title: Acral manifestations of Sweet syndrome (neutrophilic dermatosis of the hands).
abstract: Neutrophilic dermatosis of the hand (NDH) is a rare localized variant of the syndrome, originally described two decades ago by Strutton et al. The lesions of NDH and Sweet syndrome are similar, as indicated in the first report of NDH. Both diagnoses are characterized by an acute onset of fever, leukocytosis, and tender, erythematous infiltrated plaques. There are also bullae and ulceration in NDH, in contrast to Sweet syndrome, in which bullae are quite uncommon, especially at the early stages. Similar to Sweet syndrome, the majority of NDH patients are women (69%). Patients with NDH present with fever, peripheral neutrophilia, leukocytosis, and/or an elevated erythrocyte sedimentation rate or C-reactive protein level, but at a significantly lower rate than those in Sweet syndrome (33%). Similar to Sweet syndrome, NDH has been associated with the following conditions: Malignancies (particularly hematological [21%], most common of which is acute myelogenous leukemia, but many other malignancies as well), inflammatory bowel disease (19%), medication and vaccination-related eruptions, bacterial and viral infections, rheumatologic diseases, and others. The clues to the diagnosis of NDH are the same as for Sweet syndrome. Awareness of this diagnosis is important not only to avoid unnecessary medical and surgical therapy and to expediently initiate the administration of steroids for this highly responsive dermatosis, but also to conduct an appropriate workup to exclude associated diseases, especially malignancies.
