Simultaneous pectoralis major muscle and orbital metastasis as the primary presentation of pulmonary adenocarcinoma.

A 63-year old male with chronic shoulder pain and painful left eye with binocular diplopia of sudden onset was seen independently by Ophthalmologists and his family Doctor and investigated first non-invasively where masses were found both in the orbit and pectoralis muscle. Further investigations including biopsy confirmed non-small cell lung carcinoma with metastasis to these sites; unusual sites of tumour metastasis and the first reporting of such tumour behaviour.
