Disease Progression From Mucosal to Mucocutaneous Involvement in a Patient With Desquamative Gingivitis Associated With Pemphigus Vulgaris

Background: Pemphigus vulgaris (PV) frequently begins with oral lesions and progresses to skin lesions. A patient is described who developed skin lesions during follow-up and whose only initial symptom was desquamative gingivitis (DG).Methods: A 31-year-old woman presented with a 2-month history of painful gingiva. The diagnosis of PV was made according to clinical, histopathological, and immunofluorescent criteria. Topical corticosteroid (0.1% triamcinolone acetonide) was provided for the treatment of DG. Evaluation of the circulating autoantibody titers to desmoglein (Dsg)1 and Dsg3 was conducted by enzyme-linked immunosorbent assay (ELISA).Results: The gingival PV lesions went into remission with the use of topical corticosteroid, although the patient experienced occasional recurrent oral lesions that required retreatment. She had regular follow-ups and remained relatively stable for several months. However, relapse and worsening of the oral lesions and the onset of skin lesions occurred after 26 month...
