Cutaneous Lymphomas

Cutaneous lymphoma, also called skin lymphoma, is a rare type of non-Hodgkin lymphoma that affects the skin. It is a cancer of the lymphocytes (white blood cells), and there are two sub-types: B-lymphocyte (B-cell) cutaneous lymphoma and T-lymphocytes (T-cell) cutaneous lymphoma. Cutaneous lymphoma is sometimes incorrectly called a skin cancer because it is a cancer and it affects the skin. However, “skin cancer” refers to cancers that develop from skin cells (epidermal cells or melanocytes), and cutaneous lymphoma actually develops from blood cells.


Eczema, or atopic dermatitis, is an allergic condition that causes inflammation of the skin. It can be triggered by just about anything coming in contact with the skin. It occurs most commonly in people who have sensitive skin.


Melanoma is a type of skin cancer that begins in melanocytes – the cells that produce the pigment melanin that colors the skin, hair and eyes. Melanocytes also form moles, where melanoma often develops. Melanoma is the most dangerous form of skin cancer. Melanoma is usually the result of DNA damage caused by ultraviolet radiation from sunshine or tanning beds, but genetic defects also can trigger melanoma to develop.


Psoriasis is a common skin condition that causes raised, red scaly patches to appear on the skin. The patches occur because the skin cells multiply much faster than normal. Psoriasis typically occurs on the knees, elbows and scalp but can also be found on the torso, palms and soles of the feet.

Urticaria (Hives)

Urticaria, also called hives or angiodema, affects up to 25 percent of people at some point in their lives.
