B-cell lymphomas occurred as transmural lesions in stomach, jejunum, and ileo-cecal-colic junction. The majority were diffuse, large B-cell lymphomas of centroblastic type. In conclusion, T-cell lymphomas characterized by distinctive mucosal architecture, CD3 expression, and clonal expansion predominated in the feline gastrointestinal tract.

Introduction. T-cell large granular lymphocyte (T-LGL) leukemia is a disease characterized by clonal proliferation of cytotoxic T cells (CD8 + cells). The etiology of T-cell LGL leukemia has not been entirely elucidated; however, chronic antigenic stimulation with exogenous antigens such as human T-cell lymphotrophic virus or putative endogenous autoantigens may be responsible for inducing the

CD3 immunostaining shows a marked increase in mature T cells in a case of T-LGL leukemia. The pattern of involvement is typically interstitial/intrasinusoidal and often morphologically occult. LGL leukemia cells have a mature T‐ or NK‐cell immunophenotype [ 3 ]. The most common immunophenotypes for each subtype of LGL leukemia are described in Table 1. CD57 is a 110‐kDa glycoprotein found on NK cells and activated, effector CD8 + T … 2016-07-28 The immunophenotype of the gamma delta T‐cell LGL leukemias differed from that of other gamma delta T‐cell malignancies (Table 3). CD5 expression was common (60% of cases reported here and in the literature) in gamma delta T‐cell LGL leukemias and uncommon in hepatosplenic gamma delta T‐cell lymphomas (13% of cases) and cutaneous gamma delta T‐cell lymphomas (20% of cases). 2006-01-01 2011-01-08 The classic immunophenotype of the malignant T cell in LGL leukemia is CD3 + CD4 − CD8 + CD16 + CD27 − CD45R0 − CD57 + CD94 + [ 8 ].

From www.haematologyetc.co.uk. Features of T-LGL leukaemia. The immunophenotype is that of a mature cytotoxic post-thymic T cell, but with variable aberrant features: CD3and CD8are typically expressed.

Interestingly, in the largest case series of patients diagnosed with T-LGL and a plasma cell disorder by Sidiqi et al., all reported 22 cases, who had T-LGLs, showed the classic immunophenotype (CD8+ positive cells) . Not a single case of CD4/CD8 dual-positive T-LGLL was reported.

T-LGL leukemia is associated with immunological abnormalities: rheumatoid factor with or without rheumatoid arthritis (RA), Coombs positive hemolytic anemia, idiopathic thrombocytopenic purpura (ITP), pure red cell aplasia (PRCA), positive anti-nuclear antibodies (ANA), anti-neutrophil cytoplasmic antibodies (ANCA), hypogammaglobulinemia, and polyclonal hypergammaglobulinemia.

LGL is a clonal lymphoid disorder characterized by cytopenia and clonal expansion of either CD3-positive cytotoxic T lymphocytes or CD3-negative natural killer (NK) cells. Although LGL can be associated with other entities, such as AA or MDS, it is a distinct clinical entity with a specific diagnostic pathway [83,84]. CD4–/CD8– γδ T-LGL leukemia also displays an immunophenotype and pattern of splenic involvement overlapping with hepatosplenic T-cell lymphoma. Clinically, this variant of T-LGL leukemia shows an overall indolent course, but treatment is often required in the initial stages of the disease.

Large granular lymphocyte leukemia (LGL) is a lymphoproliferative disorder, marked by clonal expansion of large granular lymphocytes, usually T cell in origin (85%), with a minority that arise in - T cell LGL leukaemia, consisting of a clonal prolifera - tion of CD3+ LGLs. - Aggressive NK-cell leukaemia, corresponding to an accumulation of NK CD3- LGL cells with an aggressive behaviour. - Chronic lymphoproliferative disorder of NK cells, a chronic and indolent CD3- LGL lymphocytosis.
