A Case of Severe Erythroderma in a Patient with Pustular Psoriasis.

CASE PRESENTATION

A female patient with a known history of pustular psoriasis presented with sub-acute development of diffuse erythema and scaling of the skin with areas of exfoliation consistent with erythroderma. She was ill appearing and required admission and aggressive treatment with steroid-impregnated wet dressings, topical emollients, analgesics, and systemic immunosuppressants.

DISCUSSION

Erythroderma is a dermatologic emergency characterized by diffuse erythema and scaling spanning greater than 90% of skin surfaces and is associated with a mortality rate as high as 64%. It is initially a clinical diagnosis and needs to be recognized and aggressively treated expeditiously to improve chances of a good outcome.
