Abstract
Hereditary angioedema is a rare disease with great heterogeneity in symptoms. Although there are three types, the most common is type I, which is the result of a deficiency of the complement inhibitor C1 (C1-INH). Symptom severity, along with the need to start an appropriate specific management, make the diagnosis challenging for the physician. We report the case of an 8-year-old male patient who presented to the emergency department with dyspnea, dysphagia and cervical edema. During the evaluation, no obstruction of the airway was evident. Due to family history, hereditary angioedema was suspected and complement (C4) and C1-INH levels, and C1-INH function were measured, with results confirming the diagnosis. It is vital for healthcare professionals to recognize this pathology in order to direct treatment to both resolve the acute episode of angioedema as well as to prevent future episodes from happening.
