Which diagnostic method is used for leukoplakia?

• A. Biopsy (oral brush biopsy).
• B. CT scan of the head and neck.
• C. Blood culture.
• D. Urinalysis.

Answer: (A)

Diagnosing leukoplakia relies on tissue evaluation to determine whether the white patch has premalignant changes or early cancer. Leukoplakia is a white patch on the oral mucosa that cannot be wiped away, and a definitive assessment requires histopathology. A biopsy, including an oral brush biopsy, collects cells from the lesion for microscopic examination to look for dysplasia or carcinoma in situ. This histologic confirmation is what distinguishes benign inflammatory or reactive patches from premalignant or malignant changes. Imaging with a CT scan doesn’t diagnose leukoplakia itself; it’s used for evaluating structural involvement or staging if cancer is already suspected. Blood culture and urinalysis aren’t relevant to diagnosing mucosal white patches.
