Same case (hairy tongue). If biopsy were needed, what type would be used?
Show answer and explanation
Correct answer: A. Fine needle aspiration
- A. Correct. If biopsy of hairy tongue were required, an incisional biopsy (representative sample) would be used. In practice, biopsy is rarely needed as the diagnosis is clinical.
- B. Incorrect. Immunofluorescence biopsy is specifically for immunobullous diseases (pemphigus, pemphigoid).
- C. Incorrect. Excisional biopsy removes the entire lesion — not appropriate for large dorsal tongue involvement.
- D. Incorrect. FNA is for cystic lesions or lymph nodes.
