The oral mucosa becomes rigid, blanched and opaque in which of the following conditions?
Correct answer: D. Submucous fibrosis
- A. Pemphigus vulgaris
- B. Lupus erythematoses
- C. Ehlers-Danlos syndrome
- D. Submucous fibrosis
Explanation
Submucous fibrosis causes dense collagen deposition in the oral tissues, producing a stiff, blanched and opaque mucosa with restricted mouth opening. Pemphigus usually causes fragile bullae and erosions rather than rigidity.
