title: Allergic contact dermatitis from natural latex without contact urticaria.
abstract: During the last decade, there have been many reports of immediate-type hypersensitivity to natural latex, resulting in contact urticaria, generalized allergic reactions such as urticaria and Quincke's edema, and asthmatic or anaphylactic reactions. Moreover, delayed-type hypersensitivity to rubber additives such as thiuram and carbamate derivatives is acknowledged to be the main cause of dermatitis in patients working with rubber gloves. We here report on a patient who developed severe dermatitis on his hands and forearms 3 months after he had started working with rubber gloves. Patch tests with rubber additives, skin prick tests and RAST to natural latex were negative. However, a delayed type of hypersensitivity to latex could be shown by a positive patch test. To our knowledge this is the 1st case reported of an isolated contact dermatitis from natural latex without contact urticaria to latex or hypersensitivity to rubber additives. We therefore propose that not only patch tests with rubber additives, but also skin prick and patch tests with latex should be performed in contact dermatitis patients working with rubber gloves.
