Cutaneous B-cell lymphoma is a rare type of cancer that begins in the white blood cells. This cancer attacks the skin. Cutaneous B-cell lymphoma affects one type of germ-fighting white blood cells called B cells. These cells also are called B lymphocytes.
The types of cutaneous B-cell lymphoma include:
- Primary cutaneous follicle center lymphoma.
- Primary cutaneous marginal zone B-cell lymphoma.
- Primary cutaneous diffuse large B-cell lymphoma, leg type.
- Intravascular diffuse large B-cell lymphoma.
Cutaneous B-cell lymphoma symptoms include a lump or group of lumps on the skin. Sometimes this cancer causes hard patches of skin.
Cutaneous B-cell lymphoma is a type of non-Hodgkin lymphoma. Another type of non-Hodgkin lymphoma that affects the skin is called cutaneous T-cell lymphoma. Cutaneous T-cell lymphoma is more common than cutaneous B-cell lymphoma.
