White patches that can be wiped off on the mucosa are characteristic of which condition?

• A. Angular cheilitis
• B. Oral leukoplakia
• C. Oral ulcers due to herpes
• D. Oral candidiasis

Answer: (D)

White, removable patches on the mucosa point to a fungal infection of the mouth, most commonly oral candidiasis (thrush). The plaques are typically curd-like and can be wiped away, leaving a red or inflamed surface beneath. This wipe-off feature helps distinguish it from other white lesions. Angular cheilitis usually shows fissures and cracking at the mouth corners rather than widespread removable plaques. Leukoplakia appears as a white patch that cannot be brushed off and may be persistent or precancerous. Herpetic ulcers from herpes are painful lesions that form vesicles and ulcers, not removable white plaques. Treatment centers on antifungal therapy and addressing any contributing factors.
