Embolic tubular epithelial cells in percutaneous renal biopsies.
Four percutaneous renal biopsies with intravascular embolic tubular epithelial cells are presented. This unusual finding is presumably the result of the needle biopsy procedure and can be a puzzling and misleading artifact. It is postulated that dislodged tubular epithelial cells are pushed forward into or pulled back into punctured intrarenal arteries and subsequently transported to distant glomeruli.
