title: Allergic reaction to Patent Blue Violet during lymphography.
abstract: A case of an allergic reaction to Patent Blue Violet dye used for the purpose of lymphangiography is reported. The clinical findings were urticarial reaction, edema of the eyelids and lips, and hypotension. Previous sensitization to triphenylmethane dyes, in drugs and other chemicals was likely, but not proven. Such commonly used compounds have been compiled in a Table. History of a previous hypersensitivity reaction to these compounds is not a contraindication for lymphangiography but should call for emergency planning and possible premedication.
