title: Intraocular lymphoma metastasis from larynx.
abstract: OBJECTIVE
  To present a rare case of primary larynx diffuse large B cell lymphoma non-Hodgkin's lymphoma (NHL), disseminated to the cerebellum and the intraocular tissue.
  
  
  METHODS
  A 69-year-old man noticed blurred vision in both eyes. The vitreous contained infiltrating cells bilaterally, and floating opacities were increased. We performed vitrectomy to recover the vision and diagnose for both eyes.
  
  
  RESULTS
  The authors discovered diffuse large B cell NHL with cytopathologic examination from vitreous specimen in this case, which was identical with diffuse large B cell NHL of the larynx and cerebellum, and therefore could diagnose the intraocular lesion as the metastasis of NHL. Although the vision improved, the patient had remarkable visual disturbance in both eyes at 6 months after surgery because of the chorioretinal lesion. The authors treated by the combined curative chemotherapy and radiotherapy to ocular tissue, since providing sufficient evidence that the chorioretinal lesion was to predict the metastasis of diffuse large B cell NHL After those treatments, chorioretinal lesions have disappeared in both eyes and the vision has recovered.
  
  
  CONCLUSIONS
  Increased attention to the possibility of dissemination of laryngeal NHL to the intraocular tissue is needed.
