In the case presented here, the erythema and vesicles are widespread and show no linearity. Although irritant dermatitis may look like contact dermatitis it is not caused by an immunological mechanism. In patch testing strong allergic reactions are vesicular whereas irritant reactions show a non-vesicular erythema. The aetiological agent must be identified and removed. Cold wet compresses may be prescribed for the open areas where bullae and vesicles have broken open.
Compresses are valuable to relieve symptoms during the acute blistering stage.
They may be applied for 15 to 30 minutes several times a day. A strong topical corticosteroid may be used to treat the severe inflammatory reaction. Topical steroids are not effective in penetrating blisters but may be very valuable for the surrounding areas. Oral antihistamines may be given for itching. Aveeno baths may be used to soothe the area and control itching.
