    Abstract:
    INTRODUCTION: In recent years important advances have been made in the understanding of angioimmunoblastic lymphadenopathy since substantial controversy has been related to the name, course, prognosis and therapy of the disease. It was first recognized in the Kil Classification as a low risk T-cell lymphoma [5], and omitted from the most widely used Working Formulation for clinical purposes. According to the criteria of REAL (Revised European American Lymphoma), classification angioimmunoblastic lymphadenopathy (AILD) is one of peripheral postthymic T cell lymphomas that are an immunologically defined category of non-Hodgkin's lymphomas originating from the peripheral lymphatic tissues. Morphologically, AILD is characterized by partially or completely obliterated sinuses and frequent infiltration of the pericapsular tissue and substantial proliferation of epithelioid, postcapillary venules. Cytologically, polymorphous cellular infiltration with immunoblasts, transformed lymphoid cells, polyclonal plasma cells, eosinophils and epithelioid cells are found. Clinically, rapid occurrence of systemic symptoms in elderly individuals (sixth and seventh decades of life) with generalized lymphadenopathy, hepatosplenomegaly and cutaneous maculo-papulous or erythematous rash is noted. The patients are characterized with hyperimmune condition in the form of Coombs' positive haemolytic anaemia, polyclonal hypergamma-globulinaemia and liability to infections [8, 9]. In spite of numerous suggestions, therapeutic consensus has not been achieved, and the reported survival ranges from 1 to 30 months [10, 11]. Therefore, this information suggests an aggressive form of the disease with the 60% mortality rate. METHODS: At the Institute of Haematology of the Clinical Centre of Serbia in Belgrade in the last five years, from 1993 through August 1998, nine patients were diagnosed with AILD according to the results of pathohistological examination of the extirpated peripheral lymph nodes and the correlation with clinical picture and relevant laboratory findings. RESULTS: Clinical characteristics of nine patients in whom AILD was diagnosed after lymph node biopsy are given in Table 1. The group consisted of 6 men and 3 women, mean age 53. Eight patients were in advanced stage of the disease at the time of the diagnosis (III and IC CS), while the patient in II CS stage had a large tumorous mass (M+). All patients had initial systemic symptoms. Five of them developed fever with chills. Three patients had evidence of extranodal infiltration of the bone marrow. Infiltration of the liver was suspected in two patients according to aberrant hepatogram values, although pathohistological verification was not obtained. In one patient lung infiltration was histologically verified in addition to bone marrow and liver infiltration. All patients had peripheral lymphadenopathy, and most of them hepatosplenomegaly, as well. Three patients had the so called bulky form of the disease since the diameter of the largest tumour exceeded 10 cm. On admission, most were in poor overall condition, and only two were apparently healthy. Knowing that AILD is basically an immunoregulatory disease and that the described cases of association with systemic diseases of the connective tissue and some drugs were implied in the triggering of AILD, Table 2 shows important information obtained form histories of these patients. Namely, 7 of 9 patients had cutaneous changes suggestive of erythematous or maculopapular rash, while three had received corticosteroid therapy for months before AILD was diagnosed since toxoallergic exanthema had been incorrectly suspected. Three patients received gold sodium thiosulfate therapy for rheumatoid arthritis, while four had history of allergy to drugs and pollen. Table 3 shows laboratory results: anaemia was present in 8 of 9 patients, it was severe in three with haemoglobin values of 67 g/L, 72 g/L and 50 g/L, respectively. Five patients had haemolysis. A
