T-cell lymphoma describes several different types of Non-Hodgkin lymphoma affecting T cells or Natural killer cells (NK-cells), also known as a NK/T-cell lymphoma. Any organ that has lymphatic tissue may develop a lymphoma, including the spleen, thymus, adenoids, tonsils, digestive tract and bone marrow. Characteristically, they may present as fast (aggressive) or slow (indolent) growing lymphomas.
Lymphomas are named after the precursor cell from which it developed. A peripheral T-cell lymphomas include lymphomas which arise from mature T-cells (after maturation in the thymus), in contrast with immature T-cell lymphomas, the lymphoblastic lymphoma.
T-cell lymphomas may be classified according to updated WHO classification into 2 subtypes:
|T-cell and putative NK-cell neoplasms|
|Precursor T-cell neoplasm|
|Precursor T-acute lymphoblastic leukemia / lymphoblastic lymphoma (LBL)|
|Peripheral T-cell and NK-cell neoplasms|
|T-cell prolymphocytic leukemia|
|T-cell granular lymphocytic leukemia|
|Chronic lymphoproliferative disorder of NK cells|
|Aggressive NK-cell leukemia|
|Systemic EBV positive T-cell lymphoma of childhood|
|Hydroa vacciniforme like lymphoproliferative disorder|
|Adult T-cell leukemia/lymphoma|
|Extranodal T/NK-cell lymphoma, nasal type|
|Enteropathy associated intestinal T-cell lymphoma|
|Monomorphic epitheliotropic intestinal T-cell lymphoma|
|Indolent T-cell lymphoproliferative disorder of the GI tract|
|Hepatosplenic T-cell lymphoma|
|Subcutaneous panniculitis-like T-cell lymphoma|
|Primary cutaneous CD30 T-cell lymphoproliferative disorders
|Primary cutaneous gamma delta T-cell lymphoma
Primary cutaneous CD8 aggressive epidermotropic cytotoxic T-cell lymphoma
Primary cutaneous acral CD8 T-cell lymphoma
Primary cutaneous CD4 small/medium T-cell lymphoproliferative disorder
|Peripheral T-cell lymphoma, NOS *
Peripheral T-cell lymphoma, not otherwise characterized
|Angioimmunoblastic T-cell lymphoma|
|Follicular T-cell lymphoma|
|Nodal peripheral T-cell lymphoma with TFH phenotype|
|Anaplastic large cell lymphoma
|Breast implant associated anaplastic large-cell lymphoma|
