We report a case of CD3‐negative, CD20‐positive T‐cell prolymphocytic leukemia (T‐PLL). The leukemic cells were of medium‐to‐large size, mature‐looking, and did not have cytoplasmic granules. The leukemic cells were negative for surface CD3, CD2, and CD7 and strongly positive for CD20. T‐cell lineage markers such as CD4, CD5, and cytoplasmic CD3 were also positive. A monoclonal rearrangement of the T‐cell receptor (TCR) β chain gene was detected. CD3‐negative T‐PLL has been reported often, but… 
CD20-positive T-cell large granular lymphocyte leukemia: case report and review of the literature.
TLDR
Additional cases must be evaluated to clarify the implications of CD20 expression on T-cell malignancies and to elucidate whether such cases constitute a distinct biologic and clinical disease entity.
CD20- and CD56-Positive T-Cell Large Granular Lymphocyte Leukemia in a Human T-Cell Leukemia Virus Type 1 Carrier
TLDR
Phenotypically, neoplastic cells of the 60-year-old man diagnosed with asymptomatic T-cell granular lymphocyte (T-LGL) leukemia were CD3+, CD4, CD8, CD16, CD56, CD57, and T- cell receptor (TCR) αβ+.
Clinicopathologic Features of B-Cell Lineage Neoplasms With Aberrant Expression of CD3: A Study of 21 Cases
TLDR
The spectrum of morphologic, phenotypic, and clinical features of B-cell neoplasms aberrantly expressing CD3 are expanded, and DLBCLs with anaplastic features and the single follicular lymphoma coexpressed multiple T-cell antigens in a predominantly membranous pattern and presented with nodal disease in a relatively younger patient population.
CD20-positive NK/T-cell lymphoma with indolent clinical course: report of case and review of literature
TLDR
The accurate diagnosis of NK/T-cell lymphoma with CD20 expression in nasal cavity occurring in an elder female patient is important, but the indolent behavior of the present case is more unusual.
CD20+ T-cell Lymphoma: Clinicopathologic Analysis of 9 Cases and a Review of the Literature
TLDR
Knowledge of the unusual phenomenon of CD20 expression in TCL, in conjunction with careful morphologic analysis, the use of a panel of antibodies, and molecular genetic studies, is important in avoiding a misdiagnosis of BCL.
TCL1A gene involvement in T-cell prolymphocytic leukemia in Japanese patients
TLDR
Expression and/or rearrangement of TCL1A may, therefore, be a useful marker for diagnosing T-PLL, regardless of chromosomal abnormalities.
CD20‐positive extranodal NK‐cell lymphoma, nasal‐type
TLDR
Flow cytometric, immunohistochemical and Southern blot analysis have definitely concluded that the present case is a typical extranodal NK-cell lymphoma, nasal type and treatment with rituximab failed, and the patient died of the disease progression after six months.
CD20+ Mycosis Fungoides: A Report of Three Cases and Review of the Literature
TLDR
Phenotypically, the aberrant cell populace demonstrated a CD4+, CD7−, and CD62L− phenotype; at variance with classic MF was the expression of CD20, and although there were a few PAX5-positive staining cells, definitive colocalization studies were negative.
T-cell prolymphocytic leukemia in Japan: is it a variant?
TLDR
It is proposed that Japanese cases of T-PLL may constitute a variant, based on clinical and biological features of 13 cases diagnosed between 1992 and 2009 in the Tohoku region of Japan, which were compared with three Western series.
RAPID PROGRESSION OF CLAVICULAR SOLITARY PLASMACYTOMA TO MULTIPLE MYELOMA
TLDR
Early detection of systemic symptoms is very important in the management of solitary plasmacytoma and high proliferation index (Ki67>8%) and tumor size (>5cm) were the risk factors for rapid progression of plasmatetoma.

CD20‐positive T‐cell chronic lymphocytic leukaemia
TLDR
This is the first report of a case of clonal expansion of CD20dim Tlymphocytes in a man developed pancytopenia and hepatosplenomegaly due to clonal proliferation of atypical lymphocytes that were weakly positive for CD20.
CD20‐positive adult T‐cell leukemia
TLDR
This is the first report of CD20‐positive ATL, suggesting that HTLV‐I can infect and transform CD20-positive T cells, and a novel T‐cell subpopulation expressing CD20 molecules has recently been identified.
Large granular lymphocytic leukaemia with a mixed T‐cell/B‐cell phenotype
TLDR
The expression of both T‐ and B‐cell markers on the LGLL cells suggests the involvement of a putative common lymphoid progenitor in leukaemic transformation.

TLDR
T-PLL is a distinct T-cell disorder with characteristic clinical and laboratory features and a poor prognosis and a precise diagnosis of this disease is important in determining patient management and treatment.
Clinical and laboratory features of 78 cases of T-prolymphocytic leukemia.
TLDR
The clinical course was progressive with a median survival of 7.5 months and the response rate increased to 58% in patients with a CD4+ CD8- phenotype, and a subgroup of patients may benefit from deoxycoformycin.
Low level CD20 expression on T cell malignancies.
TLDR
Low ABC CD20 expression by T lymphocytic malignancies may provide a more unique immunophenotypic "fingerprint" to help support the diagnosis of T cell neoplasia vs. normal/reactive T cells and facilitate monitoring patients for residual or recurrent disease.
FMC7 antigen expression on normal and malignant B-cells can be predicted by expression of CD20.
TLDR
It is concluded that little additional information is revealed by using FMC7 in immunophenotyping of non-Hodgkin's lymphomas or chronic lymphoid leukemias if intensity of CD20 expression is taken into consideration.
Early stages in the development of human T, natural killer and thymic dendritic cells
TLDR
T‐cell development is initiated when CD34+ pluripotent stem cells or their immediate progeny leave the bone marrow Co and migrate to the thymus, where they develop into T, natural killer and dendritic cells.
True T-cell chronic lymphocytic leukemia: a morphologic and immunophenotypic study of 25 cases.
TLDR
T-CLL is an uncommon chronic lymphoproliferative disorder (CLPD) that can be morphologically similar to B-C LL, is distinct from T-prolymphocytic leukemia, and has an aggressive clinical course that is refractory to therapy.
Transient Expression of CD20 Antigen (Pan B Cell Marker) in Activated Lymph Node T Cells
TLDR
It is suggested that lymphocyte activation in the LNs induced expression of the CD20 molecule in some T cells in monkey lymph node (LN) T cells.
