Clinicopathologic analysis of a case of small cell lung carcinoma metastatic to the retina.

PURPOSE: Tumor metastases to the retina are a relatively rare occurrence. We report a unique case of retinal metastasis of a systemic malignancy with clinical and histopathologic correlations.

OBSERVATIONS: A 62-year-old female with a history of stage IV small cell carcinoma of the lung (SCC, status post chemotherapy and maintenance immunotherapy) presented with hand motions vision and vitreous hemorrhage, status post prior vitrectomy and biopsy that was non-diagnostic. She was found to have unilateral retinal metastatic tumor and underwent a repeat vitrector-assisted biopsy which confirmed the diagnosis. The eye became blind and painful due to recurrent non-clearing vitreous hemorrhage and ghost cell glaucoma and was enucleated. Detailed histopathologic analysis of the globe confirmed small cell carcinoma metastatic to the retina and vitreous cavity and sparing the choroid.

CONCLUSIONS AND

IMPORTANCE

This case demonstrates the importance of maintaining a high index of suspicion for metastasis in patients with a known history of malignancy who present with new vitreoretinal lesions.
