Primary Hodgkin disease of the spine could mimic eosinophilic granuloma initially

Primary Hodgkin disease （HD） of bone is rare. The recognition on it is relatively confined. Bothcases arising-in male adults were suspected to be Potts disease （spinal tuberculosis） on imaging, and pathologic misdiagnosed initially. The clinical situations rapidly aggravated. The pathomorphology was remarkable malignant changed. They shared similar process in clinical, radiological and diagnostic process and could be representative. We retrospectively analyzed correlative results of them and review points of distinction from other disease entities that might be confused with it.

Color Doppler sonography and angioscintigraphy in hepatic Hodgkin's lymphoma

AIM： To estimate the characteristics of Color Doppler findings and the results of hepatic radionuclide angiography （HRA） in secondary Hodgkin＇s hepatic lymphoma. METHODS： The research included patients with a diagnosis of Hodgkin＇s lymphoma with metastatic focal lesions in the liver and controls. Morphologic characteristics of focal liver lesions and hemodynamic parameters were examined by pulsed and Color Doppler in the portal, hepatic and splenic veins were examined. Hepatic perfusion index （HPI） estimated by HRA was calculated. was observed. Lesions were mostly hypoechoic and mixed, solitary or multiple. Some of the patients presented with dilated splenic veins and hepatofugal blood flow. A pulse wave was registered in the centre and at the margins of lymphoma. The average velocity of the pulse wave was higher at the margins （P 〉 0.05）. A continuous venous wave was found only at the margins of lymphoma. There was no linear correlation between lymphoma size and velocity of pulse and continuous wave （r = 390, P 〈 0.01）. HPI was significantly lower in patients with lymphomas than in controls （P 〈 0.05）, pointing out increased arterial perfusion in comparison to portal perfusion. CONCLUSION： Color Doppler ultrasonography is a sensitive method for the detection of neovascularization in Hodgkin＇s hepatic lymphoma and estimation of its intensity. Hepatic radionuclide angiography can additionally help in the assesment of vascularisation of liver lesions.

Classical Hodgkin＇s Lymphoma Presenting as Acute Hepatic Failure One Case Report

A 20-year-old boy presenting daily febrile episodes was suspected to have developed acute hepatic failure. Serologic tests ruled out infectious and autoimmune causes apart from drug toxicity. During clinical examinations, he was found to have generalized enlarged lymph nodes that were then taken biopsy. It was diagnosed as classical Hodgkin＇s lymphoma based on histological examination of the lymph node. A bone marrow biopsy showed marrow infiltration by Hodgkin＇s lymphoma with hemophagocytosis and secondary myelofibrosis. A percutaneous liver biopsy demonstrated hepatic involvement of the same disease. After an extensive work-up, the cause of liver failure was figure out to be only attributed to the involvement of the lymphoma. Hodgkin＇s lymphoma as a cause of hepatic failure is rare and young patients diagnosed as Hodgkin＇s lymphoma causing hepatic failure has been reported very rarely so far.

Non-Classical Hodgkin＇s Lymphoma Presenting As Cauda Equina Syndrome a Rare presentation： One Case Report

Nodular lymphocyte predominant Hodgkin＇s disease occurs in 5% of all cases of Hodgkin＇s disease. It occurs more commonly in male. Only 5% of all Hodgkin＇s lymphoma cases develop spinal cord compression and in only 0.2% cases, spinal cord compression occurs as the initial presentation. So our case is rare both in the form of the unique variety of Hodgkin＇s disease and also in the form of presentation.

Immunotherapy in the treatment of lymphoma

Relapsed or refractory non-Hodgkin’s lymphomas,especially diffuse large B-cell lymphoma as well as relapsed or refractory Hodgkin lymphomas are hard-to-treat diseases.Patients who do not respond to initial therapy or experience relapse are treated with salvage regimens,and if eligible for aggressive therapy,treatment is continued with high-dose chemotherapy and autologous stem cell transplantation.Current therapy options can cure substantial numbers of patients,however for some it is still an uncurable disease.Numerous new drugs and cell therapies are being investigated for the treatment of relapsed or refractory lymphomas.Different types of immunotherapy options have shown promising results,and some have already become the standard of care.Here,we review immunotherapy options for the treatment of lymphoma and discuss the results,positions,practical aspects,and future directions of different drugs and cellular therapies for the treatment of this disease.

A study of Hodgkin/Reed-Sternberg cells using single cell polymerase chain reaction

OBJECTIVE: To investigate the characteristics of Hodgkin/Reed-Stemberg (H/R-S) cells found in patients with various types of Hodgkin's disease (HD). METHODS: H/R-S cells were micropicked from frozen sections of tissues affected by HD. The DNA from these cells was amplified by polymerase chain reaction (PCR) using immunoglobulin heavy chain gene FR III a/JH primers and light chain gene family-specific primers. RESULTS: A total of 52/135 (35.8%) isolated cells showed the specific products in the reactions. IgH and V kappa 4 rearrangements were repeatedly found in many cells from a lymphocyte predominance type sample; repeated V kappa 4 and individual IgH/V kappa 2,4 rearrangements and individual IgH, V lambda 3/ V kappa 4 rearrangements were found in two different cases of the nodular sclerosis type; repeated IgH/ V lambda 3 and individual V lambda 2,4 rearrangements, repeated V kappa 2,4 rearrangements, repeated V kappa 4 and individual IgH/ V kappa 3 rearrangements, repeated IgH and individual V kappa 3/ V lambda 4 rearrangements were detected in 3 cases of the mixed cellularity type. Repeated and individual IgH rearrangements were found in other 2 cases. CONCLUSION: The H/R-S cells isolated from the lymphocyte predominance subtypes of HD have IgH and V lambda 4 gene rearrangements. This suggests that the lymphocyte predominance type is a proliferation of neoplastic B cells. The cells isolated from the mixed cellularity and nodular sclerosis types derive from B lineage cells at various stages of differentiation because of the presence of their IgH, kappa and/or lambda gene rearrangements. To our knowledge, this is the first time that the lambda gene rearrangement was detected in H/R-S cells.
