Perioral dermatitis, also known as periorificial dermatitis, is a common type of inflammatory skin rash. [2] Symptoms include multiple small (1–2 mm) bumps and blisters sometimes with background redness and scale, localized to the skin around the mouth and nostrils. Less commonly, the eyes and genitalia may be involved. [3]
Redness around the lips in circumoral distribution with dryness and scale is typical. [4] [15] Chapping may also occur, especially in cold weather. [16] If symptoms worsen due to persistent licking, cracked lips can occur usually on the lower lip. [5] Observation of the person's habitual behavior can also be a sign and symptom of lip licker's ...
Oral cancer, also known as oral cavity cancer, tongue cancer or mouth cancer, is a cancer of the lining of the lips, mouth, or upper throat. [6] In the mouth, it most commonly starts as a painless red or white patch , that thickens, gets ulcerated and continues to grow.
Perioral dermatitis is a rash typically around the mouth, that spares the vermilion border. [10] Cheilitis glandularis may present with a burning sensation over the vermilion border. This chronic progressive condition is associated with thinning of the skin of the lips and ulceration. [11]
Angular cheilitis is thought to be a multifactorial disorder of infectious origin, [10] with many local and systemic predisposing factors. [11] The sores in angular cheilitis are often infected with fungi (yeasts), bacteria, or a combination thereof; [8] this may represent a secondary, opportunistic infection by these pathogens.
Denture-related stomatitis is a common condition where mild inflammation and redness of the oral mucous membrane occurs beneath a denture. In about 90% of cases, Candida species are involved, [ 4 ] which are normally a harmless component of the oral microbiota in many people.
Red, erosive or ulcerative lesions indicate atrophy, loss of epithelium and inflammation. [7] Early, acute lesions may be erythematous (red) and edematous (swollen). [ 2 ] With months and years of sun exposure, the lesion becomes chronic and may be grey-white in color and appear dry, scaly and wrinkled.
The origin of the lesion is unclear. This condition appears to be of an inflammatory nature. [7]An excessive denture palatal relief area, creating a void between the denture base and the tissue of the palate, encourages food entrapment and so encouraging bacterial and fungal growth between the two surfaces.
