Bullous Sweet's Syndrome After Granulocyte Colony‐Stimulating Factor Therapy in a Child with Congenital Neutropenia

Abstract

We present the case of a 20-month-old boy with congenital neutropenia for which he was being treated with granulocyte colony-stimulating factor (G-CSF) who developed bullous Sweet's syndrome. Because of the challenging and extensive differential diagnosis of an acute bullous eruption in an immunocompromised child, we highlight the importance of a prompt and precise diagnosis before initiation of any systemic therapy in children with Sweet's syndrome.
