Résumé
Nezelof's syndrome(combined immunodeficiency with immunoglobulin) is a hereditary primary immunodeficiency characterized by recurrent chronic pulmonary infections, oral and cutaneous candidiasis, failure to thrive, chronic diarrhea, skin infection, urinary tract infection, gram-negative sepsis, severe progressive varicella infection, lymphopenia, diminished lymphoid tissue, abnormal structure of the thymus, and presence of normal or increased levels of one or more of the major immunoglobulin classes, but with impaired antibody synthesis. We experienced a case of Nezelof's syndrome in 5-month-old boy who complained cough, poor feeding, vomiting and diarrhea in first admission day and discharged with recovered general condition in 38th admission day and then died of recurrent bacterial and fungal infections and malnutrition in 15-month-old age. He had no thymic shadow in chest X-ray and immunologic abnormalities including decreased lymphocyte count, decreased T cell count and function, normal number of B cell count and immunoglobulins with funtional impairment in antibody synthesis. We report a case of Nezelof's syndrome with brief review of related literatures.
