Differential Diagnosis for Face Swelling
Single Most Likely Diagnosis
- Allergic Reaction: This is a common cause of face swelling, and the absence of new medications or lotions does not rule out an allergic reaction to food, insect bites, or other environmental allergens.
Other Likely Diagnoses
- Dental Infection: A dental infection, such as an abscess, can cause swelling of the face, particularly if the infection is located in the upper jaw.
- Sinusitis: Inflammation of the sinuses can cause swelling of the face, especially if the sinuses are infected.
- Trauma: A blow to the face can cause swelling, even if the patient does not remember the incident.
Do Not Miss Diagnoses
- Angioedema: A rare but life-threatening condition that can cause rapid swelling of the face, lips, and airways, potentially leading to respiratory obstruction.
- Cellulitis: A bacterial infection of the skin that can cause swelling, redness, and warmth of the affected area, and can be serious if left untreated.
- Lymphoma or Other Malignancy: Although rare, face swelling can be a symptom of lymphoma or other malignancies, such as a parotid gland tumor.
Rare Diagnoses
- Melkersson-Rosenthal Syndrome: A rare neurological disorder that can cause recurring episodes of facial swelling, particularly of the lips and face.
- Sarcoidosis: A rare autoimmune disorder that can cause inflammation and swelling in various parts of the body, including the face.
- Wegener's Granulomatosis: A rare autoimmune disorder that can cause inflammation and swelling of the blood vessels, including those in the face.
