Leiomyomas are the most common mesenchymal tumors of the vulva, which have an extremely low incidence. Although these tumors are known a low grade tumor, they have to be removed immediately to prevent further growing and sarcomatous change in the future. We experienced a case of leiomyoma of the vulva, and reported it with a brief review of literatures.

OBJECTIVE: To determine whether gene expressions of VEGF and PlGF are different between the human placenta of normal and abnormal pregnancy. METHODS: Placenta was collected at each trimester of normal pregnancy, missed abortion, intrauterine growth retardation and pre-eclampsia. Total RNA was extracted from placenta. Reverse transcription-polymerase chain reaction(RT-PCR) was performed using VEGF and PlGF primer. RESULTS: VEGF121, VEGF165 and VEGF189 were identified in normal pregnancy and missed abortion. In two cases of four IUGR and one case of three pre-eclampsia, four of isoforms (VEGF121, VEGF145, VEGF165, and VEGF189) were identified. The intensity of signal was strongest for VEGF165 in all cases. PlGF131 and PlGF152 were identified in all cases. However, the signal intensities of VEGF121, VEGF165, VEGF189, PlGF131 and PlGF152 were not different according to the gestational age. They were also not different between normal pregnancy and abnormal pregnancy. CONCLUSION: VEGF and PlGF were not only expressed at placenta but also overexpressed in part of IUGR and pre-eclampsia. The results suggest that VEGF may play a role in the induction of angiogenesis of placenta in normal pregnancy and its production may be increased under the hypoxic condition.

BACKGROUND: Although nucleotides -like Adenosine Triphosphate (ATP) and its derivatives Adenosine, were known to induce growth inhibition and apoptosis in diverse cell lines, little is known about their effects on trophoblast. OBJECTIVE: To elucidate the effects of extracellular ATP and adenosine on trophoblast cell growth and to delineate if apoptosis is involved in this mechanism. MATERIALS AND METHODS: We used TL cell line, derived from human term placenta. The cells were cultured for 24, 48, and 72 hours after being treated with ATP and adenosine, each. Also, cell growth according to different concentrations of ATP and adenosine was evaluated. To test whether apoptosis was induced by each nucleotide, DNA fragmentation and nuclear condensation by Hoechst 33258 stain and P53 protein expression were evaluated. RESULTS: Cell growth was inhibited by ATP and adenosine in time and dose-dependent manner. Furthermore, the growth inhibitory effect of adenosine was stronger than ATP, whereas signs of DNA fragmentation and nuclear condensation were observed in ATP treated cells, but not in adenosine treated ones. CONCLUSION: Our results shows that ATP and adenosine exert inhibitory effect on growth in TL cell line. These findings suggest that pathological production of ATP or its metabolites, adenosine, may lead to a pathologic status such as preeclampsia or intrauterine growth restriction.

Pyometra is an accumulation of purulent fluid in the uterine cavity. Generalized peritonitis secondary to a perforated pyometra is extremely rare. Most of the pyometra perforation is associated with malignancy. We have experienced a case of generalized peritonitis secondary to a perforated pyometra with no associated malignancy.

Conventional angiography still remains the procedure of choice in evaluation of cerebral aneurysm. However, MRI and MR angiography can play different roles in vizualizing cerebral aneurysm. A 43-year-old male was evaluated for recurrent seizure attacks. The brain MRI showed non-enhancing iso-signal mass on T1WI, signal voiding mass with stalk-like structure on coronal T2WI in the right temporal region. MRA also revealed dark round signal. However, the conventional cerebral angiography failed to visualize it. Finally, the mass was confirmed as a huge aneurysm filled with intraluminal thrombus on operation. It should seem that contrast media could not fill the aneurysmal sac because of intraluminal thrombus in conventional angiography. But aneurysmal sac seemed to be visible on MRA as paramagnetic artifact of thrombus. So, it can be assumed that MRA is superior to the conventional angiography in some cases of cerebral aneurysm, especially when it is associated with intraluminal thrombus.

Although the diagnosis of primary tuberculous peritonitis in pregnancy is seems challenging because of protean manifestations and difficult surgical intervention, prompt diagnosis and treatment can minimize both maternal and fetal/neonatal mortality. We have experienced one case of this disease in 23-year-old primigravida in 24 weeks of gestation.
