Cutaneous (skin) lymphomas are cancers of lymphocytes (a type of white blood cells) that primarily involve the skin. Cutaneous T-cell Lymphoma (CTCL) is the most common type of cutaneous lymphoma, and typically presents with red, scaly patches or plaques on the skin. Itching can occur; however, less than 80% of people with CTCL reporting they have itch. CTCL often mimics eczema, psoriasis, or other chronic dermatitis, and because of this, it’s common that the diagnosis of CTCL is delayed, sometimes by years or decades. See Cutaneous T-cell Lymphoma for signs, symptoms and treatments.
