[Oral pemphigus].

A 33-year-old man suffered from spontaneously developing blisters at the oral mucosa. Firstly, the bullous lesions were observed in the third molar region, but they spread progressively over the buccal and palatal mucosa. The bullous lesions ruptured spontaneously, resulting in erosive lesions and pain. Before being referred to an oral and maxillofacial surgeon, the patient consulted his family doctor, his family dentist, as well as an ear-nose-throat-specialist. The oral and maxillofacial surgeon took a biopsy in order to confirm the clinical diagnosis pemphigus vulgaris. The patient was referred to a dermatologist for treatment with systemic corticosteroids and a non-steroid immunosuppressive drug. Subsequently, the mucosal lesions healed.
