title: Orbital involvement by non-Hodgkin lymphoma NK T cells.
abstract: METHODS
  The case is presented of 37 year-old male with a history of nasal obstruction with right rhinorrhea, headache, hearing loss and right exophthalmos of 4 months progression. The MRI revealed that the ethmoidal and maxillary sinuses contained inflammatory tissue extending into the orbital region. The biopsy confirmed a non-Hodgkin lymphoma of natural killer (NK) T cells.
  
  
  CONCLUSIONS
  Non-Hodgkin's T NK lymphoma is a rare tumor in the orbital area that requires an early detection and multi-disciplinary care to ensure appropriate monitoring and treatment.
