Abstract:
Genital bullous pemphigoid (GBP) is a rare localized subset of bullous pemphigoid (BP). BP is characterized by autoantibodies against hemidesmosomes, which are involved in the structural integrity of the epidermis, and this results in subepidermal blistering. Typically, GBP affects women and children. We report an adult male who presented with a scrotal rash and blisters that developed into erosions. Only two previous cases in men have been reported. Immunofluoresence and histopathology confirmed the diagnosis of BP. The patient responded to mycophenolate mofetil and doxycycline.
