title: [Congenital analgesia].
abstract: The case of a 12 years old boy with a congenital anaesthesia covering all cutaneous and visceral districts is reported. There were no other neurological abnormalities apart a light mental retardation and loss of axon reflex after intradermal injection of hystamine. Notwithstanding this last finding a diagnosis of congenital indifference to pain was made. The differential diagnosis between indifference and insensitivity to pain is discussed.
