Which sites are commonly involved in orolingual angioedema?

• A. Lips, tongue, mouth, throat
• B. Ankles and feet
• C. Ears
• D. Scalp

Answer: (A)

Oralingual angioedema mainly affects the structures of the mouth and throat because these mucosal tissues are highly vascular and can rapidly swell when permeability increases. The lips, tongue, floor of the mouth, soft palate, and other parts of the oral/pharyngeal area are the classic sites because swelling here directly narrows the airway and can become life-threatening if not recognized and managed promptly. Edema in other regions like the ankles and feet, ears, or scalp isn’t typical for this condition, since those areas aren’t the primary sites involved in orolingual angioedema. Recognizing the pattern of swelling in the lips and tongue helps identify the risk to the airway and guides urgent assessment and appropriate management.
