[Sarcoidosis and sarcoid reaction associated with Hodgkin's disease].

The authors report a case of Hodgkin's disease associated with pulmonary and mediastinal sarcoidosis, and they recall the frequency of sarcoid reactions in lymphoma, notably in Hodgkin's disease. The Hodgkin's disease-sarcoidosis association is much less common and sometimes raises difficult diagnostic problems. The physiopathological mechanisms that are possibly involved are analyzed.
