Treatment of primary cutaneous B-cell lymphoma with rituximab

Rituximab is a genetically engineered antibody directed against the CD20 antigen. Intravenous administration of rituximab has been used for the treatment of patients with low-, intermediate-, and high-grade B-cell non-Hodgkin's lymphomas and is a registered treatment modality for this indication. Treatment of primary cutaneous B-cell lymphoma (CBCL) with intralesionally or systemically administered rituximab has been described only in a few cases.
