Overview

Cutaneous B-cell lymphoma is a rare type of cancer that begins in the white blood cells and attacks the skin. Cutaneous B-cell lymphoma begins in the B cells — one type of disease-fighting white blood cells called 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 may form as a nodule under the skin that may be the same color as your skin or may appear pink or purple.
