Successful Treatment of Pemphigus Vulgaris With the Extensive Mucocutaneous Lesions in an Elderly Patient

INTRODUCTION: Pemphigus vulgaris (PV) is a chronic and infrequent autoimmune mucocutaneous disease that is characterized by the loose blisters and erosions on the skin and mucous membrane. Middle-aged adults are affect most frequently and the elderly and juvenile cases are infrequent. Herein, we reported a case of pemphigus vulgaris in an elderly patient. CASE PRESENTATION: We reported a case of pemphigus vulgaris in a 79-year-old patient with the extensive mucocutaneous lesions. We also reviewed the literature in MEDLINE with keywords such as pemphigus vulgaris, elderly, mucocutaneous lesions, oral lesions, and treatment. DISCUSSION: We have to stress that the importance of this case report is its presentation in an elderly patient, as the frequent age of presentation in the Iranian patients is the middle age. On the other hand, PV occurs rarely, thus, the reporting of any rare case with some exceptions is important.
