unusual presentations of bullous pemphigoid in young patients: a case series

Introduction: bullous pemphigoid (bp) is the most common subepidermal autoimmune vesiculobullous disorder. it mainly affects the elderly, with a mean age at presentation of 69 to 83 years and an incidence of 7 to 43 per million population in european studies. bullous pemphigoid (bp) is rarely encountered in young people, with an incidence rate of less than 0.5 cases per million population in individuals less than 50 years. case presentation: a 28-year-old male presented with fluid-filled lesions over his right forearm for three days. also, an 18-year-old male presented with fluid-filled lesions over his face, hands, groin, and legs for two months. in both cases, histopathology and direct immunofluorescence confirmed bp. conclusions: though bp is rare in young individuals, it should be considered one of the differentials of vesiculobullous disorders. herein, we reported two cases of bp in young people at unusual sites.
