A very rare type of non-Hodgkin’s lymphoma that affects the skin. It is a type of cutaneous T cell lymphoma and usually begins with red scaly patches forming on the skin. These can be very itchy. In the second stage raised red plaques (patches) can form. The last stage is raised lumps forming on the skin which are tumours. It is a very slow disease and some people do not progress beyond the first or second stages. It is treated with chemotherapy or steroid creams, radiotherapy and ultraviolet light.
