A case of neutrophilic dermatosis of the dorsal hands with concomitant involvement of the lips.

Neutrophilic dermatosis of the dorsal hands (NDDH) is a localized, pustular variant of acute febrile neutrophilic dermatosis (Sweet syndrome). The lesions of NDDH clinically resemble those of Sweet syndrome (SS), but they differ from classic SS according to their locations (NDDH is predominantly restricted to the dorsal hands) and the smaller number of accompanying systemic symptoms. The histology of the NDDH lesion shows a dense dermal neutrophilic infiltration. The lesions rapidly resolve after systemic corticosteroid and/or dapsone therapy. We herein report on a case of neutrophilic dermatosis of the dorsal hands in a 34-year-old woman. The patient also had skin changes with erythematous plaque on the right lips.
