Life-threatening pustular and erythrodermic psoriasis responding to infliximab. 
Pustular and erythrodermic psoriasis can be a debilitating and recalcitrant disease which may result in secondary complications such as sepsis, electrolyte imbalance, renal failure, and heart failure.  We report a case of a 46-year-old patient with life-threatening erythrodermic psoriasis who responded rapidly to intravenous infliximab.
