unspecified peripheral T-cell lymphoma
Peripheral T-cell Lymphoma Not Otherwise Specified(PTCL NOS) refers to a group of diseases that do not fit into any of the other subtypes of PTCL. PTCL-NOS is the most common PTCL subtype, making up about one quarter of all PTCLs. It is also the most common of all the T-cell lymphomas. The term PTCL can be confusing as it can refer to the entire spectrum of mature T-cell lymphomas, but it can also refer to the specific PTCL-NOS subtype. Although most patients with PTCL-NOS are diagnosed with their disease confined to the lymph nodes, sites outside the lymph nodes, such as the liver, bone marrow, gastrointestinal tract, and skin, may also be involved. This group of PTCLs is aggressive and requires combination chemotherapy upon diagnosis.
