What is cutaneous B-cell lymphoma?

Cutaneous B-cell lymphoma (CBCL) is a rare type of cancer that starts in your skin. It’s a form of “extranodal” (outside of your lymph nodes) lymphoma.

Most cases look like a rash or lump(s) on your skin. They usually grow slowly and rarely spread or affect other parts of your body.

CBCL is also called B-cell skin lymphoma.
