Acute Genital Swelling Heralding C1 Esterase Inhibitor Deficiency in a Child

Abstract

A healthy 5-year-old boy presented to the emergency department with an acute genital swelling. He had no relevant family history. His presentation and blood investigations were consistent with C1 esterase inhibitor deficiency, mostly likely arising de novo. A rare cause of acute genital swelling and its management are discussed.
