Photo Quiz: Can You Identify These Oral and Perioral Lesions?
What approach would you take?
Case 1: Consultation with a dentist confirmed that the lesion was caused by irritation from a roughened right upper central incisor, resulting in leukoplakia lingualis with ulceration. The offending tooth was smoothed; the ulcer and leukoplakia subsequently resolved.Leukoplakia is a common, potentially malignant oral lesion that is more frequently seen in men than in women. There are 4 types1:
- Simple leukoplakia may be associated with repetitive trauma, as in this patient.
- Atypical leukoplakia features dysplasia and thickening of the epithelium; often, keratinization is present.
- Stomatitis nicotina is associated with pipe smoking.
- Leukoedema is characterized by wrinkling of the affected area, which may also appear waterlogged from edema.
Unless leukoplakia is associated with tertiary syphilis, chronic irritation, smoking, or alcohol( abuse, the cause is usually unknown. Treatment consists of removal of the inciting agent or, if the lesion is atypical, surgical excision of the affected area.

Case 2: The rash was diagnosed as steroid-exacerbated perioral dermatitis. Acne vulgaris, rosacea, and tinea facei were also considered in the differential. Acne was unlikely because of the absence of comedones and pustules; rosacea specifically spares the area affected in this patient; and tinea facei was ruled out by a potassium hydroxideevaluation.
The culprit corticosteroid was immediately discontinued; oral tetracycline, given for 2 months, resolved the dermatitis.
Widespread application of a topical corticosteroid to dermatitis on the face can lead to a more extensive rash; the periocular areas are especially susceptible. Caution your patients to avoid the use of high-potency corticosteroids on the face unless the preparation is specifically prescribed.
