cheilitis

 [ki-li´tis]
inflammation of the lips.
actinic cheilitis (cheilitis acti´nica) involvement of the lips after exposure to actinic rays, with pain and swelling and development of a scaly crust on the vermilion border; it may be acute or chronic. Called also solar cheilitis. (See Atlas 3, Part E.)
angular cheilitis single or multiple fissures and cracks at the corner of the mouth on one side or both sides, which in advanced stages may spread to the lips and cheeks. Causes include primary or superimposed infection with microorganisms such as Candida albicans, staphylococci, or streptococci; poor hygiene; drooling of saliva; overclosure of the jaws in patients without teeth or with ill-fitting dentures; riboflavin deficiency; or other causes. Called also perlèche.
solar cheilitis actinic cheilitis.

an·gu·lar chei·li·tis

inflammation and fissuring radiating from the commissures of the mouth secondary to predisposing factors such as lost vertical dimension in denture wearers, nutritional deficiencies, atopic dermatitis, or Candida albicans infection.

angular cheilitis, angular cheilosis

See perlèche.

angular cheilitis

A condition characterised by inflammation, exudation, maceration and fissuring at the angles of the lips.

Aetiology
Angular cheilitis is most often linked to candidiasis, but is also related to the decreased vertical dimension of lower face in edentulous elderly with loss of alveolar bone; sagging of cheeks due to myotonia; sialorrhoea; ariboflavinosis (with glossitis, keratitis and seborrhoea-like dermatitis); malnutrition; streptococcal infection.

angular cheilitis (kīlī´təs),

n a disease that most often occurs among the elderly but is caused by parasitic fungi, along with bacterial involvement, or a deficiency in vitamin B rather than age; angular cheilitis appears as skin lesions on the lips, particularly as breaks in the tissue at the corners of the oral cavity (commissures). Often occurs in conjunction with reduced mobility and strength in the oral cavity. See perlèche.
