Radiology–pathology conference: neutrophilic fasciitis and panniculitis of the feet (Sweet's syndrome)

Sweet's syndrome is characterised by pyrexia, cutaneous lesions, neutrophilia and an infiltrate of mature neutrophils in the dermis. While extracutaneous disease is not uncommon, neutrophilic fasciitis has rarely been described. We report the imaging appearances with clinical and histological correlation of a case of drug-induced neutrophilic fasciitis in a 56-year-old man.
