Dermatological emergencies.

Acute dermatological problems are seen regularly by physicians. This review aims to provide a framework for the diagnosis and management of urgent dermatological conditions. Cutaneous drug reactions are commonly seen and the different clinical presentations are discussed including the less common but important drug reactions Stevens-Johnson syndrome and toxic epidermal necrolysis. Erythrodermic patients also require prompt evaluation and management. Current guidelines for the management of urticaria and the common acquired autoimmune bullous disorders will be discussed. Patients with complications of eczema and psoriasis frequently require urgent in-patient management and patients with cellulitis and leg ulcers are also seen regularly on acute medical receiving units often requiring both medical and dermatological input.
