[Angioimmunoblastic lymphadenopathy (AILD): histology and survival time].

In order to identify histological and immunohistochemical criteria of prognostic value in AILD 40 lymph nodes with typical and 15 cases with incomplete features were semiquantitatively analyzed. Their expression were correlated with survival data of all patients. Significant prognostic value could be detected for following parameters: mitoses, immunoblasts, CD 30-positive blasts, multinuclear tumor cells and eosinophilic granulocytes. However residual lymph node structures, venules, PAS-positive material, and reticulum cells did not correlate with survival data. The short median survival time does not justify AILD grouping as low grade malignant lymphoma.
