متن کاملT - Cell - Rich B - Cell Lymphoma
We analyzed 23 cases of T-cell-rich B-cell lymphomas (BCL) to determine if the clinical features are characteristic of a discrete entity. Cases encoded as T-cell-rich BCL in the hematopathology archives of the University of Texas M.D. Anderson Cancer Center between 1988 and 1991 formed the basis of this study. At least 50% of the total population of cells were required to be of T-cell phenotype...
متن کاملT-cell rich B-cell lymphoma.
Five cases of B-cell lymphoma are described in which the morphology and initial immunohistochemistry suggested a diagnosis of T-cell neoplasia. In four cases, the histological picture was that of an adult pleomorphic T-cell lymphoma; the fifth case was a lymphocytic lymphoma (CLL) with an accompanying T-cell lymphocytosis in the peripheral blood. Immunohistochemistry on both frozen and paraffin...
متن کاملIntravascular Large B-cell Lymphoma: A Report of Two Cases
One of the rare variants of extranodal large B-cell lymphoma is intravascular large B-cell lymphoma (IVLBCL). Characteristics of IVLBCL include intraluminal selective proliferation of atypical lymphoid cells in small to medium-sized vessels. The etiologic of IVLBCL is unknown, but due to the growth pattern of this tumor, it is speculated that IVLBCL is caused by a defect in homing receptor of t...
