Susan Thornton, CEO of Cutaneous Lymphoma Foundation, gives an overview of cutaneous lymphoma and its subtypes.

Cutaneous lymphoma is a rare subtype of non-Hodgkin lymphoma that primarily affects the skin. Cutaneous lymphoma can originate in B-cells (i.e., cutaneous B-cell lymphoma; CBCL); however cutaneous T-cell lymphoma (CTCL) is more common. 

There are many forms of (CTCL) but mycosis fungoides and Sézary syndrome are the most common and most severe. As Ms. Thornton explains, mycosis fungoides often presents first with a rash which may or may not be itchy which is why it is often misdiagnosed. Sézary syndrome is less common than mycosis fungoides but easier to diagnose as Sézary syndrome often presents with red, unbearably itchy skin all over the body.
