Ectopic adrenal cortex in neonatal liver

A small nodule of tissue, found deep within the liver parenchyma of a 3-day-old neonate, proved to be composed of adrenal cortical tissue of both fetal and adult types. Whilst ectopic adrenal tissue is widely recognized in many sites in the body, an intrahepatic localization does not previously appear to have been recorded. The possible mechanisms involved in the ectopia are discussed as is the potential relevance to neoplastic change.
