[Amyotrophic lateral sclerosis syndrome of syphilitic origin. 5 cases].

We studied 5 cases of syphilitic lateral amyotrophic sclerosis. The diagnosis was based on the presence of a lymphocytic reaction in the CSF and positive VDRL and TPHA reactions in both blood and CSF. Clinically, the disease affected the arms in 3 cases and produced paraplegia in 2 cases.
