ANGULAR
CHELITIS
Angular
cheilitis (also called perlèche, cheilosis or angular stomatitis) is an inflammatory
lesion at the labial commissure, or corner of the mouth, and often occurs
bilaterally. The condition manifests as deep cracks or splits. In severe cases,
the splits can bleed when the mouth is opened and shallow ulcers or a crust
may form.
Although
the disease has an unknown etiology, the sores of angular cheilitis may become
infected by the fungus Candida albicans (thrush), or other pathogens. Studies
have linked the initial onset with nutritional deficiencies, namely vitamin
B (Riboflavin B2 and Cyanocobalamin B12[ and iron deficiency anemia, which
in turn may be evidence of poor diets or malnutrition (e.g. celiac disease).Cheilosis
may also be part of a group of symptoms (upper esophageal web, iron deficiency
anemia, glossitis, and cheilosis) defining the condition called Plummer-Vinson
syndrome (aka Paterson-Brown-Kelly syndrome).Angular cheilitis occurs frequently
in the elderly population who experience a loss of vertical dimension due
to loss of teeth, thus allowing for over-closure of the mouth.Less severe
cases occur when it is quite cold (such as in the winter time), and is widely
known as having chapped lips. This lesser form mostly happens to young children/teenagers.[citation

moment of relief, only serving to worsen the condition.(1)
