Malignant choroidal melanoma with suspected vitreous seeding - A case report

Retinal perforation with vitreous seeding is an uncommon condition of treatment-naïve choroidal malignant melanoma. We reported a 52-year-old male who had a pigmented tumor protruding from choroid of his right eye. He had only black shadow sensation for 4 months then a rapid deterioration of vision. Fundus examination showed vitreous haze with many pigmented materials. B-scan ultrasonography revealed a mass with low internal reflectivity and vitreous opacity. The eyeball was enucleated and a stage IIIA melanoma was confirmed by the pathologist. No local recurrences or metastases were found during 31-month follow-up. Although vitreous seeding may indicate rapid tumor growth, early enucleation may insure a better prognosis.
