[Cannabis-induced arteritis vs. Léo Buerger disease. Nosologic discussion apropos of two new cases].

Abstract
BACKGROUND
We observed two cases of juvenile endarteritis which might suggest a possible link between Winiwarter-Buerger disease and cannabis-induced endarteritis.
METHODS
Our two patients were young men aged 18 and 20 years. Both developed acute distal ischemia of the lower or upper limbs with arteriographic evidence suggestive of Winiwarter-Buerger disease. Both smoked regularly but not excessively and both used cannabis regularly. In one case, the therapeutic response to withdrawal of cannabis was good. In the second, use of cannabis continued and arterial disease persisted.
CONCLUSIONS
The cause of Winiwarter-Buerger disease remains elusive although smoking is undoubtedly involved in the pathogenic mechanism. Our two cases recall the cannabis-induced endarteritis described in the sixties in Kif smokers in North Africa. The main clinical and radiographical features in this condition are the same as in Winiwarter-Buerger disease.
CONCLUSIONS
Winiwarter-Buerger disease and cannabis-induced endarteritis are 2 very similar conditions. The probably rare finding of juvenile endarteritis mimicking thromboangeitis obliterans should, in our opinion, be considered as a secondary and possibly toxic effect of cannabis.
