Common oral lesions: Part I. Superficial mucosal lesions.
Common superficial oral lesions include candidiasis, recurrent herpes labialis, recurrent aphthous stomatitis, erythema migrans, hairy tongue, and lichen planus. Recognition and diagnosis require taking a thorough history and performing a complete oral examination. Knowledge of clinical characteristics such as size, location, surface morphology, color, pain, and duration is helpful in establishing a diagnosis. Oral candidiasis may present as pseudomembranous candidiasis, glossitis, or perlèche (angular cheilitis). Oral candidiasis is common in infants, but in adults it may signify immune deficiency or other illness. Herpes labialis typically is a mild, self-limited condition. Recurrent aphthous stomatitis most often is a mild condition; however, severe cases may be caused by nutritional deficiencies, autoimmune disorders, or human immunodeficiency virus infection. Erythema migrans is a waxing and waning disorder of unknown etiology. Hairy tongue represents elongation and hypertrophy of the filiform papillae and most often occurs in persons who smoke heavily. Oral lichen planus is a chronic inflammatory condition that may be reticular or erosive. Certain risk factors have been associated with each of these lesions, such as poor oral hygiene, age, tobacco use, and alcohol consumption, and some systemic conditions may have oral manifestations. Many recommended therapies for oral lesions are unsupported by randomized controlled trials.
