Bullous pemphigoid is the most common bullous autoimmune disease and typically affects elderly individuals. The condition is characterized by tense bullae that arise on erythematous or urticarial plaques. Atypical variants include pemphigoid nodularis, pemphigoid vegetans, papular pemphigoid, erythrodermic pemphigoid, and nonbullous pemphigoid. The nonbullous subtype commonly presents with severe pruritus and other nonbullous manifestations such as urticarial plaques, erythematous patches, and erythroderma.1 True incidence is uncertain and somewhat controversial; according to a study published in the British Journal of Dermatology, about 20% of all pemphigoid patients lacked the presence of bullae at the time of diagnosis.2

Cases of nonbullous pemphigoid often go undiagnosed for many months or even years.1 Diagnosis is confirmed by immunofluorescence performed on a skin biopsy specimen as well as by immunoserology.3 Treatment is similar to that used for bullous pemphigoid with oral prednisone being the mainstay of therapy. Some cases of nonbullous pemphigoid may respond to oral doxycycline.4
