For the past week, she had developed painful, tense blisters... The patient had seen her primary care doctor at symptom onset and failed to improve with topical clobetasol proprionate and hydroxyzine... Bullous pemphigoid, first identified in 1953, is the most common autoimmune blistering disorder... It has an annual incidence of 6–7 new cases per one million persons, occurs equally in men and women, and typically develops in the seventh or eighth decade of life. – The disease is characterized by IgG auto-antibodies against the basement membrane hemidesmosome, located at the dermal-epidermal junction. – Circulating and tissue-bound auto-antibodies bind to target antigens, leading to complement activation, mast cell degranulation, and the release of proteolytic enzymes along the basement membrane, ultimately leading to blister formation... Risk factors include mechanisms that disrupt the basement membrane, including ultraviolet light, radiation therapy, burns, vaccines, and surgical and accidental traumas... Certain medications have also been found to induce the disease... In the early, non-bullous phase, patients develop eczematous or urticarial lesions associated with severe pruritus, lasting weeks or months. ,– Patients eventually develop tense blisters that are localized or generalized, and may rupture., Only 10–30% of patients have oral involvement... Proposed diagnostic criteria for bullous pemphigoid include tense blisters or erosions, histologic findings of subepidermal blisters with eosinophil infiltration, and direct immunofluorescence showing linear deposits of IgG and complement along the basement membrane... It predisposes patients to secondary infections and sepsis, and mortality of bullous pemphigoid ranges 10–40% in the first year following diagnosis... Our patient was fluid resuscitated and admitted for intravenous steroids... A skin biopsy confirmed the diagnosis... She was eventually discharged home on oral prednisone and mycophenolate mofetil.
