[Dermatosis caused by bone graft material (author's transl)].

: Cases of dermatosis caused by surgical implants are not infrequently observed. They are represented by many clinical forms. The pathology slides most often reveal a more or less dense dermal infiltration associated with signs of allergic angeitis. The pathophysiology is described as an intermediate or retarded hypersensibility or continuous non-specific antigen stimulation. The diagnosis is confirmed by the cure following removal of the surgical implants since the epicutaneous tests are not always fiable. We noted two patients whose clinical profile ressembled that of hematodermie.
