title: Neutrophilic dermatoses in two children with idiopathic neutropenia: association with granulocyte colony-stimulating factor (G-CSF) therapy.
abstract: Painful neutrophilic skin lesions were observed in two children receiving granulocyte colony-stimulating factor (G-CSF) for treatment of idiopathic neutropenia. A girl with cystic fibrosis and cyclic neutropenia developed an erythematous papular eruption without fever or neutrophilia 7 months after commencing therapy with G-CSF. A skin biopsy specimen revealed microscopic, sterile, neutrophilic abscesses. A boy with chronic neutropenia and recurrent inflammatory skin lesions developed multiple erythematous nodules following administration of G-CSF. A biopsy specimen showed neutrophilic panniculitis. We believe that these skin eruptions belong to a spectrum of neutrophilic dermatoses that can be induced or aggravated by G-CSF therapy.
