[Human cutaneous alternariosis. 3 cases. Review of the literature (author's transl)].

The authors present 3 new cases of dermal alternariosis, associated with one Hodgkin's disease and 2 kidney transplants. Review of the other cases of literature demonstrates the pathogenicity of this saprophytic fungus which becomes opportunistic mostly in case of immuno-deficiency. Clinical aspect is usually that of papulo-nodular, ulcerative or vegetating, unique or multiple lesions of limbs and head.

[Leg ulcer. Vascular and thrombosis factors. Each responsibility of those factors? (author's transl)].

In this paper the authors try to specify the leg ulcers physiopathology. They have first studied the vascular deficits, and they are able to conclude that this deficit is not the only factor responsible for the thrombosis. They try to rediscover the factors which could lead to the thrombosis, on the created local conditions (circulatory slackening, cooling, ischemia), by using clinical and biological "check-ups" as well as an exploration of the clotting.
