Sample text

Allergic contact dermatitis occurs as an allergic reaction to specific substances. As this involves a cell mediated response the inflammatory reaction occurs about two days after exposure and once the allergy is present further exposure will inevitably produce a reaction. Some substances are much more likely to produce an allergy, such as epoxy resin monomer, than others, such as cement, which characteristically requires exposure over many years before an allergy develops. In addition to the capacity of the substance to produce an allergic reaction, individuals also vary considerably in the capacity to develop allergies.

The differential diagnosis of blistering eruptions Widespread blisters • Eczema—lichenification and crusting, itching • Dermatitis herpetiformis—itching, extensor surface, persistent • Chickenpox—crops of blisters, self limiting, prodromal illness • Pityriasis lichenoides—pink papules, developing blisters • Erythema multiforme—erythematous and “target” lesions, mucous membranes affected • Pemphigoid—older patients, trunk, and flexures affected. Preceding erythematous lesions, deeply situated, tense blisters • Pemphigus—adults, widespread superficial blisters, mucous membranes affected (erosions) • Drug eruptions—history of drugs prescribed, overdose (barbiturates, tranquillisers) Localised blisters • Eczema—“pompholyx” blisters on hand and feet, itching • Allergic reactions, including topical medication, insect bites • Psoriasis—deep, sterile, non-itching blisters on palms and soles • Impetigo—usually localised, staphylococci and streptococci isolated • Herpes simplex—itching lesions developing turbid blisters Diseases presenting with blisters and pustules Itching Eczema pompholyx on hands and feet Allergic reactions Dermatitis herpetiformis Chickenpox Herpes simplex Non-itching Erythema multiforme Pemphigus vulgaris Bullous pemphigoid Bullous impetigo Insect bite allergy Pustular psoriasis on hands and feet Itching is a very useful symptom.

In the subacute variety there is less severe systemic involvement, with scattered lesions occurring on the face, scalp, chest, and arms. Treatment is with systemic steroids, with immunosuppressive agents if necessary. Antimalarial drugs, such as hydroxychloroquine, are more effective in the subacute type. In discoid lupus erythematosus there are well defined lesions with a combination of atrophy and hyperkeratosis of the hair follicles giving a “nutmeg grater” appearance. They occur predominantly on the cheeks, nose, and forehead.
