About Oropharyngeal Candidiasis

Fungal infections of the oral mucosa are most frequently caused by Candida species, with C. albicans being the most common species associated with such infections. Oropharyngeal candidiasis is commonly found in immuno-compromised patients, including HIV and cancer patients, and in other chronic disease states such as diabetes. For instance, oropharyngeal candidiasis is the most frequently occurring infection in head and neck cancer patients undergoing radiation therapy. The clinical presentation of oropharyngeal candidiasis is variable with symptoms including soreness, burning, and/or altered taste. The signs of clinical candidiasis usually include white pseudomembraneous plaques and patches (thrush), erythematous lesions or occasionally angular cheilitis. Left untreated, the condition may progress to involve the esophagus or to more serious systemic complications.
