We report a patient with concurrent chronic inflammatory demyelinating
polyradiculoneuropathy (CIDP) and alopecia universalis. A dramatic im
provement in strength accompanied the administration of prednisone, al
though no regrowth of hair was noted. CIDP and alopecia universalis ar
e two relatively rare autoimmune disorders. The simultaneous occurrenc
e of these disorders suggests a common pathogenetic mechanism, includi
ng the possibility of shared antigens between peripheral nerve myelin
and the hair follicle. (C) 1998 John Wiley & Sons, Inc.
