title: 'Proptosis'--may be the only presenting feature of small cell lung cancer: a case report.
abstract: Orbital metastasis from solid tumours is an uncommon entity and lung, breast and nasopharyngeal cancers are the common sites causing such a metastasis. Proptosis as the only presenting feature without any symptom suggesting lung as the primary site is very rare. Here is a report of a patient who presented with proptosis as the only complaint and subsequent investigations proved it to be due to small cell lung cancer metastasis and without metastatic spread to any other site.
