Neutrophilic dermatosis of the dorsal hands

Neutrophilic dermatosis of the dorsal hands (NDDH) is a skin condition that presents with edematous pustular or ulcerative nodules or plaques localized to the dorsal hands.

Signs and symptoms
Neutrophilic dermatosis of the dorsal hands is characterized by bullae, pustules, and delicate erythematous plaques on the hands' dorsa.

Causes
Neutrophilic dermatosis of the dorsal hands is often associated with other conditions. Hematological disorders such as myelodysplastic syndrome and plasma cell dyscrasias are common.

Diagnosis
The histopathology of NDDH lesions shows a dense neutrophil infiltrate in the dermis, which is typically linked to leukocytoclastic debris and subepidermal edema.

Treatment
Systemic corticosteroids are the main method of treatment.
