Facial edema is a relatively frequent clinical presentation encountered in patients seen in allergology and dermatology clinics. The differential diagnosis is broad, and sometimes the definitive diagnosis can be a challenge for the clinician. Facial angioedema itself encompasses different etiopathologies (histaminergic, bradykinergic, etc.) that must be distinguished from other causes of facial edema, such as allergic contact dermatitis, granulomatous conditions, inflammatory causes, infections, neoplasms or paraneoplastic syndromes, autoimmune diseases, among other entities hereby referred as miscellanea. A proper diagnostic approach is essential to order the appropriate tests, as well as to prescribe a targeted treatment. This review focuses on entities that present with facial edema and summarize their characteristic clinical features.
