Peripheral T-cell lymphoma

Peripheral T-cell lymphoma (PTCL) represents a biologically heterogeneous group of aggressive non-Hodgkin lymphomas arising from mature, post-thymic T lymphocytes or natural killer (NK) cells

Peripheral T-cell lymphoma (PTCL) represents a biologically heterogeneous group of aggressive non-Hodgkin lymphomas arising from mature, post-thymic T lymphocytes or natural killer (NK) cells Clinically, these malignancies often follow a rapid, invasively progressive course with high relapse rates and historically poor long-term outcomes compared to their B-cell counterparts

The condition primarily impacts the lymphatic and immune systems, typically presenting in older adults with widespread lymphadenopathy, frequent extranodal organ involvement (such as the liver, spleen, bone marrow, and skin), and systemic B symptoms

Pathophysiologically, PTCL is characterized by clonal expansion driven by recurrent genetic and epigenetic alterations, dysregulation of T-cell receptor signaling pathways, and profound remodeling of the tumor microenvironment
