From a biochemistry point of view, Biotin or vitamin B7, previously also known as vitamin H, possesses a simple chemical structure; thus it is quickly metabolized and addressed to its biological tasks. For that reason, probably, no case report of immediate- and delayed-type reactions are described in the literature. Just two cases of occupational allergic contact dermatitis to biotin and biotin precursors have been reported.

Keywords: Allergic Contact Dermatitis, Biotin, Occupational Exposure, Vitamin B7, Vitamin H.
