C82: Follicular lymphoma

C82.6: Cutaneous follicle centre lymphoma

Cutaneous follicle center lymphoma is a type of non-Hodgkin's lymphoma, a cancer that originates in the lymphatic system - the body's disease-fighting network. Specifically, this condition involves the follicle centre cells, which are a type of white blood cell called B lymphocytes or B cells. The term "cutaneous" indicates that this lymphoma affects the skin. Unfortunately, the exact cause of cutaneous follicular center lymphoma is unknown. It starts when healthy B cells develop errors in their DNA. These errors make cells grow and divide out of control, therefore, forming a mass of abnormal cells, which is a tumor. The disease often affects the skin with symptoms including red or purple lumps or patches on the skin that might be itchy. Progression is usually slow, and the disease can remain stable for many years. Nevertheless, medical consultation is required, since any change can indicate disease progression.
