The coexistence of psoriasis and bullous pemphigoid in 44 patients has been described in the literature. In the majority of cases no causative agent was found for the development of bullous pemphigoid, but in many cases the bullous eruption was related to antipsoriatic treatment such as PUVA, anthralin, tar and salicylic acid. ⋯ After clearing, a later exacerbation of both psoriasis and bullous pemphigoid indicated that there is a pathogenetic relationship between the diseases. Among 72 patients with bullous pemphigoid no others suffered from psoriasis.
