A Case of Vulvar Leiomyoma / 대한산부인과학회잡지

Vulvar leiomyoma is a rare benign solid tumor of the vulva. Their incidence is not known as most reports are of a single case or small series, and their origin is not known exactly. Most cases are asymptomatic and local excision is recommended as initial therapy and also for recurrences. We have experienced vulvar leiomyoma (the labia majora and vestibule of the vagina) in a 51 years old woman and present it with a brief review of the literatures.

Prenatal Diagnosis of Choledochal Cyst at 23 weeks by Sonography / 대한산부인과학회잡지

In the past few years a wide variety of fetal abnormalities have been successfully prenatal diagnosed by maternal sonography. Early excision of the choledochal cyst in the newborn is considered to be the optimal treatment and may pose less risk to the patient than delayed surgical exploration. We present a new case diagnosed a choledochal cyst at 23 weeks gestation by routine ultrasound scanning. At 38 weeks gestation a female infant was born by spontaneous delivery. At 7 weeks of age the patient underwent a laparotomy performed cyst excision with Roux-en-Y hepaticojejunostomy. We experienced a case of choledochal cyst at prenatal sonography and report our case with a brief review of literature.

Transabdominal sonography of the cavum septum pellucidum in normal fetuses in the second and third trimesters of pregnancy / 대한산부인과학회잡지

OBJECTIVE: To assess the visualization rate and size of the cavum septum pellucidum (CSP) by transabdominal sonography in normal fetuses in the second and third trimesters of pregnancy. METHODS: The CSP was prospectively researched and measured using an axial transventricular plane in 308 consecutive uncomplicated singleton pregnancies between 15 and 41 weeks of gestation. RESULTS: The CSP was seen in 42.5% of cases at 15 weeks, 84.78% at 16-17 weeks, 100% at 18-37 weeks and 81.25% at 38-41 weeks. Compared to biparietal diameter (BPD), the visualization rate was 35.29% between 31 and 32 mm, 47.8% between 33 and 34 mm, 84% between 35 and 43 mm, 100% between 44 and 88 mm and 87.5% between 89 and 101 mm. Mean CSP width was 5.5+/-1.7 mm (range 2-9 mm). The CSP width was increased with gestational age and BPD, but with a slight decrease around term. CONCLUSION: In normal fetuses the CSP should always be visualized between 18 and 37 weeks, or with a BPD of 44-88 mm. Failure to observe the CSP in this interval, or possibly the presence of a large CSP, may indicate abnormal cerebral development and warrant further investigation. Conversely, absence of the CSP prior to 18 weeks, or later than 37 weeks, is a normal finding.

Angiomyofibroblastoma of the Vulva: A case report

Angiomyofibroblastoma is a distinctive, hitherto uncharacterized, benign soft tissue tumor of the vulva with histology similar to an aggressive pelvic angiomyxoma. It can be distinguished from an aggressive angiomyxoma by its circumscribed borders, higher cellularity, more numerous blood vessels, the frequent presence of plump stromal cells, minimal stromal mucin, and rarity of erythrocyte extravasation. We experienced a case of angiomyofibroblastoma of the vulva occurring in a 45-year-old woman. The lesion was a well-defined but not encapsulated mass, 4.5x4.2 cm. Histologically the mass was characterized by alternating hypercellular and hypocellular edematous zones in which abundant blood vessels were irregularly distributed. Immunohistochemically, the spindled, plump spindled, and oval stromal cells were reactive for vimentin and desmin, but not for cytokeratin, or S-100 protein.
