| | Bullous pemphigoid and psoriasis vulgaris |
 | | Bullous pemphigoid is characterized by tense, subepidermal bullae with a predilection for the groin, axillae, and flexor surfaces. |
 | | The autoimmune nature of this disorder has been confirmed with the identification of IgG antibodies to bullous pemphigoid antigen 1, a 230-kd protein and bullous pemphigoid antigen 2, a 180-kd molecular weight transmembrane protein, both of which are localized to the hemidesmosome. |
 | | Bullous pemphigoid does have an increased prevalence in patients with diabetes mellitus, rheumatoid arthritis, dermatomyositis, ulcerative colitis, and myasthenia gravis; no association with malignant conditions has been noted. |
