title: Treatment of localized oral MALT lymphoma by rituximab: a case report.
abstract: BACKGROUND
  Extranodal marginal zone B cell lymphoma of mucosa-associated lymphoma tissue (MALT) among intraoral malignant lymphomas is very rare. Moreover, no case of oral MALT lymphoma treated with monoclonal antibody therapy has been reported.
  
  
  CONCLUSIONS
  We describe a case of MALT lymphoma arising in an 87-year-old Japanese woman under the buccal mucosa that was successfully treated with rituximab, a chimeric monoclonal antibody against the B cell-specific antigen CD20. Currently, 5 months after completing treatment, the patient is alive and has partial regression of the tumor.
