<unk>  is a type of skin inflammation around the<unk> s due to damage by saliva from repetitive<unk>  licking and is classified as a subtype of irritant contact cheilitis. The resulting scaling, redness, chapping, and crusting makes a well-defined ring around the<unk> s. The rash may extend as far as the tongue can reach and usually does not occur at the corners of the mouth. It commonly occurs during winter months but some people can have it year-round if<unk>  licking is a chronic habit.<unk>  differs from perioral dermatitis, which spares the vermilion border. Allergic contact dermatitis presents similar signs and symptoms that can be differentiated from<unk>  with an allergy patch skin test. It is treated with simple moisturizers, emollients, and sometimes topical steroids, while perioral dermatitis is worsened by topical steroids. It is important to identify the cause of the inflammation, whether it is due to<unk>  licking or a more complex cause, in order to successfully treat and alleviate symptoms. Children are affected more often than adults and sometimes special approaches need to be considered especially if there is a psychological aspect to the<unk>  licking behavior.
