Cutaneous T-cell lymphomas (CTCLs) are a group of disorders characterized by an abnormal accumulation of cancerous T-cells (a type of white blood cells) in the skin resulting in an itchy, red rash that can thicken or form a tumor. CTCLs belong to a larger group of disorders known asnon-Hodgkin's lymphomas. The most common types are mycosis fungoides and Sézary syndrome. In some cases, cancerous T-cells may spread to the lymph nodes and eventually to other body tissues and organs, potentially resulting in life-threatening complications. The specific signs and symptoms vary from person to person. The exact cause of these conditions is unknown.[1]
