Retinal infiltrates secondary to metastatic squamous cell carcinoma masquerading as infectious retinitis.
OBJECTIVE
This report presents a case of metastatic carcinoma to the retina.


METHODS
Retrospective chart review and systematic literature review. The patient was a 78-year-old man with history of small-cell lung cancer and with the development of metastatic carcinoma to the retina.


RESULTS
The review of this case and previous literature reveals that the presentation of retinal metastases can occasionally be misinterpreted as infectious retinitis, which can delay the diagnosis of the disease.


CONCLUSIONS
Metastatic carcinoma to the retina is a rare condition, which should be considered in patients who are suspected of having infectious retinopathy and who fail to respond to traditional antimicrobial therapies.
