Final diagnosis Peripheral T-cell lymphoma with CNS metastasis Peripheral T-cell lymphoma with CNS metastasis

Peripheral T Cell Lymphoma They represent 7% of all cases of non-Hodgkin's lymphoma. They represent 7% of all cases of non-Hodgkin's lymphoma. T-cell prolymphocytic leukemia  a high white blood cell count, usually characteristic prolymphocytic morphology, and expression of surface CD3 with either CD4 or CD4 and CD8 T-cell prolymphocytic leukemia  a high white blood cell count, usually characteristic prolymphocytic morphology, and expression of surface CD3 with either CD4 or CD4 and CD8 T-cell large granular lymphocytic leukemia  most often CD3, CD8, CD57, and TIA-1 expression. T-cell large granular lymphocytic leukemia  most often CD3, CD8, CD57, and TIA-1 expression. aggressive NK-cell leukemias, and aggressive NK-cell leukemias, and adult T-cell lymphoma/leukemia.. adult T-cell lymphoma/leukemia..

Clinical Characteristics Median Age, years : 61 y/o Median Age, years : 61 y/o B Symptoms, % : 50% B Symptoms, % : 50% Bone Marrow Involvement, % : 36% Bone Marrow Involvement, % : 36% Gastrointestinal Tract Involvement, % : 15% Gastrointestinal Tract Involvement, % : 15% % Surviving 5 years : 25% % Surviving 5 years : 25%

Diagnosis Mostly CD4+, but a few will be CD8+, both CD4+ and CD8+, or have an NK cell immunophenotype. Mostly CD4+, but a few will be CD8+, both CD4+ and CD8+, or have an NK cell immunophenotype. No characteristic genetic abnormalities have yet been identified, but translocations involving the T cell antigen receptor genes on chromosomes 7 or 14 may be detected. No characteristic genetic abnormalities have yet been identified, but translocations involving the T cell antigen receptor genes on chromosomes 7 or 14 may be detected. human T-cell lymphoma/leukemia viruses I and II (HTLV-I and HTLV-II), Epstein-Barr virus (EBV), and human herpesvirus 8 (HHV- 8) sequences as previously described. human T-cell lymphoma/leukemia viruses I and II (HTLV-I and HTLV-II), Epstein-Barr virus (EBV), and human herpesvirus 8 (HHV- 8) sequences as previously described. The neoplastic nature of a T-cell infiltrate is established by histologic features in combination with failure to determine an inflammatory cause and demonstration of monoclonality of T-cell receptor genes.

Immunohistochemistry Indirect biotin-avidin method --detect the antigens. Indirect biotin-avidin method --detect the antigens. Monoclonal antibodies used in the tests were for detecting CD20, CD30, and anaplastic lymphoma kinase (ALK) ; CD3, CD4, CD8, CD56, CD57, Ki-67, granzyme B, pancytokeratin, and glial fibrillary acidic protein and TiA-1.

Treatment Treatment regimens are the same as those used for diffuse large B cell lymphoma, but patients with peripheral T cell lymphoma have a poorer response to treatment.
