C82.5: Diffuse follicle centre lymphoma

Diffuse follicle center lymphoma, coded as C82.5 in the ICD-10, is a type of non-Hodgkin lymphoma, which is a cancer that begins in cells of the body's immune system. This condition specifically starts in the center of the lymph follicles, which are parts of the lymph nodes. The term "diffuse" refers to the way the cancer cells have spread out or infiltrated in an unorganized way within the lymph node. Symptoms of this condition often include painless swelling of the lymph nodes in the neck, armpits, or groin. Other symptoms can be fatigue, fever, night sweats, and unexplained weight loss. The disease progression is typically slow, and many affected individuals live many years after diagnosis. It can, however, disrupt the immune system’s ability to fight infections.
