title: Chromaffin cells in the glomerular zone of adult rat adrenal cortex.
abstract: The occasional presence of islets of chromaffin cells in the glomerular zone of the adrenal cortex of adult rats, is reported in this light and electron microscope study. A possible error in organogenesis of the gland and the possible persistence of some foetal characteristics in these ectopic cells are discussed.
