The Initial Stage of Neutrophilic Dermatosis of the Dorsal Hands: A Case Report and Discussion of Differential Diagnoses.

Neutrophilic dermatosis of the dorsal hands (NDDH) is considered a localized variant of acute febrile neutrophilic dermatosis. It is a rare condition and presents with erythematous tender nodules and plaques on the extensor sides of the hands. Forty percent of NDDH cases occur in association with an underlying disease, with hematologic disorders being the most frequent type. Here, we describe the case of a 77-year-old male patient who presented with acute tumid, erythematous lesions of the fingers. As part of this report, we discuss possible differential diagnoses of NDDH and seek to raise awareness of this rare condition, as misdiagnoses often lead to a delay in adequate treatment and thus more dramatic disease courses.
