Oral pemphigus vulgaris preceding cutaneous lesions: Recognition and diagnosis

Background. Pemphigus vulgaris, or PV, is a potentially life-threatening illness that manifests itself initially in the mouth in the majority of patients. Paradoxically, it is less commonly recognized when it involves lesions on the oral mucosa rather than on the skin. Case Description. This article describes the clinical presentation of 42 cases of oral PV evaluated and diagnosed by dentists. Emphasis is placed on the common distribution and appearance of oral PV lesions and diagnosis of the disease. Clinical Implications. The dentist has a unique opportunity to recognize the oral presentation of PV and contribute to an early diagnosis and, therefore, an improved treatment outcome.
