title: Multifocal extranodal lymphoma: A case report.
abstract: BACKGROUND
  We report an unusual and interesting case of non-Hodgkin lymphoma involving 7 extranodal sites.In this case, a 43-year-old woman with diffuse large B-cell lymphoma, including stomach, breasts, pancreas, adrenal glands, ovary and bones, was confirmed by biopsy and positron emission tomography/computed tomography scan. The patient achieved a complete response after 2 cycles of chemotherapy with combined rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone, but subsequently developed central nervous system involvement.
  
  
  CONCLUSIONS
  This case illustrated the usefulness of positron emission tomography/computed tomography in diagnosis, disease staging, and assessment of response to therapy. Selection of the optimal treatment regimen is challenging and needs further research.
