Scabies is an itchy immune hypersensitivity reaction to infestation of the skin by the mite Sarcoptes scabiei. Adult female mites burrow through the skin at the junction of the stratum corneum and the prickle cell layer, where they lay their eggs. Burrows then move out progressively towards the skin surface with the stratum corneum. Adult males and juvenile mites (larvae and nymphs) live mostly at the skin surface but may make temporary burrows for moulting from one development stage to another.
Infestation of immune-competent people is most common on the hands, digits and finger webs, and on the wrists. The flexor surfaces of the elbows, the axillae, ankles, buttocks, breasts and male genitalia may also be infested. In the elderly, infants and the immunocompromised the infestation may be more diffuse, including the head and neck, and palms and soles.
