[Thrombotic thrombopenic purpura associated with Hodgkin's disease].

We report the second case of Hodgkin's disease associated with thrombotic thrombocytopenic purpura (TTP). Although the two diseases coexisted originally, TTP was diagnosed alone at first. Because of the very rare occurrence of this association the diagnosis of TTP is discussed according to the accepted criteria and taking into account the haematological complications which can reveal or be observed in Hodgkin's disease. No evident relationship between the two diseases can be suggested. But immunologic disorders observed in the two cases suggests that their coexistence is not necessarily accidental. The evolution of these two diseases is particularly good.
