A relatively uncommon form of cancer, cutaneous T-cell lymphoma affects certain white blood cells (T cells). A key component of the body’s immune system, T cells develop from stem cells in the bone marrow and are found in lymphatic tissues found throughout the body, such as in the tonsils, spleen, intestines and skin. These infection-fighting cells fend off disease by targeting and destroying harmful invaders, such as bacteria and viruses.
Cutaneous T-cell lymphoma occurs when T cells undergo mutations that cause them to grow and divide uncontrollably. The resulting abnormal T cells then build up and attack the skin, producing rash-like skin redness, slightly raised or scaly round skin patches and, in some cases, skin tumors. The malignancy is classified as a type of non-Hodgkin’s lymphoma.
What prompts abnormal cellular DNA changes?
Although research is ongoing, scientists in the general medical community have not yet determined why some T cells mutate or why the mutated T cells inadvertently attack the skin. Based on extensive studies, some experts believe that contributing factors may include:
- Genetic and immunologic abnormalities
- Environmental factors, such as exposure to ultraviolet (UV) light, certain chemicals or ionizing radiation
- Certain viral infections and bacterial skin infections
- Lifestyle factors, such as poor nutrition or stress
As such, the abnormal genetic changes that lead to the development of cutaneous T-cell lymphoma may be inherited or they may occur spontaneously for reasons that are not yet well understood.
