What is a simple way to differentiate clinically between necrotic and keratotic white lesions of the oral mucosa?
b. Tolujdjne blue as a metachromatic nuclear stain
c. Fine needle aspiration
d. Prebiopsy aspiration
The correct answer is A: Necrotic lesions of the mucosa, such as
those caused by candidal infections, scrape off when gently rubbed with a moist
tongue blade. On the other hand, because keratotic lesions result from
epithelial changes, scraping fails to dislodge them.
