Occasionally, the patient may feel unwell with fever and loss of appetite. Non-eczematous id reactions include erythema nodosum , Sweet syndrome , guttate psoriasis and blistering diseases. How is disseminated secondary eczema diagnosed?
The clinical features of disseminated secondary eczema are characteristic. Finding the cause depends on taking a careful history of the initial site of a skin problem. Sometimes the patient does not associate a chronic minor rash with their current widespread and symptomatic eruption. What is the treatment for disseminated secondary eczema?
The primary rash needs to be treated vigorously. This may require systemic therapy, eg antibiotics for bacterid or oral antifungal for confirmed dermatophytid. The secondary eczema is often extensive and highly symptomatic. Treatment may entail: Referral for specialist assessment and treatment, including admission to hospital Wet wraps or dressings for weeping eczematous plaques Potassium permanganate , soaks for localised oozing, infected areas Potent topical corticosteroid creams for weeks Systemic corticosteroids , eg prednisone or prednisolone for several weeks Oral sedating antihistamines at night.
Favorite Table Print Autosensitization Dermatitis at a Glance An acute disorder triggered by infection, stasis and contact dermatitides, ionizing radiation, blunt trauma, and retained suture material. Widespread, pruritic, usually papulovesicular eruption, most frequently affecting the extremities. Related features are those of the precipitating disorder. Pathology is nondiagnostic and most often consistent with an acute spongiotic process of the epidermis with a superficial, perivascular, lymphohistiocytic infiltrate of the dermis containing occasional eosinophils. Other precipitating factors for autosensitization have included the application of irritant or sensitizing chemicals, 14 ionizing radiation, 15 , 16 and retained suture material. In these studies, such autoreactive T-cell clones could not be derived after treatment with irritants. Nonetheless, the authors speculated that T cells autoreactive to keratinocyte antigens may be generated during the course of contact hypersensitivity and lead to the development of an id reaction.
