Abstract
The behcet disease is a vasculitis with polyorganic attacks whose diagnosis is established by
the international study group for behcet disease (ISGBD).
The arterial ulcer or aphta has no diagnostic value in the criteria of ISGBD.
its morphological similarity and most likely pathophysiological also, with bipolar ulcers
deserves attention.
This article is an observation relating the history of a patient who does not respond to criteria
of ISGBD despite the presence of an arterial aphta.
The tradive occurrence of minor criterion was a cause of diagnostic and therapeutic delay.
