Definition / General
  • Allergic contact dermatitis: click here
  • Atopic dermatitis: pruritic disease of unknown origin; usually begins in infants; eczematous lesions, lichenification (thickening with increase in skin markings), dry skin; may be familial (hay fever, asthma, and eczema); occurs on flexural surfaces
  • Drug-related: usually systemic (penicillin); eosinophils present in deep dermis
  • Eczema: red, papulovesicular, oozing and crusted lesions (spongiotic dermatitis) which evolve to raised, scaling plaques (epidermal hyperplasia and excessive scale)
  • Irritant contact dermatitis: click here
  • Photo-dermatitis: due to UV light exposure
  • Primary irritant dermatitis: due to repeated rubbing
Treatment
  • Potential allergens should be identified and avoided
  • Topical steroid ointments and tars are the mainstays of therapy
  • Clobetasol combined with zinc sulfate cream may be more effective than clobetasol alone (J Eur Acad Dermatol Venereol 2008;22:531)
