Abstract
Pemphigus vulgaris is an autoimmune mucocutaneous disease in which the oral lesion is generally the first manifestation of the pathology. The objective is to report a case diagnosed by the dentist to help reduce potential damage of this disease. A 38-year-old white male patient went to a dermatologist because of complaints about multiple ulcers with 2-year evolution. In general physical examination, ulcerated lesions were observed in the torso and upper limbs. On intraoral examination, erythematous ulcerated lesions were observed in lower lip, soft palate, and jugal mucosa. The disease hypotheses were pemphigus vulgaris, erythema multiforme, and pemphigoid. Incisional biopsy and specimen collection were executed for cytopathologic examination. The histopathologic examination exposed intraepithelial lesion and Tzanck cells. The diagnosis was pemphigus vulgaris. The patient began treatment with dermatology and has been monitored without lesions for 6 months. This report highlights the effectivity of diagnosis by oral lesions in general health treatment.
