How are lesions of pemphigus appearance?

• Intact bullae are rare in the mouth • More commonly, patients have ill-defined, irregularly shaped, gingival, buccal, or palatine erosions, which are painful and slow to heal • The erosions extend peripherally with shedding of the epithelium • Erosions may spread to involve the larynx, with subsequent hoarseness. The patient often is unable to eat or drink
