Intralesional and intravenous treatment of cutaneous B-cell lymphomas with the monoclonal anti-CD20 antibody rituximab: report and follow-up of eight cases

Abstract

Rituximab therapy of CBCL appears to have a potential advantage in cases where lesions are localized in sites that are difficult to treat with radiotherapy or surgery and in which secondary scarring or alopecia is likely. Intralesional injections of rituximab allow the use of considerably smaller doses compared with intravenous treatment, with similar response rates and tolerance. However, within a 12-month follow-up period, relapse of CBCL with new lesions at distinct sites was frequently observed after intralesional treatment.
