Bullous cellulitis-like sweet syndrome in a patient with Waldenstrom macroglobulinemia

Abstract

Neutrophilic dermatoses comprise a wide spectrum of inflammatory diseases with overlapping features characterized histologically by the presence of an aseptic neutrophilic infiltrate in the epidermis, dermis, and/or hypodermis and are often associated with systemic inflammatory and neoplastic disorders. Here we report a case of a 75-year-old man who developed painful indurated plaques with a vesicular, bullous, and even hemorrhagic appearance similar to cellulitis on his right leg along with a fever that raised his body temperature up to 39°C and malaise.
