title: Hypersensitivity to rat saliva.
abstract: A patient who rapidly developed impressive local edema around a rat bite site is described. An interesting differential diagnosis was presented since the offending rat was experiencing an opiate withdrawal syndrome. A discussion of the possibilities of animal product allergy, local infection, and edema produced by opiate histamine releasers was considered.
