Abstract. Purpose:To report a case of choroidal malignant melanoma treated by enucleation. Case and Findings:A 59-year-old woman presented with impaired vision in her left eye since 2 months before. Her corected visual acuity was 1.2 right and hand motion left. The left fundus showed a gray and partially black elevated lesion superior and nasal to the optic disc. Flat retinal detachment was present in the macular area. Magnetic resonance imaging(MRI)showed a tumor of 6mm in height and 10mm across. It showed high intensity by T1-weighted image and low intensity by T2-weighted image. Findings by echographe and fluorescein angiography were also suggestive of malignant melanoma. Systemic examinations ruled out metastasis of malignant tumor to or from the choroid. The left eye was enucleated as radiotherapy was contraindicated because of vicinity of the tumor to the optic disc. The tumor was diagnosed with mixed cell type malignant melanoma. There was no infiltration of tumor cells to adjacent tissues. Conclusion:Choice for treatment is still controversial for middle-sized choroidal malignant melanoma. We opted for enucleation because of above reasons.
