ABSTRACT
OBJECTIVE: To evaluate the accuracy of prenatal ultrasonographic diagnosis in fetuses with trisomy 13. MATERIAL METHOD: The present study consisted of all fetuses diagnosed of trisomy 13 and delivered at Ramathibodi Hospital between 1997 and 2006. RESULTS: There were 15 cases of trisomy 13. Twelve cases (80.0%) were detected by prenatal ultrasonographic examination, and 3 cases (20.0%) were missed. Mean maternal age was 31.4 years old. Sixty-six percent were diagnosed in 2" trimester (mean 19.4 weeks). The earliest gestational age for detection was 12 weeks 6 days. The most common abnormal ultrasonographic findings were holoprosencephaly (46.7%), and facial defects (40.0%). CONCLUSION: The accuracy of prenatal sonographic diagnosis in trisomy 13 fetuses was 80%. The most sensitive prenatal ultrasonographic findings in trisomy 13 were holoprosencephaly and facial defects.

Leiomyoma is common in the myometrial layer of the uterus, and rarely found in other genital organs. Previous reports show multiple sites of leiomyoma outside the uterus eg. vagina, oral mucosa or mandible vascular leiomyoma. Leiomyoma is normally a benign smooth muscle tumor and behaves as a hormone sensitive tumor Leiomyomas develop during the reproductive age and regress after menopause. The case of a 25 year old female with a large left labial leiomyoma presented as Bartholin's cyst. Illustrates the diagnostic difficulties in such cases. The management in this case was surgical excision. The definite diagnosis was confirmed by histologic examination as a labial leiomyoma.
