Abstract
Bullous Sweet's syndrome is a rare variant of the inflammatory neutrophilic dermatosis characterised by painful bullous skin lesions, fever, leukocytosis and a neutrophilic infiltrate of the dermis. The condition may be classified according to aetiology into classical (idiopathic), malignancy-associated and drug-induced. Neutrophilic infiltration occurs in response to a systemic insult. A punch biopsy for histology and culture is necessary due to its close resemblance to infection. Characteristic histology features a dense infiltration of neutrophils in the upper and mid dermis, oedema in the superficial dermis and endothelial swelling. Treatment with systemic glucocorticosteroids typically results in a dramatic clinical response. This case report illustrates a rare case of bullous Sweet syndrome associated with chronic lymphocytic leukaemia in a 53-year-old man.
