What is cutaneous lymphoma?
Cutaneous lymphoma (also called lymphoma of the skin) is a rare type of non-Hodgkin lymphoma that affects the skin. There are approximately 72,580 cases of NHL diagnosed each year, only 5 percent of which are skin lymphomas, according to the American Cancer Society.
Cutaneous lymphomas result in rashes, and sometimes tumors, which can be mistaken for other skin conditions. In a small number of people the disease may migrate to the lymph nodes or internal organs, causing serious complications. Skin lymphomas are rarer and behave very differently than systemic lymphomas, and usually require different treatments.
There are several subtypes of skin lymphoma that are based on the type of cell in which the disease starts, including:
- T-cell lymphoma
- B-cell lymphoma
- NK-cell lymphoma
Among skin lymphomas, T-cell lymphomas are the most commonly diagnosed.
