title: Bullous contact allergy from cinnamon.
abstract: A young Malay female presented with a bullous eruption as a manifestation of contact allergy to cinnamic aldehyde in cinnamon. The clinical and histological features resembled bullous pemphigoid but immunological markers for pemphigoid were absent. The patient responded to a short course of oral steroids. Contact allergy can mimic pemphigoid.
