Subacute multifocal painful neuropathy with spontaneous remission.

We present the cases of two patients with subacute onset of multifocal painful neuropathy with spontaneous remission and no relapse. The distribution of pain in patient 1 was hands (median > ulnar nerve region) and feet (peroneal and terminal tibial nerve regions), and in patient 2, hands (ulnar nerve region) and feet, left worse than in right. Both patients experienced facial numbness. Deep tendon reflexes were intact except for absent ankle jerks in patient 2. Motor nerve conduction studies demonstrated a marked prolongation of the distal motor latencies with normal proximal segment conduction velocities, suggesting distal demyelination. Cerebrospinal fluid protein concentration was elevated in patient 2, but no definite abnormality was found on sural nerve biopsy. A demyelinating neuropathy with a monophasic self-limited course may be consistent with Guillain-Barre syndrome (GBS). However, the multifocal painful sensory symptoms with facial numbness and the marked distal nerve conduction slowing in our cases are not consistent with GBS.
