Norwegian scabies in the immunocompromised patient.

Norwegian, or crusted, scabies can be defined as a generalized severe scabies (Sarcoptes scabiei var. hominis) infestation usually affecting the immunocompromised patient that is most commonly seen with the leukemia-lymphoma group of neoplasms. The diagnosis is commonly missed, which can lead to mismanagement. We describe a patient with Norwegian scabies involving the lower extremities. The patient circumstances and treatment, as well as a review of the literature, are presented. The diagnosis of scabies should always be considered in patients with advanced malignancies and associated pruritus.
