Answer

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.

The mucous membranes most often affected in pemphigus vulgaris are those of the oral cavity, which is involved in almost all patients with pemphigus vulgaris and sometimes is the only area involved. Erosions may be seen on any part of the oral cavity. Erosions can be scattered and often are extensive. Erosions may spread to involve the larynx, with subsequent hoarseness. The patient often is unable to eat or drink adequately because the erosions are so uncomfortable.

In juvenile pemphigus vulgaris, stomatitis is the presenting complaint in more than 50% of the cases.

Other mucosal surfaces may be involved, including the conjunctiva, [2] esophagus (causes odynophagia and/or dysphagia), [3] labia, vagina, cervix, vulva, [4] penis, urethra, nasal mucosa, and anus.
