If there is a nutritional deficiency underlying the condition, various other signs and symptoms such as glossitis (swollen tongue) may be present. In people with angular cheilitis who wear dentures, often there may be erythematous mucosa underneath the denture (normally the upper denture), an appearance consistent with denture-related stomatitis. Typically the lesions give symptoms of soreness, pain, pruritus (itching) or burning or a raw feeling. Causes
Angular cheilitis is thought to be multifactorial disorder of infectious origin, with many local and systemic predisposing factors. The sores in angular cheilitis are often infected with fungi (yeasts), bacteria, or a combination thereof; this may represent a secondary, opportunistic infection by these pathogens. Some studies have linked the initial onset of angular cheilitis with nutritional deficiencies, especially of the B (B2-riboflavin) vitamin and iron (which causes iron deficiency anemia), which in turn may be evidence of malnutrition or malabsorption. Angular cheilitis can be a manifestation of contact dermatitis, which is considered in two groups; irritational and allergic. Infection
The involved organisms are:

Candida species alone (usually Candida albicans), which accounts for about 20% of cases,
Bacterial species, either:
Staphylococcus aureus alone, which accounts for about 20% of cases,
β-hemolytic streptococci alone. These types of bacteria have been detected in between 8–15% of cases of angular cheilitis, but less commonly are they present in isolation,
Or a combination of the above organisms, (a polymicrobial infection) with about 60% of cases involving both C. albicans and S. aureus.Candida can be detected in 93% of angular cheilitis lesions.
Telangiectasia macularis eruptiva perstans is persistent, pigmented, asymptomatic eruption of macules usually less than 0.5 cm in diameter with a slightly reddish-brown tinge. : 616
