Aim: The present a rare case intraocular primary malignant choroidal melanoma. Introduction: Melanoma choroideae is most common intraocular primary tumor of adults. Incidence is 7 cases per 1 million people per year and incidence of this tumor increases with age. Case report: We report 76 years old women who had progressive visual field defects at left eye at least two years. Diagnostic examination of eye was detected a greyish-brown mass of the posterior choroidal pole which was indication for enucleation. Macroscopically bulbus oculi was dimension 28x25x25mm, with optic nerve 5mm length. At the intersection on posterior pole nearby papila of optical nerve was detected ovoid dark lesion diameters 8x3mm. Histopathology examination was showed sharply demarcated solid tumor islands which consists of epithelioid tumor cells with pleomorphic, atypical nuclei, conspicuous nucleoli. Other type of cells were spindle look which formed fascicular shapes. Pigmentation was absent also. There was no significant vascularisation in tumor mass. Sclera was superficially infiltrated by tumor cells. Mitotic activity was absent (0/40HPHF). Immunohistochemistry staining was confirmed melanoma cells: S-100, MelanA , HMB-45 /-. Conclusion: Melanoma in this region is rare, indolent lesion, with bad prognosis. Early detection could prevent further dissemination of disease and many complications. Metastatic choroid melanoma is a highly malignant disease with a limited life expectancy.
