If an unexplained white lesion persists for more than 2 weeks, what action is recommended?

• A. Biopsy
• B. Observation for 3 months
• C. Rinse with saline
• D. Prescribe antibiotics

Answer: (A)

When a white lesion in the mouth remains unexplained for more than two weeks, the next step is tissue diagnosis. The reason is that clinical appearance alone cannot reliably distinguish benign conditions from premalignant or malignant ones. A biopsy provides the histopathologic information needed to identify dysplasia or early squamous cell carcinoma and to guide appropriate treatment. Delaying further evaluation by observing for longer or trying self-care measures risks missing a potentially serious diagnosis. Rinsing with saline or prescribing antibiotics won’t yield diagnostic information and won’t address the possibility of a malignant process.
