Abstract

Background/Purpose:

To present a case report of retinal metastasis of laryngeal squamous cell carcinoma that was diagnosed by a histopathologic finding from the surgically extracted tumor tissue.

Methods:

A 66-year-old man, who was suffered from the treatment-resistant laryngeal carcinoma, was referred to our department because of visual field defect in his right eye. A fundus examination revealed a parafoveal white retinal lesion, which rapidly expanded to the central fovea and decreased the visual acuity. A tissue extraction by 27G pars plana vitrectomy was performed to confirm the diagnosis.

Results:

The abnormal retinal tissue was extracted en block through 10-mm sclerocorneal tunnel during pars plana vitrectomy. The histopathologic findings revealed that the retinal lesion was retinal metastasis of laryngeal carcinoma.

Conclusion:

We must keep in mind that retinal metastasis can be one of the differential diagnoses for white retinal lesions of unknown cause.
