NK/T-cell lymphomas which are characterized by the biphenotype of the NK-cell and the T-cell are divided into nasal and non-nasal NK/T-cell lymphoma, non-nasal NK/T-cell lymphoma is then further subdivided into primary cutaneous and 4 subtypes of secondary cutaneous lymphoma such as nasal type, aggressive, blastic(blastoid), and other specific NK-like T-cell lymphoma. Primary cutaneous NK/T-cell lymphoma is a very rare condition and defined as a lack of extracutaneous disease for at least 6 months from the time of diagnosis. We herein report a case of non-nasal NK/T-cell lymphoma, which is consistent with primary cutaneous type.

The radiologically detectable pulmonary involvement of NHL at diagnosis is about 4%. The commonest intrathoracic manifestations of secondary pulmonary lymphoma are mediastinal or hilar lymph node enlargement. And the most frequent manifestations of pulmonary parenchymal lymphoma are lymphomatous nodules. But, when patients with newly diagnosed lymphoma exhibit rapidly progressive parenchymal lesions, an infection, such as pneumonia, is usually suspected. We present a report of a patient who developed rapidly progressive pulmonary involvement with T cell lymphoma, which was considered to be pneumonia bacause of high fever and rapidly progressive radiologic findings.

This study was aimed to investigate the therapy and prognostic factors of angioimmunoblastic T cell lymphoma (AITL). The clinical data of 23 patients with AITL were collected and the clinical features, laboratorial data, survival and prognostic factor were retrospectively analyzed. The results indicated that the median age of the patients was 62 years. Out of them 21 (91.3%) patients were with intermediate high and high risk according to the international prognostic index (IPI), 14 (60.9%) patients had extranodal disease and 5 (21.7%) patients had autoimmune disease. The overall response rate(ORR) for the whole group was 68.2%, the estimated 3-year and 5-year survival rates were 38.3% and 28.7% respectively. High-dose chemotherapy combined with auto-HSCT improved the outcome of young patients. Immunosuppressive therapy were used in replace/refractory patients. Age more than 65 years, IPI score, LDH level, the number of lymph node involvement, short-term effect, fibrinogen level, β2-MG level and bone marrow involvement were prognostic factors with statistical significance. Cox multivariate analysis showed that the level of LDH, β2-MG and bone marrow involevment were independent prognostic factors, IPI, PIT and mPIT were useful for stratified patients into different prognostic risk groups. It is concluded that AITL is aggressive disease occurred in older patients, and autoimmune dysfunction with infectibility, often appears in AITL patients with poor prognosis. The young patients can be benefited from initial intensive chemotherapy. High-dose chemotherapy combined with auto-HSCT may be a better choice for those patients. Immunosuppressive therapy can be used in replase/refractory patients.

Epstein-Barr virus (human herpesvirus-4) is very common virus that can be detected in more than 95% of the human population. Most people are asymptomatic and live their entire lives in a chronically infected state (IgG positive). However, in some populations, the Epstein-Barr virus (EBV) has been involved in the occurrence of a wide range of B-cell lymphoproliferative disorders (LPDs), including Burkitt lymphoma, classic Hodgkin’s lymphoma, and immune–deficiency associated LPDs (post-transplant and human immunodeficiency virus–associated LPDs). T-cell LPDs have been reported to be associated with EBV with a subset of peripheral T-cell lymphomas, angioimmunoblastic T-cell lymphomas, extranodal nasal natural killer/T-cell lymphomas, and other rare histotypes. This article reviews the current evidence covering EBV-associated LPDs based on the 2016 classification of the World Health Organization. These LPD entities often pose diagnostic challenges, both clinically and pathologically, so it is important to understand their unique pathophysiology for correct diagnoses and optimal management.

A CD7 positive acute leukemia, lacking CD4, CD8, CD3, CD13 and CD33 expression may include 4 categories; acute T-cell leukemia, mixed lineage leukemia, acute undifferentiated leukemia and CD7 positive acute myeloid leukemia. Therefore, the expression of cyCD3 or the presence of TCR gene rearrangement can make the diagnosis of acute T-cell leukemia. We report a patient with acute T-cell lymphoblastic leukemia, showing CD7+, CD4-CD8-, and CD3-expression and TCR gamma gene rearrangement.

BACKGROUND: Recently, the molecular pathologic investigation for clonality in lymphomas has been introduced and has gained a role in the diagnosis of lymphomas. In fact, the clonality test using TCRGR phenomenon has been done by Southern blot analysis (SBA) and polymerase chain reaction (PCR) for molecular pathologic diagnosis of T cell lymphomas. However, it is difficult to perform SBA with paraffin embedded specimens or with samples of small skin biopsies. OBJECTIVE: We investigated the efficacy of PCR amplification of TCR gene in paraffin em-bedded cutaneous T cell lymphomas. METHODS: Iii this study, the clonality was assessed by polymerase chain reaction (PCR) analysis of T cell receptor gamma (TCR) gene from the DNA extracts obtained from paraffin em-bedded tissues (PET) of malignant T cells, B cell lymphomas, and benign cutaneous T cell proliferative disorders. Heteroduple-x-analyses were also performed to rule out the false positives. RESULTS: Among the total of 62 cases analyzed, monoclonality was observed in 4 out of 10 mycosis fungoides, 7 out of 9 cutaneous T cell lymphomas excluding mycosis fungoides, 1 out of 3 angiocentric lymphomas, 2 out of 2 lymphomatosis papulosis, 1 out of 7 large plaque parapsoriasis, and 1 out of 2 T cell lymphomas in other organs. No monoclonality was observed in 9 inflammatory cutaneous diseases, 5 small plaque parapsoriasis, 4 cutaneous B cell lymphomas, and 11 B cell lymphomas in lymph nodes. CONCLUSION: The results suggest that the PCR method and heteroduplex analysis used in this study were not only practical but also efficacious for the diagnosis of cutaneous T cell lymphomas using tissues embedded in paraffins.

OBJECTIVETo explore the value of multiparameter flow cytometry in diagnosis of non-Hodgkin's lymphoma (NHL).

METHODSTwenty patients with NHL admitted in Traditional Chinese Medicine Hospital of Zhengzhou from January 2009 to August 2014 years were enrolled into this study, among them 13 cases received lymnode puncture, 2 cases were given bone marrow aspiration, 2 cases received peripheral blood examination, 3 cases suffered lymphnode biopsy.

RESULTSAfter FCM immune typing and cytological smear, 6 cases was confirmed to be B-SLL, 1 case was B-NHL, 1 case was FL, 5 cases was DLBCL, 2 cases was T-NHL, 3 cases was T-LBL, 1 case was NK/T-NHL, 1 case was PTun.

CONCLUSIONMultiparameter flow cytometry is valuable for diagnosis of non-Hodgkin's of lymphoma.
