We report a previously healthy 16-month-old child who presented to us with membranous pharyngitis and ecthyma gangrenosum. In this patient, Pseudomonas aeruginosa was isolated from throat swab, cerebrospinal fluid, skin swab, urine, blood and synovial fluid in a single admission. In further workup, this child was diagnosed as a case of X-linked agammaglobulinaemia. The child was treated successfully with antipseudomonal antibiotics for 6 weeks and intravenous immunoglobulin.
