Abstract

The disease characterized by the developmental and function disorders of T and B lymphocytes together with natural killer cells is called 'Severe combined immunodeficiency'. Due to the impairment of cellular and humoral immunity, opportunistic infections such as persistent diarrhea, recurrent pneumonia attacks, chronic sinusitis and oral candidiasis begin to be seen in the first 3 months, while cases left untreated lose their lives within the first 24 months. In this study, we present a 6-month-old male child with severe combined immunodeficiency presented with pneumonia, which is among the pediatric emergencies having a high morbidity and mortal results
