Abstract
Angioimmunoblastic T-cell lymphoma (AITCL) is a rare, aggressive lymphoma which derives from follicular helper T cells, commonly affecting the elderly population. It accounts for 2% of all non-Hodgkin lymphomas, with a reported 5-year overall survival rate of less than 30%. Very often, the clinical picture of AITCL encompasses systemic symptoms such as generalized lymphadenopathy, hepatosplenomegaly, skin rash, anemia, and polyclonal hypergammaglobulinemia. Here we report on the case of a female patient who presented with clinical features resembling drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) prior to the definitive diagnosis of AITCL. The index of suspicion for cutaneous manifestations of lymphoma, and especially AITCL, must be high, particularly in atypical clinical courses of drug eruptions or if skin lesions relapse and are refractory to standard high-dose systemic corticosteroids.

Abstract
Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive peripheral T-cell lymphoma typically characterized by prominent lymphadenopathy and B-symptoms at the time of presentation, polyclonal hypergammaglobulinemia, autoimmune hemolysis and frequent but highly variable involvement of Epstein-Barr virus (EBV). Lymph node biopsy findings typically include effacement of nodal architecture, polymorphic infiltrate, atypical T-cells (usually CD4+/CD10+/PD1+) and prominent proliferations of high endothelial venules and follicular dendritic cells. However, this classic constellation of pathologic findings is often initially obscured by a prominence of EBV+ B-immunoblasts with or without associated peripherally circulating EBV DNA. Here we document the first reported case of an acute serologic EBV profile (VCA-IgM) in a patient with AITL, and we recommend that clinicians maintain a high index of suspicion for AITL in the appropriate clinical scenario, irrespective of Epstein-Barr related findings.

Abstract
The clinical and histological presentations of angioimmunoblastic T-cell lymphoma (AITL) often mimic an infectious process. Epstein-Barr virus (EBV) and human herpes virus (HHV6) are known to be associated with AITL, but whether these viral infections play a role in its pathogenesis is unclear. It also remains to be investigated whether there might be other viruses associated with AITL. We first screened 26 well-characterised cases of AITL for herpesvirus by polymerase chain reaction (PCR) with universal primers and found evidence of only EBV and HHV6B infection. Subsequent PCR using virus-specific primers demonstrated EBV and HHV6B infection in 40/49 biopsies (36/42 cases) and 21/49 biopsies (19/42 cases) of AITL respectively with both viral infections found in 17/49 specimens (15/42 cases). Importantly, simultaneous infection with both viruses was found only in specimens showing histological pattern II (n = 2) or III (n = 15). Interestingly, among specimens containing both viruses, there was a tendency towards an inverse correlation between the EBV and HHV6B viral load as shown by quantitative PCR. In specimens positive only for EBV, the viral load was significantly higher in specimens with histological pattern III than those with pattern II. High EBV load was also significantly associated with B-cell monoclonality. Double EBV encoded small RNA (EBER) in situ hybridisation and immunohistochemistry indicated that EBV-infected B cells had a late postgerminal centre immunophenotype. Our results demonstrate an association between EBV and HHV6B infection and the histological progression of AITL, suggesting that these viruses may play a role in the pathogenesis of this lymphoma.

Abstract
Angioimmunoblastic T-cell lymphoma (T-AIL) is a peripheral T-cell lymphoma of unknown etiology. Previous clonality studies have shown a heterogeneous composition of this disease with varying restrictions of B- and T-cell populations in the tumour. For the first time in a single study and in the same pathological materials, we have analysed, lymphoid cell clonality and occurrence of human herpes viruses and Epstein Barr virus. Of 18 cases 12 (66.6%) had clonal T- and three (16.6%) had clonal B-cells. Presence of the lymphotropic viral genome of HHV6 was detected in four of 18 lymph node biopsies from T-AIL patients (22%), all were TCRgamma clonal. No HHV8 were found. Epstein Barr genome was found in 40% of cases. There was no significant association between T-cell clonality and HHV-6 or EBV infection, or between B-cell clonality and any virus infection. We conclude that T-AIL is a biologically and clinically heterogeneous entity whose true nature remains to be clarified.

Abstract
The identification of clonal rearrangements of T cell receptor (TCR) genes is central to the diagnosis of T cell lymphomas. However, in angioimmunoblastic lymphadenopathy (AILD), first described as a nonneoplastic proliferation associated with immunodeficiency, the heterogeneity of TCR and IgH gene rearrangements suggest that some cases may harbor multiple lymphoid clones. In this study we have isolated DNA from archival paraffin biopsy material from 22 cases of AILD identified on the basis of classical histological and immunohistochemical features with the aim of establishing the occurrence of clones and oligoclones, the frequency of TCR and immunoglobulin heavy chain (IgH) variable (v) gene use, and the relationship of these findings to the presence of Epstein-Barr virus. DNA extracted from the biopsies was amplified using the polymerase chain reaction (PCR) and sequenced to detect functional and nonfunctional gene rearrangements. Epstein-Barr virus-encoded short RNA species (EBERs) were detected using in situ hybridization combined with immunochemistry to identify the phenotype of the Epstein-Barr virus-infected cells. Fifty-seven clonal products were found in 20/22 patients: TCRgamma clonal products were identified in 16/22, TCRbeta clonal products in 16/22 and IgH clonal products in 6/22 cases. Oligoclonal PCR products were seen for TCR in 3/22 and for IgH in 3/22 cases. In one biopsy PCR products from all reactions were polyclonal. Sequence analysis revealed functional TCRgamma, TCRbeta, and IgH sequences in 6/12, 9/11, and 8/8 cases, respectively. Functional TCR and/or IgH oligoclones were detected in 6/20 (30%) cases. In addition, nonfunctional TCR and IgH sequences were found in 11 cases. EBERs were identified in 18/20 cases varying from occasional to 25 to 30% nuclei staining and were associated with both T and B cells, although the majority were of indeterminate phenotype. The presence of EBERs was not associated with all clonal IgH gene rearrangements but was associated with B cell oligoclones. Patterns of gene recombinations indicated that the majority of TCRgamma recombinations used GV1 and GJ1S3/2S3 genes. Six out of eleven cases used TCR BV4S1 or BV2S1 genes associated with various BJ and BD1/2 genes. No common IgH gene usage was identified, but 8 clones had varying degrees of replacement and silent mutations (0.6-10.1%), consistent with B cell clones having undergone somatic mutation in the germinal center, and 3 clones harbored unmutated V genes, consistent with naive B cells. Our data do not support the concept of AILD as a clearly defined peripheral T cell lymphoma (PTCL). Rather, they suggest that AILD as defined by histology and immunohistochemistry is either a heterogeneous entity or represents a lymphoproliferation associated with immunodeficiency in which clonal T cell or B cell proliferation may occur.

Abstract
We analyzed 33 patients with AILD T-NHL in a retrospective multicentric study. The median age was 62 yr (35-84 yr) (19 patients over 60 yr). Advanced disease (n = 31) and B-symptoms were consistently found (n = 29) and 20 patients had bone marrow involvement. The main laboratory abnormalities were: anemia (n = 13), hypereosinophilia (n = 13), lymphopenia (n = 14), hypergammaglobulinemia (n = 17), elevated lactate dehydrogenase (LDH) level (n = 24). First-line therapy was chemotherapy (ChT) alone (n = 25) or ChT after steroids (n = 8). Most patients received a CHOP-like regimen for a median number of 6 cycles and 3 patients received interferon alpha (IFN alpha) as consolidation after chemotherapy. With a median follow-up of 46 mo, 60% achieved a complete response but the outcome was poor with a relapse rate at 56%, a median survival referring to the total population was of 36 mo (2-108+ mo) and an overall survival at 5 yr of 36%. Two patients received high-dose chemotherapy (with total body irradiation) and autologous progenitor-cell transplantation for chemosensitive relapse and were free of disease at, respectively, 76 and 24 mo+. In conclusion AILD T-NHL still has a poor prognosis compared to other NHL. The role of intensive therapy and IFN alpha still remains to be evaluated.

Abstract
In this article, we have described the fine-needle aspiration biopsy (FNAB) of five cases of angioimmunoblastic lymphadenopathy (AILD). FNAB of these cases showed large number of capillary fragments, along with polymorphous population of cells consisting of plenty of immunoblasts, plasma cells, eosinophils, and mast cells. Two cases showed clusters of clear cells. It is essential to have detailed clinical features for FNAB diagnosis of AILD. Histopathology is advisable in all the fresh cases. FNAB is helpful for screening and follow-up of AILD.

Abstract
BACKGROUND In order to establish the clinico-pathological properties of angioimmunoblastic lymphadenopathy (AILD)-type T-cell lymphoma, we evaluated the type, incidence and prognostic significance of clinical and laboratory symptoms. PATIENTS AND METHODS Sixty-two consecutive patients diagnosed at the Kiel lymph node registry participated in the study. The median patient age was 64 years (range 21-87 years) and the female to male ratio was 1:1.4. Ninety percent of the patients were in stage III and IV and B-symptoms were observed in 68%. At diagnosis patients presented with skin rash (49%), pruritus (32%), edema (38%), pleural effusion (37%), arthritis (18%) and ascites (23%). Furthermore, they exhibited autoimmune phenomena such as cold agglutinines, circulating immune complexes, a positive Coombs test, smooth muscle antibodies, rheumatoid factors, immune hemolysis, a paraprotein, antinuclear antibodies and cryoglobulins. RESULTS In univariate analysis, survival was significantly related to age (p=0.032), stage (p=0.037), B symptoms (p=0.007), rash/pruritus (p=0.038), edema (p=0.030), ascites (p=0.013), number of clinical symptoms including B symptoms (p=0.004) and excluding B symptoms (p=0.017), lactate dehydrogenase (p=0.007) and hemoglobin (p=0.020). CONCLUSIONS AILD type T-cell lymphoma characteristically differs from other non-Hodgkin's lymphomas in its clinical signs and laboratory symptoms.

Abstract
In order to obtain valid data on the pattern, frequency and prognostic significance of autoimmune derangements in non-Hodgkin's lymphoma (NHL) we studied 626 consecutive adult NHL patients participating in a population-based lymphoma registry. A total of 86 patients, corresponding to 13.7%, showed autoimmune phenomena (AP). Of these, 7.8% exhibited clinical autoimmune phenomena (CAP), and 5.9% showed immunohaematological phenomena (IHP). The distribution of histological subgroups of NHL in the AP and non-AP patients was similar. The same holds true for the CAP and IHP patients. A slight, non-significant overrepresentation of NHL, T-cell phenotype was found in patients with AP. CAP preceded the diagnosis of NHL in most patients, whereas IHP was associated with active lymphoma disease. AP as a whole did not predict for time to complete response, time to relapse or for survival. The finding that IHP patients relapsed earlier than CAP patients was not reflected in a significant difference in survival.

Abstract
Since 1985 the combination of chlorambucil (10 mg daily, initially for six weeks, then alternating fortnights for 12 weeks) and interferon-alpha 2b (Schering-Plough; 2 x 10(6) U/m2 three times weekly by subcutaneous injection for 18 weeks) has been compared in a randomised trial with chlorambucil alone in previously untreated patients with stage III or IV follicular lymphoma. Responding patients have subsequently been randomised to receive maintenance interferon-alpha 2b or no further treatment. Of the 124 treated patients, 108 are evaluable for response with a median follow-up of 30 months. The major toxicity was myelosuppression which was more frequent with chlorambucil and IFN alpha 2b in combination than with chlorambucil alone (P less than 0.01). There was no treatment-related mortality. Actuarial survival at three years is 75% for all patients, regardless of therapy. There was no significant difference in response rate according to initial therapy. For the 60 patients achieving a good response to initial therapy who have entered the second part of the trial, there has been a significant prolongation of remission duration in favour of maintenance IFN-alpha 2b (median not yet reached versus two years for the 'no treatment' arm, P less than 0.015). Fewest relapses have been seen in patients who received IFN-alpha 2b throughout. Accrual to this trial continues; this preliminary analysis indicates that maintenance IFN-alpha 2b may extend remission duration in follicular lymphoma.

Abstract
Genomic rearrangement of germline T-cell antigen receptor (TcR) and immunoglobulin (Ig) genes was studied by Southern blot analysis in seven patients with angioimmunoblastic lymphadenopathy (AILD). In three cases clinically suspected of transformation into malignant lymphoma, hybridization with the TcR beta probe showed markedly dimished intensity in the 11.5 kb germline band after Eco RI digestion and normal germline configuration after Hind III and Bam HI digestion, indicating polyclonal T cell rearrangements. A clonal rearrangement of the TcR beta gene was detected in only one case at initial biopsy. No monoclonal rearrangement of Ig genes was observed. These data show that in some cases of AILD disease progression is indicated by polyclonal TcR rearrangements and not by outgrowth of a malignant clone, supporting the concept of AILD as an immunoregulatory disorder.

Abstract
Eight cases of AIL-type T-cell malignant lymphoma are reported. The clinical symptoms are the same as those described in AIL: fever, malaise, weight loss, skin rashes, polyadenopathy, and splenomegaly. However, some differences can be noted: the absence of hepatomegaly in all cases but one, the absence of polyclonal hypergammapathy in all cases but one, and predominance in females. The lymph node modifications comprise diffuse infiltrations of lymphoid cells with irregular nuclei and pale cytoplasm, associated with a large number of immunoblasts and plasma cells. Some eosinophilic granulocytes and epithelioid cells can be seen. Hyperplasia of the vessels and remnants of follicles, sometimes with proliferation of follicular dendritic cells, are prominent features. The immunolabelling study demonstrates the presence of an important T-cell population all expressing a high predominance of CD 4 phenotype. These findings are in accordance with those published in Europe and in contrast with those of some of the Japanese cases, particularly the first patients published by Shimoyama et al. The differential diagnosis with AIL is based on the presence of clusters of mainly large cells with a pale cytoplasm, on the loss of expression of one T cell marker, as in 3 cases of our series, and on the presence of a high percentage of lymphoid cells engaged in the mitotic cycle as demonstrated with the Ki 67 monoclonal antibody. However, to draw a clear cut difference between AIL-type T-cell lymphoma and AIL considered as a prelymphomatous dysimmune lymphadenopathy, only the demonstration of cytogenetic abnormalities, as in one of our cases or of rearrangement of the genes coding for beta and/or gamma chain of the antigen receptor of T-cell are valuable criteria. The follow-up of our series is not long enough to appreciate the prognosis. Three patients died, one from a glioma. All the other cases, treated with polychemotherapy show total remission with an evolution of 10 to 39 months.
