Differential Diagnosis for White Discoloration on Tonsillar Region
- Single Most Likely Diagnosis
- Leukoplakia: A benign condition characterized by a white patch or plaque on the mucous membranes, often associated with chronic irritation or inflammation. The patient's asymptomatic presentation and lack of systemic symptoms make this a likely diagnosis.
