We report a case of spontaneous hemorrhage secondary to renal angiomyolipoma treated with percutaneous transcatheter arterial embolization. Fourteen and 18 months after the procedure, the patient showed repeated spontaneous hemorrhage during pregnancy. However, a healthy female infant was delivered at the 39th week of the pregnancy. We discuss the management of renal angiomyolipoma in young married women before pregnancy.

The expression of telomerase activity in pheochromocytoma clearly suggests the malignant behavior of the component cells. Analysis of telomerase activity appears to be a powerful tool for the diagnosis of malignant pheochromocytoma.

In the presence of palladium(II) chloride, 2-bromoanilines readily react with the methyl vinyl ketone and the ethyl acrylate to produce vinylogous arylamino ketones and esters. A palladium(0)-assisted cyclization of the arylamino ketones and the esters leads to a formation of 3-substituted indoles.

The electropermeabilization technique has the potential to serve as a new and effective modality for the treatment of bladder cancer.

Reliable prediction of malignant behavior on the basis of histopathology also is notoriously difficult.1,2 We previously attempted to determine whether there are any conspicuous abnormalities in the the levels of catecholamine metabolites in malignant pheochromocytoma 3 and whether analysis of nuclear DNA ploidy can contribute to characterization of the biologic behavior of the tumor. 4 The concentrations of aneuploid DNA content is a frequent occurrence in clinically benign pheochromocytomas and that aneuploidy per se should not be con-
