Norwegian scabies in Australian Aborigines.

Norwegian scabies is a rare, but distinctive, variant of scabies. The infestation by the parasite is massive, and the lesions consist of hyperkeratotic plaques affecting the skin of the whole body. Predisposition to this form of scabies occurs in association with a variety of conditions. Three cases of Norwegian scabies, which occurred in full-blood Australian Aborigines, and were managed in the Royal Darwin Hospital, are reported.
