How is angular cheilitis diagnosed?

Your primary healthcare provider or a dermatologist (provider specializing in skin conditions) can diagnose angular cheilitis. They will:

• Check your symptoms.
• Perform a physical exam.
• Review your medical history.

They may do a mouth swab to test for viruses like herpes or fungal infections. Blood tests check for illnesses or nutritional deficiencies.
