Cutaneous T-Cell Lymphoma
Cutaneous T cell lymphoma (CTCL) is a rare type of cancer that affects the skin, blood and occasionally, lymph nodes and internal organs. It occurs when a type of cell called a T lymphocyte grows out of control. Patients with mild cases may have only a rash. In more severe cases, tumors can form.
The cause of CTCL is not known, and only 5 to 10 people per million people are affected. It is more common in men than women and after age 50.
