Hepatoblastoma (HB) is a rare embryonic malignant tumor of the liver. Most morphological studies on HB have limited to the histological characteristics and only 3 cases of HB have been described in the cytology literature. We present 2 cases of HB occurring in children aged 1 year and 3 years, respectively. The distinctive cytologic features of fine needle aspiration of HB were clusters of tumor cells showing acinar and trabecular pattern, smaller tumor cells with a high nuclear-cytopalsmic ratio and hyperchromatic nuclei having prominent nucleoli, and the presence of extramedullary hematopoiesis and osteoid material. These features were also found in the cell block and the biopsy specimen, and appeared very useful in the differentiation of HB from hepatocellular carcinoma.

Takayasu's disease is characterized by absent upper extremity pulses and ophthalmological finding of secreased visions and catract formation. Clinical features of Takayasu's disease are attributed to an obstructive arteritis of the large vessels criginating from aortic arch and other aortic segments. This dissease most frequently has been reported from Orient, and has affected primarily young females. This is a report of a 10 years old girl who developed the typical clinical and pathophysiological manifestation of Takayasu's disease and we also made brief review of literature.

PURPOSE: Endopyelotomy is a minimally invasive surgical alternative to the classic open surgery in the treatment of ureteropelvic junction obstruction with similar success rates. We analyzed factors influencing success rates after endopyelotomy based on clinical data. MATERIALS AND METHOD: Between 1989 and 1997, we performed percutaneous antegrade endopyelotomy in 53 cases of ureteropelvic junction obstructions. Among these patients, 47 patients have been followed with range from 3 to 70 months(mean 18.1 months). Of the 47 patients, 36 had primary UPJ obstruction and 11 had secondary UPJ obstruction. A rigid urethrotome(cold knife) was employed in 31 cases, a electrotome(hot knife) in 10 and a balloon dilator in 6. A stent(14/7Fr endopyelotomy stent or 6Fr double-J stent) was placed for 4 to 12 weeks after the procedure. Coexisting stones or infundibular strictures were managed simultaneously. RESULTS: Overall success rate(measured by symptom-free status and improved uroradiographic findings) was 80.9%(86.1% in primary and 63.6% in secondary cases). Success rates related to the method of incision were as follows; 87.1% with a cold knife, 80% with a electric knife and 50% with a balloon dilator only. 14/7Fr endopyelotomy stent was used in 21 patients with a successful outcome in 19(90.5%), while 25 received 6Fr double stent with a successful outcome in 18(72%). Success rates according to the duration of stenting were as follows; 86.7% in the 8-week group, 78.6% in the 6-week group and 66.7% in the 4-week group. CONCLUSIONS: Our experience indicates that endopyelotomy can be selected as the initial procedure of choice for the selected patients with UPJ obstruction. The small number of patients in each parameter did not reach statistical significance. However, there was a trend for better results in patients with primary UPJ obstruction and with the use of 14/7Fr endopyelotomy stent.
