title: Renal angiomyolipoma: ultrastructural study.
abstract: An angiomyolipoma from a twenty-six-year-old woman was studied by electron microscopy. The tumor was composed of a mixture of mature smooth muscle cells, fat cells, and abnormal blood vessels. MAny of the smooth muscle cells showed excessive intracytoplasmic accumulation of glycogen, while the abnormal blood vessels lacked a normal media.
