title: Gentamicin: systemic exposure to a contact allergen.
abstract: A case is presented of an allergic dermatitis provoked by intravenous gentamicin in a patient previously sensitized by topical medications. Patch tests confirmed hypersensitivity to gentamicin and neomycin. The nature of reactions to contact allergens given systemically and the nature of cross-reactions between aminoglycoside antibiotics are reviewed.
