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.
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.
perlèche/per·lèche/ (per-lesh´) inflammation with exudation, maceration, and fissuring at the labial commissures.
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; or riboflavin deficiency. Also called angular cheilitis, angular cheilosis, angular stomatitis. See also cheilitis, cheilosis.
angular cheilitisA condition characterised by inflammation, exudation, maceration and fissuring at the angles of the lips.
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.
perlecheInflammation, with fissuring, at the angles of the mouth.
an·gu·lar chei·li·tis(ang'gyŭ-lăr kī-lī'tis)
adj a general term applied to superficial fissures occurring at the angles of the oral cavity. Lesions may result from a variety of causes but most often can be related to deep labial commissures, with associated drooling, licking of the lips, unhygienic conditions, and overgrowth of bacteria, yeast, or fungi. The term has also been applied to angular cheilosis resulting from riboflavin deficiency but not to the split papule of syphilis or to herpetic lesions.
inflammation with exudation, maceration and fissuring at the labial commissures.
