Signs and symptoms of cutaneous T-cell lymphoma include:  Round patches of skin that may be raised or scaly and might be itchy Patches of skin that appear lighter in color than surrounding skin Lumps that form on the skin and may break open Enlarged lymph nodes Hair loss Thickening of the skin on the palms of the hands and soles of the feet A rash-like skin redness over the entire body that is intensely itchy  Causes The exact cause of cutaneous T-cell lymphoma isn't known. In general, cancer begins when cells develop changes (mutations) in their DNA. A cell's DNA contains instructions that tell a cell what to do. The DNA mutations tell the cells to grow and multiply rapidly, creating many abnormal cells. In cutaneous T-cell lymphoma, the mutations cause too many abnormal T cells that attack the skin. T cells are part of your immune system, and they normally help your body fight germs. Doctors don't know why the cells attack the skin.
