AbstractA 9-month old female infant developed a non-healing deep necrotic ulcer on the tongue in apposition with the central incisors. There was no response to painful stimuli. Investigations revealed normal blood biochemistry, sweat, histamine and capsaicin tests. Nerve conduction studies and light microscopy of sural nerve and skin were normal. The child was diagnosed as a case of congenital indifference to pain and was treated with teeth extraction and plastic repair of the tongue. In next 2 years the child had recurrent ulcers of the tongue leading to fibrosis and shortening of tongue hampering the speech.
