Dyshidrosiform bullous pemphigoid is a variant of bullous pemphigoid. At least 84 patients with dyshidrosiform bullous pemphigoid have been described. Dyshidrosiform bullous pemphigoid usually presents with pruritic blisters in elderly individuals; the hemorrhagic or purpuric lesions on the palms and soles can be the only manifestation of the disease. However, bullae may concurrently or subsequently appear on other areas of the patient's body. Patients typically improve after the diagnosis is established and treatment is initiated. The mainstay of therapy is systemic corticosteroids, with or without topical corticosteroids, and systemic dapsone or immunosuppressants. Drug-related or nickel-induced dyshidrosiform bullous pemphigoid improves after stopping the associated agent; however, systemic therapy has also been required to achieve resolution of the blisters. Similar to classic bullous pemphigoid, neurologic conditions and psychiatric disorders have been observed in dyshidrosiform bullous pemphigoid patients. The new onset of recurrent or persistent blisters on the palms, soles, or both of an elderly individual should prompt the clinician to consider the diagnosis of dyshidrosiform bullous pemphigoid.
