A white lesion that wipes off with gauze, leaving an erythematous base, is most consistent with which condition — and what is its treatment?
Show answer and explanation
Correct answer: C. Pseudomembranous candidiasis — treated with an antifungal such as fluconazole or nystatin
The 'wipes off' feature is the key distinguishing clue for pseudomembranous candidiasis (thrush) — true leukoplakia and lichen planus do NOT wipe off. Treatment is topical or systemic antifungal therapy (e.g., nystatin suspension/troches or systemic fluconazole).
