Atypical Presentation of Disseminated Varicella Zoster Virus Infection Mimicking Bullous Pemphigoid

Varicella-zoster virus (VZV) infection typically presents as a mild, self-limiting illness in children but can be severe and life-threatening in adults, particularly those who are immunocompromised. Atypical presentations, including hemorrhagic, necrotizing, and bullous forms, can complicate diagnosis and lead to delays in appropriate treatment. We present a case of a disseminated bullous VZV infection in an immunocompromised patient with cancer. The patient, initially misdiagnosed with bullous pemphigoid, was treated with oral steroids. The patient's condition progressed to acute respiratory distress syndrome, and she ultimately succumbed to the infection. This case underscores the importance of considering VZV as a differential diagnosis in immunocompromised patients presenting with bullous lesions. Early recognition and appropriate antiviral therapy are crucial for improving outcomes and preventing severe complications.
