Flagellate Dermatitis by Shiitake Mushroom

The authors present a case of flagellate dermatitis in a previously healthy young male, triggered by the consumption of shiitake mushrooms. Complete remission without complications was obtained within 7 days, simply by the application of dexamethasone cream 0.1%. Considering the growing use of this originally Asian fungus in cookery worldwide, it is likely that we will see increased occurrence of this benign and self-limited condition also in the Western world.
