  • Grossly:
    • Erythematous papular rash -> scales, crusts, alopecia -> lichenification when chronic
    • Start on neck and ears -> head, face, paws -> generalised
  • Microscopically:
    • Epidermal hyperplasia, spongiosis, crusts
    • Superficial perivascular dermatitis

Pathogenesis

Infection begins on the ear tips and spreads over the body a notoedric skin infestation

  • Causes dermatitis
  • Burrowing of females damages keratinocytes leading to cytokine release
  • Hypersensitivity reaction may occur
    • Eosinophils
