Title Occupational protein contact dermatitis from shiitake mushroom and demonstration of shiitake-specific immunoglobulin E
Bibliographic information Oct. 2005, Vol.53, No.4, p.211-213. Illus. 10 ref.
Abstract Shiitake are popular edible mushrooms all over the world. There are no previous reports of protein contact dermatitis (PCD) from shiitake, and there is only a single report of shiitake-specific immunoglobulin E (IgE). Two cases of shiitake growers who developed work-related eczematous eruption on their hands are described. Both of the patients had small prick test reactions to fresh shiitake, and specific IgE to shiitake was detected in their sera by immunospot. One of the patients had a large prick test reaction to dry shiitake and also a positive wheal reaction to fresh shiitake in an open application test. Neither of the patients had noticed any symptoms of contact urticaria at work. Both of the patients had immediate IgE-mediated allergy to shiitake, and the diagnosis of occupational PCD was made. There are no commercial in vitro tests for shiitake-specific IgE. It is therefore important to test for immediate allergy when shiitake contact dermatitis is suspected.
