Angular cheilitis (AC) is inflammation of one or both corners of the mouth.[4][5] Often the corners are red with skin breakdown and crusting.[2] It can also be itchy or painful.[2] The condition can last for days to years.[2] Angular cheilitis is a type of cheilitis (inflammation of the lips).[6]
Angular cheilitis can be caused by infection, irritation, or allergies.[2] Infections include by fungi such as Candida albicans and bacteria such as Staph. aureus.[2] Irritants include poorly fitting dentures, licking the lips or drooling, mouth breathing resulting in a dry mouth, sun exposure, overclosure of the mouth, smoking, and minor trauma.[2] Allergies may include substances like toothpaste, makeup, and food.[2] Often a number of factors are involved.[2] Other factors may include poor nutrition or poor immune function.[2][5] Diagnosis may be helped by testing for infections and patch testing for allergies.[2]
Treatment for angular cheilitis is typically based on the underlying causes along with the use of a barrier cream.[2] Frequently an antifungal and antibacterial cream is also tried.[2] Angular cheilitis is a fairly common problem,[2] with estimates that it affects 0.7% of the population.[3] It occurs most often in people in their 30s to 60s, and is also relatively common in children.[2] In the developing world, iron, vitamin B12, and other vitamin deficiencies are a common cause.[5]
