Ectopic anterior pituitary corticotropic tumour in a six-year-old boy

Histological, ultrastructural and immunocytochemical study
  • Kathryn Neilson
  • Jean-Pierre de Chadarévian


The report documents a silent, oncocytic, ACTH-producing ectopic anterior pituitary tumour in a 6-year-old boy. The invasive intrahemispheric neoplasm had no connection with the pituitary gland, the sella turcica or the sphenoid sinuses. The apparent similarities existing between this tumour, some choroid plexus carcinomas and steroid-producing neoplasms are discussed.
