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., Competing Interests: The authors have no conflicts of interest to declare. There were no financial interests (stocks, patents, employment, honoraria, or royalties) or nonfinancial relationships (political, personal, or professional) that may be interpreted as having influenced the writing of this paper.
