[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. Its course is very capricious, not infrequently chronic and extensive. The treatment is not yet well established.
