A class of non-Hodgkin's lymphoma, which is a type of cancer of the immune system. CTCL is caused by the mutation of T cells where the malignant T cells in the body are pushed to the surface of the skin in a biological process used to rid the body of offending material, causing various lesions to appear on the skin.

(CTCL): A type of non-Hodgkin's lymphoma that first appears on the skin. Also called mycosis fungoides.

Relating to the skin. Ordinarily malignant neoplasms of lymphoid and reticuloendothelial tissues which present as apparently circumscribed solid tumors composed of cells, or histiocytes.

Neoplasms of the T lymphocytes, which effect the skin. Mycosis fungoides, Se'zary syndrome, reticulum cell sarcoma of the skin are all different clinical presentations of CTCL. CTCL is a relatively rare neoplasm. The incidence rises with age and the majority of those affected are between 40 and 60 years old. More common in males than females.

Cutaneous T-cell lymphoma is a disease in which certain cells of the lymph system (called T-lymphocytes) become cancer (malignant) and affect the skin. Lymphocytes are infection-fighting white blood cells that are made in the bone marrow and by other organs of the lymph system. T-cells are special lymphocytes that help the body's immune system kill bacteria and other harmful things in the body.
