We report the case of a 57-year-old woman who developed bullous pemphi
goid 3 weeks after electron beam radiotherapy. The bullae were confine
d to the area of the radiation field and responded to topical clobetas
ol propionate 0.05% cream (Dermovate(R)). This is the second case of b
ullous pemphigoid confined to an area of previous radiotherapy. Radiot
herapy may be a rare trigger for the development of bullous pemphigoid
.
