C84: Mature T/NK-cell lymphomas
C84.9: Mature T/NK-cell lymphoma, unspecified
Mature T/NK-cell lymphoma, unspecified is a type of cancer found in the body's lymph system, which is part of the immune system. This disease occurs when the T-cells or NK (natural killer) cells, which usually help the body fight infections, undergo changes and multiply uncontrollably, forming tumors. The "unspecified" terminology means that the specific subtype of the lymphoma isn't identified. This condition can affect individuals of any age and varies widely in terms of symptoms and disease progression, often depending on the stage at which it is diagnosed. Common symptoms might include swollen lymph nodes, fever, night sweats, unexplained weight loss, and frequent infections among others. It's important to note that mature T/NK-cell lymphoma is a complex condition and the symptoms and progression can vary significantly from patient to patient.
