[Angioimmunoblastic lymphadenopathy with dysproteinemia. The first reported case at the "Santo Tomás" Hospital]

Description of the first case of angio-immunoblastic lymphadenopathy with dysproteinemia diagnosed in a male patient 64 years old and which preceded the development of a lymphoma. The importance of this study is the association that may exist between certain drugs and the development of angioimmunoblastic lymphadenopathy, which occurred in our patient with the use of diphenylhydantoin. This disease can present itself up to 22 years after exposure to the agent.
