Its symptoms vary. Often it is confined to the skin and can be treated and cured.
Aggressive forms can extend beyond the skin to the lymph nodes, blood, and internal organs.
Cutaneous T cell lymphoma is frequently referred to as mycosis fungoides. In this chronic disorder, malignant T cells migrate to, and multiply in, the skin. Left untreated, these malignant cells may remain in the skin for years and sometimes for decades. They eventually spread to the lymph nodes, blood, or internal organs. Treatment, especially in early stages, can result in cure.
