oavry.
7. When compared to cystectomies, oophorectomies were performed more fequently for tumors of larger than 6cm in diameter(p=0.01).
8. The number of hysterectomies increased with an increasing age. The number of oophorectomies decreased markedly but the number of cystectomies increased since the year of 1989 in the group of mature cystic teratoma under 35 years of age, of
which
size is between. 4.0 and 8.0cm.
