title: Orbital T-cell lymphoma in a multiple myeloma patient.
abstract: OBJECTIVE
  To report an 82-year-old woman with multiple myeloma who developed an orbital T-cell lymphoma concomitantly.
  
  
  METHODS
  The patient presented with left upper eyelid swelling. Magnetic resonance imaging demonstrated an orbital mass compressing the eyeball. The mass was excised for diagnostic purposes and orbital decompression.
  
  
  RESULTS
  Histopathologic and immunohistochemical evaluation identified the mass as a T-cell lymphoma. The disease progressed rapidly despite chemotherapy.
  
  
  CONCLUSIONS
  Orbital T-cell lymphoma is rare and we are unaware of previous reports of orbital T-cell lymphoma in patients with multiple myeloma.
