We report a case of CD7+ stem cell lymphoma. A 47-year-old man presented with general malaise and lumbago in April 1997. The patient exhibited swollen left cervical lymph-nodes and an intra-abdominal bulky mass. He was referred to us because lymph-node biopsy specimens indicated a diagnosis of diffuse type malignant lymphoma. An abdominal CT scan disclosed large retroperitoneal, para-aortic, and mesenteric root masses. Bone marrow involvement was shown by bone marrow biopsy specimens, though no circulating blasts were detected at presentation. The patient was treated with high-dose CHOP therapy without any benefit. Though ESHAP therapy was performed as salvage chemotherapy, the abdominal masses did not shrink at all. The patient died of tumor progression in November 1997. In the terminal stage, the lymphoma cells emerged in the peripheral blood and thus became available for analysis. The cells expressed CD5, 7, 34, 38, 71, but were negative for CD1, 2, 3, 4, 8, 10, 13, 14, 16, 19, 20, 21, 25, HLA-DR, and EMA. An immunoglobulin heavy chain gene rearrangement band was detected by Southern blot analysis. However, no T cell receptor lambda or beta chain gene rearrangement bands were detected.

We report the case of a 77-year-old Japanese man with natural killer (NK)-like T cell lymphoma of the small intestine diagnosed after an emergency laparotomy for perforated peritonitis. Immunohistochemical staining of the tumor showed that the patient had CD3+ CD8+ CD30- CD56+ CD68- CD79a- UCHL-1+ EMA- LMP-1 NK-like T cell lymphoma. The patient had a history of hepatocellular carcinoma (HCC) and was also diagnosed with T cell non-Hodgkin's lymphoma associated with T cell receptor (TCR) reconstruction in the Jgamma chain. Intestinal T cell lymphoma is uncommon and very few cases of CD56+ T cell lymphoma, otherwise known as NK-like T cell lymphoma, have been reported. The patient did not have a history of gluten-sensitive enteropathy (celiac disease). Multiple lesions appeared within months after the initial operation and his condition deteriorated rapidly. We think that this patient probably had NK-type granular lymphocyte-proliferative disorder (NK-GLPD) because the percentage of CD16+ CD56+ cells among peripheral blood mononuclear cells was elevated, at 21%. We report this case to help elucidate the relationship between underlying digestive organ disease and the development of intestinal NK-like T cell lymphoma. An accumulation of other such cases is needed to determine the etiology of this disease.

Targeting the pathogenic pathway of chronic inflammation represents an unmet challenge for controlling disease activity, preventing functional disability, and maintaining an adequate quality of life in patients with rheumatic diseases. Abatacept, a novel molecule that inhibits co-stimulation signal, induces an inhibitory effect on the T-cells. This will further interfere with the activity of several cell lines, leading to the normalization of the immune response. In the latest years, abatacept has been extensively investigated in studies of rheumatoid arthritis for which it was recently approved as a second line biologic treatment in Romania. This review presents the clinical efficacy of abatacept in several rheumatic diseases and highlights the safety profile of this biological agent.
