Exam 3: White Lesions

Biopsy of a lesion of the buccal mucosa shows epithelial cells with hyperchromatic and pleomorphic nuclei. Abnormal mitotic figures are found at all levels in the epithelium. The basement membrane is intact. This is consistent with:

A 42-year-old man presents with a 1 ´ 1 cm white patch on the lateral surface of his tongue. Based solely on this information, clinical differential diagnosis should include:

Although hairy tongue is often idiopathic, some cases are believed to be associated with which one of the following?

All of the following conditions affect oral and perioral tissues and are self-limiting (i.e., heal or disappear without therapeutic intervention) except:

Oral mucosal petechiae and/or ecchymoses would be a clinical sign of all the following except:

A 27-year-old man presents for a routine oral examination. Both sides of his buccal mucosa exhibit a filmy white opacity that disappears when the cheek is stretched. There is no pain, and the tissue feels normal to palpation. This would most likely be:
