A patient taking prolonged antibiotics develops a white lesion on the palate that can be wiped off. What type of candidiasis is this?
Show answer and explanation
Correct answer: B. Pseudomembranous candidiasis
- A. Hyperplastic candidiasis presents as a WHITE patch that CANNOT be wiped off — it is adherent. Distinct from pseudomembranous.
- B. Pseudomembranous candidiasis (thrush) presents as REMOVABLE white plaques that wipe off, revealing an erythematous base. It classically follows antibiotic use (disrupts normal flora). The white material consists of Candida hyphae, desquamated epithelial cells, and inflammatory cells.
- C. Erythematous candidiasis presents as a RED flat lesion — not as a white wiping-off lesion. It often appears as redness under dentures.
- D. Angular cheilitis affects the corners of the mouth — not the palate — and presents as cracking, not removable white plaques.
