title: Midline granuloma presenting as orbital cellulitis.
abstract: BACKGROUND
  Lethal midline granuloma usually presents with rhinorrhoea and redness of the skin above the nose. Early ocular symptoms are very rare. We here describe a patient who presented with acute orbital cellulitis.
  
  
  METHODS
  A 73-year-old woman had a 24-h history of severe pain around her left eye. We saw the typical clinical picture of orbital cellulitis. A CT scan revealed a diffuse infiltration of the left upper and lower lid, the anterior orbit and the ethmoidal sinuses.
  
  
  RESULTS
  On surgical exploration we found a granular, partly necrotic tumour. Histological examination revealed an angiocentric nasal T-cell lymphoma (midline granuloma).
  
  
  CONCLUSIONS
  Midline granuloma should be included in the differential diagnosis of acute orbital cellulitis.
