Hyperkeratotic (Norwegian) scabies and onychomycosis in an immunosuppressed patient.

Hyperkeratotic scabies and onychomycosis were associated in an immunosuppressed patient. Onychomycosis healed spontaneously after treatment of scabies. A possible interrelationship between Sarcoptes scabiei infestation of the hyponychium and dermatophytes infestation of the nail plate could be responsible for this peculiar evolution.
