It is best to read this information with our general information about non-Hodgkin lymphoma (NHL). If you have any more questions, you can ask your doctor or nurse at the hospital where you are having treatment.
Cutaneous means skin. Cutaneous T-cell lymphoma (CTCL) is a type of NHL that affects the skin. It develops when T-cells (also called T-lymphocytes) become abnormal. T-cells are white blood cells that fight infection.
There are different types of CTCL. The most common are called mycosis fungoides and Sézary syndrome.
Mycosis fungoides (MF)
This is the most common type of CTCL. MF is usually a very slow-growing type of lymphoma that often only affects the skin.
For most people, MF will develop slowly or stay under control for many years. In a small number of people, MF may spread to other parts of the body over time.
In this type of CTCL, the abnormal T-cells affect the skin but are also found in other areas of the body such as the blood and lymph nodes. Lymph nodes are part of the body’s lymphatic system. They filter out disease and germs (bacteria and viruses) as fluid passes through them.
