We experienced one patient with insensitivity to pain which caused pathologic fractures and deformity of the extremities. The patient, nine years old girl, has clinical manifestations of insensitivity to pain, which are described in the literatures, as corneal opacity, no response to painfull stimula, scarred tongue, deformity of joint etc.
From her clinical history pathologic fractures have easily occurred with no subjective complaint.
In this case congenital leucopathia is also observed. It is difficult to prove insensitivity to pain.
