title: Hereditary angioedema: an unusual cause of genital swelling presenting to a genitourinary medicine clinic.
abstract: We report a case of a new diagnosis of hereditary angioedema (HAE) presenting with genital swelling to a genitourinary (GU) medicine clinic. There is often a significant delay in diagnosing HAE, but it commonly presents with genital swelling before manifesting as potentially life-threatening visceral attacks. This case highlights the fact that HAE should be considered as an important differential diagnosis of genital oedema, as early recognition may help to prevent more serious future visceral episodes.
