Sweet's syndrome associated with cellulitis.

A 38-year-old woman developed an acute, painful cutaneous eruption on her lower legs, neck, chest and fingers while receiving a number of oral and intravenous antibiotics for left leg cellulitis caused by trauma. Clinically and histopathologically, she was diagnosed with Sweet's syndrome with typical pseudovesicular skin changes in conjunction with erythema nodosum-like lesions on her lower legs. She responded quickly to oral prednisolone. We propose Staphylococcal cellulitis as a cause of Sweet's syndrome.
