[Familial carpal tunnel syndrome].

As the incidence of the carpal tunnel syndrome among family members of patients is not precisely defined in the literature, we described here two new cases. Few authors reporting on patients with the carpal tunnel syndrome refer to the familial occurrence of the disorder. Median nerves were constricted under thickened carpal ligaments. In one case, we looked for amyloidosis in the transverse carpal ligament under electron microscope but we could not find any.
