Definition / General
  • Nests of adrenal tissue located away from adrenal gland
  • Also called heterotopia, although technically this term refers to displacement to an abnormal location, not the presence of accessory tissue elsewhere in body
  • Due to migration of adrenocortical primordial cells with gonads
Clinical Features
  • Usually without accompanying medullary tissue; cases near celiac ganglion may also contain medullary tissue
  • Common sites: retroperitoneal space along urogenital ridge, beyond renal capsule in upper pole, hilum of ovary or testes and along course of spermatic cord
  • Present in 1% of inguinal hernia sacs
  • May be accompanied by malformation of epididymis
  • May be fused with liver or kidney and surrounded by a common capsule
  • May undergo same disease processes as ordinary adrenal glandular
