title: CD20-negative relapse of cutaneous B-cell lymphoma after anti-CD20 monoclonal antibody therapy.
abstract: Despite cutaneous B-cell lymphoma often having a relatively indolent course and low mortality, it is often resistant to conventional therapy and frequently relapses. We describe a patient with widespread cutaneous B-cell lymphoma who was treated successfully with a recently approved chimeric monoclonal antibody directed against the CD20 antigen (rituximab) and the CD20-negative relapse that resulted.
