title: [Allergic vasculitis caused by vitamin B6].
abstract: A patient developed extensive bulloushaemorrhagic lesions on the lower legs after taking analgesic preparations. Allergologic tests yielded an Arthus-type reaction with vitamin B6. The histological and immunofluorescence examination of a lesional and test site biopsy showed the picture of a superficial and deep vasculitis with deposits of C3 at the basement membrane of dermal venules.
