Renal cell carcinoma metastasis masquerading as recurrent orbital haematoma.

ABSTRACT

A 70 year old man developed orbital haemorrhage after retrobulbar anaesthesia for cataract surgery and biopsy of a persistent lateral rectus mass suggested organising haematoma. Subsequent progression of the mass was shown, on repeated biopsy, to be due to metastatic renal cell carcinoma--a tumour recognised for its angiogenic and haemorrhagic potential.
