[Eccrine hidradenitis. Case report and review of the literature]

Neutrophilic eccrine hidradenitis is a self-limited dermatosis with spontaneous resolution. The clinical presentation and location of the lesions are variable. Histopathologically, neutrophilic eccrine hidradenitis is characterized by a predominantly neutrophilic or mononuclear infiltrate around the eccrine ducts with associated necrosis. Possible causes include malignant hematological disorders, tumors, side effects of chemotherapy and bacteria infections. We report a 16-month-old female patient with idiopathic neutropenia undergoing G-CSF therapy, who suddenly developed numerous papules on her trunk and extremities. The lesions resolved spontaneously within 6 weeks without treatment. The clinical and histopathological findings of the hitherto published 45 cases are reviewed.
