title: [Acute proptosis as first symptom of a lung carcinoma].
abstract: OBJECTIVE
  We present the case of a 57-year-old patient who was visited in our ophthalmology department complaining of acute right ocular proptosis, fever and malaise. The clinical, ophthalmic and radiologic examination showed the presence of an extraconal orbital tumor as the cause of this exophthalmos.
  
  
  CONCLUSIONS
  Further complementary studies revealed a small cell carcinoma of the lung metastatic to the right orbit. We report the excellent response to chemotherapy both of the primary lung neoplasm and the orbital metastasis.
