[A case of multifocal acquired demyelinating sensory and motor neuropathy with whole body alopecia].

A 42 years-old male noticed alopecia in 2006. Three years later, he had loss of hair in the whole body and weakness in the left upper limb. Prednisolone treatment failed to alleviate these symptoms. In 2011, he was diagnosed multifocal acquired demyelinating sensory and motor neuropathy and treated by intravenous immunoglobulin (IVIg), which improved muscle strength eventually. Three years later, he had remitting weakness of the limbs, and thus underwent again IVIg with amelioration of both alopecia and weakness in the limbs. Association of multifocal acquired demyelinating sensory and motor neuropathy and alopecia, and their improvement by immunomodulatory treatment strongly suggest a role of immunological pathomechanism.
