    Abstract:
    Severe congenital neutropenia (SCN) is a rare primary myelopoiesis disorder, characterized by persistent severe neutropenia and early-onset bacterial infections. Herein, we describe an 11-month-old male who was referred with recurrent cutaneous infections and chronic diarrhea. Serial complete blood counts indicated persistent neutropenia. Bone marrow aspiration of the patient demonstrated maturation arrest of myeloid series at promyelocyte-myelocyte stages. W44X mutation in the HAX1 gene confirmed the diagnosis of SCN. The patient was successfully treated with granulocyte colony-stimulating factor. Severe congenital neutropenia should be considered in children with early-onset recurrent infections and neutropenia, since early diagnosis and appropriate treatment can prevent further complications.
