Sweet's syndrome presenting as palmoplantar pustulosis.

Abstract

Sweet's syndrome was initially described as a reactive dermatosis characterized by sudden onset of fever, leucocytosis, and raised erythematous plaques infiltrated with neutrophils, and therefore called acute febrile neutrophilic dermatosis. However, later it became obvious that fever and neutrophilia are variable features, and a number of other characteristics have been described. Although the dorsa of the hands are frequently affected, the palmoplantar involvement mimicking pustulosis observed in our case appears to be unusual.
