Bullous pemphigoid and associated autoimmune thrombocytopenia: two case reports

We describe two patients with bullous pemphigoid in whom autoimmune thrombocytopenia developed. Only one case of bullous pemphigoid associated with autoimmune thrombocytopenia has previously been reported, and in that case, autoimmune hemolytic anemia was also present (Evans' syndrome). However, a wide range of other autoimmune diseases have been described in association with bullous pemphigoid, and this literature is reviewed.
