Contact dermatitis due to honeybee royal jelly.

A woman who had ingested honeybee royal jelly as a nutrient, showed an exacerbation of dermatitis when it was applied to her feet. A topical fungicide also aggravated her skin lesions. Patch testing showed positive reactions to the royal jelly, pyrrolnitrin in the fungicide and urushiol. Positive reactions to the royal jelly were found in 2 out of 10 controls, 1 of whom was sensitive to propolis.
