Crusted scabies (otherwise known as Norwegian scabies) is an uncommon, highly contagious infestation that affects patients with a weakened immune system. The infestation presents with hyperkeratotic plaques with yellowish crusts located on the limbs, trunk, ears and eyebrows.
In crusted scabies, there are numerous mites within the stratum corneum. The stratum corneum is markedly thickened and there is epidermal acanthosis (figures 1, 2).
