2005年血液病理学会/欧洲血液病理协会第11次研讨会专门讨论肝脾t细胞淋巴瘤(HSTCL)。HSTCL是一种罕见的侵袭性结外淋巴瘤,以肝脾肿大、骨髓受累和外周血细胞减少为特征。HSTCL表现出独特的浸润模式;肿瘤细胞优先浸润脾红髓、肝和骨髓的窦状体。肿瘤细胞具有非活化的细胞毒性t细胞免疫表型,经常携带复发性细胞遗传学异常,同染色体7q。大多数病例表达γΔ t细胞受体,但病例可能具有αβ表型,被认为是该疾病的一种变体。虽然HSTCL是表达γΔ T细胞受体的原型外周T细胞淋巴瘤,但γΔ T细胞的非HSTCL增殖可累及其他结外部位,主要是皮肤和粘膜。这些γΔ t细胞淋巴瘤在临床和组织学特征上表现出明显的异质性。与HSTCL相比,非HSTCL γΔ t细胞淋巴瘤通常具有活化的细胞毒性表型,并且很可能不是单一的疾病实体。
The 2005 Society for Hematopathology/European Association for Haematopathology Workshop session 11 was dedicated to hepatosplenic T-cell lymphoma (HSTCL). HSTCL is a rare aggressive type of extranodal lymphoma characterized by hepatosplenomegaly, bone marrow involvement, and peripheral blood cytopenias. HSTCL exhibits a distinctive pattern of infiltration; tumor cells preferentially infiltrate the sinusoids of the splenic red pulp, liver, and bone marrow. The tumor cells have a nonactivated cytotoxic T-cell immunophenotype and frequently carry a recurrent cytogenetic abnormality, isochromosome 7q. Most cases express the γΔ T-cell receptor, but cases can have an αβ phenotype and are considered to be a variant of the disease. Although HSTCL is the prototype peripheral T-cell lymphoma expressing the γΔ T-cell receptor, non-HSTCL proliferations of γΔ T cells can involve other extranodal sites, mainly skin and mucosa. These γΔ T-cell lymphomas display marked heterogeneity in clinical and histologic features. In contrast with HSTCL, non-HSTCL γΔ T-cell lymphomas frequently have an activated cytotoxic phenotype and most likely are not a single disease entity.
