Oral presentation of pemphigus vulgaris and its response to systemic steroid therapy.

This article reviews our experience during a 20-year period with patients with oral lesions of pemphigus vulgaris. Of the 30 patients, 20 were women and 10 were men, with an age range of 24 to 68 years. The soft palate was involved in 80% of cases at initial presentation. Direct immunofluorescence studies were positive for IgG in the intercellular region in all cases where lesional tissue was histologically studied. Systemic steroid therapy alone controlled the disease in 24 patients, one patient was given no treatment, and the remaining five required additional treatment with either azathioprine, cyclophosphamide, or gold. Steroid therapy was continued in the long-term at a reduced dose, but side effects such as diabetes mellitus, hypertension, and duodenal ulcers were observed. Long-term steroid therapy is therefore the treatment of choice for the oral lesions of pemphigus vulgaris, but in some cases alternative treatment options may be required.
