[Angioimmunoblastic lymphadenopathy--present problems]

Angioimmunoblastic lymphadenopathy is usually characterized as a lymphoproliferative disease caused by an abnormal reaction to various chemical and biological antigens and the possible development into malignant lymphomas of different types. The authors evaluate clinical and laboratory findings in a group of their patients suffering from the above disease. They emphasize the variable symptomatology, the frequently atypical course and the ensuing diagnostic difficulties.
