Acquired Oral Findings, continued

Angular Cheilitis (Perleche)
Angular cheilitis presents as erythema, fissures, and erosions at the corners of the mouth. May be triggered by lip-licking, sensitivity to a compound, vitamin deficiency (riboflavin), or iron deficiency. Treatment includes topical yeast treatment (Nystatin), topical antibiotic agents (Mupirocin), or low-dose topical steroids.

Leukoplakia (“White Patch”) in the Oral Cavity
In children, leukoplakia in the oral cavity is most often the result of chronic irritation, such as cheek or tongue biting. Etiologies may also include vitamin deficiency and candidiasis. In adults, especially those who are chronic tobacco users, leukoplakia is considered a pre-malignant lesion, but this is not the case for children.
Leukoplakia: A condition commonly considered precancerous in which thickened white patches of epithelium occur on the mucous membranes especially of the mouth.

Oral Hairy Leukoplakia
Oral hairy leukoplakia present as white lesions on any surface of the tongue (most often along the sides of the tongue) or on the buccal mucosa.The lesions are not painful and may be smooth and flat, irregular, and “hairyâ€� or “featheryâ€� in appearance. Benign and self-limited finding. No treatment is usually required.

 
 
Angular cheilitis is often worsened by candidal or staph superinfection.
 
Persistent or unusual leukoplakia lesions may be a sign of an underlying disorder.
 
Epstein-Barr Virus is a causative agent of oral hairy leukoplakia.
