Primary follicular immunoblastic lymphoma (FIBL) is an extremely rare lymphoma. The positive expression of CD10 suggests the lymphoma originating from germinal centers (GC) and CD138-positive expression generally indicates plasmablastic or plasmacytic differentiation. We report such a rare case in a Chinese female patient and analyze the clinicopathologic and immunohistochemical features of this disease. PET-CT examination was performed to detect signs of systemic lymph node metastasis. We also discussed the differential diagnosis of FIBL from follicular lymphoma (FL) and reactive follicular hyperplasia (RFH). As a rare variant of human follicular lymphoma, FIBL is featured by a neoplastic overgrowth of intrafollicular immunoblasts. Compared with FL, FIBL has a greater chance to evolve into diffuse large B-cell lymphoma with therefore a poorer prognosis.

There are various complex formations between immunoglobulin and serum enzymes in the body. Of these, LD-Immunoglobulin complex is most common. It has reported that LD-IgG or LD-IgA complex existed in the serum of healthy person or many patients who have various clinical disorders. The clinical significance of complexes is not known, but it results in the increase of total LD activity and interference to the LD isoenzyme electrophoresis interpretation due to its anomalous pattern. We have reported a case of LD-Immunoglobulin complex in AILD(Angioimmunoblastic lymphadenopathy with dysproteinemia) with reference. The patient was admitted with fever, chills and cervical LN enlargement, in LN biopsy, diagnosed AILD, and during treatment expired by sepsis. Since admission, serum total LD activities were increased and serum LD isoenzyme EP showed that LD3-5 fractions was not separated in broad single band. Its pattern was due to LD-immunoglobulin complex, LD-bound immunoglobulin was IgG ,lamda. For the identification of immunoglobulin, we at first did serum protein immunoelectrophoresis. then stained the plate with tetrazolium dye for LD activity.

We report here a case of angioimmunoblastic lyinphadenopathy with dysprote inemia(AILD) in a 65-year-old male associated with skin nodules on the face. Physical examina.tion showed generalized lymphadenopathy, hepatosplenomegaly, erythematous maculopapular eruptions on the trunk and extremities, and er the matous nodules on the face. Lahoratory findings showed hemolytic anernia, arid polyclonal gammopathy. Histopathological findings of lymph node revealed typical features of AILD. I-iistopathological findings of maculopapules revealed lymphohistiocytic infiltra tion and extravasated erythrocytes around the blocked vessels, whereas histological picture of nodules on the face mirrorred that of the lymph node. After taking systemic chemotherapy, his general condition and skin lesions were improved.

Peripheral T-cel1 lymphoma(PTCL) encompasses histopathologically and clinically various spectra of cutaneous T-cell lymphoma(CTCL). In this report, we describe two cases of PTCL showing diRerent clinical courses according to EBV(Epstein-Barr virus) positivity. The chnical course of case 1 with EBV-associated PTCL was rapidby fatal and refractory to intensive chcmotherapy. However, in case 2, EBV genomes were not found in her lesional tissues and she showed an indolent clinical course withoaat systemic symptoms. Accordingly, serological and immunohistochemical investigations for EBV might be mandatory in cutaneous PTCL to evaluate clinical prognosis.

This study was purposed to investigate the EBV infection status of lymphoma patients from January 2008 to April 2012 in the First Hospital of Peking University. All the candidates have been detected for EBV which was either peripheral blood EBV DNA or ISH EBER in pathology from January 2008 to April 2012. The information on their sex, age, pathological type, peripheral blood EBV DNA and ISH EBER was collected, the positive rate of different EBV tests was studied, and the different characteristics of the EBV(+) and EBV(-) group were also explored. And Kaplan-Meier and Cox survival analysis was applied to investigate the EBV's effect on overall survival of these patients. The results showed that among 169 lymphoma patients, the positive rates of EBV EBER in extranodal NK/T cell lymphoma, angioimmunoblastic T cell lymphoma and peripheral T-cell lymphoma were 84.8%, 72.7% and 40.0%, respectively, and were ranged as the top three. The positive rate of EBV in DLBCL was relatively lower (16.7%) than that in above three types of lymphoma. The positive rate of peripheral blood EBV DNA of the elderly EBV(+) DLBCL was 50%. One out of 10 HL patients was subjected to EBER detection, the result of which was positive. The positive rate of peripheral blood EBV DNA of HL was 10%. Both the T cell lymphoma proportion and the rate of B symptom were higher in EBV(+) group than in EBV(-) group. In all the EBER(+) cases, the difference of OS between EBV(+) and EBV(-) patients was statistically significant. In multiple-factor survival analysis, peripheral blood EBV DNA positive was an independent risk factor for poor prognosis in the patients with lymphoma. It is concluded that EBV is closely related to extranodal NK/T cell lymphoma, angioimmunoblastic T cell lymphoma and peripheral T-cell lymphoma. Peripheral blood EBV DNA positive is an independent risk factor for poor prognosis in lymphoma patients.
