Comparing with other malignant tumors, uveal melanomas determine tardive general spreading. Even in the absence of local treatment, general metastasis is less than 20%, in the first five years, many factors being involved. This paper present a particular case of choroid melanoma with very unusual and unpredictable evolution of the disease; the high growth of tumor size (in only half year the tumor almost doubled up dimensions), was associated with hepatic metastasis developed in only several months. In our opinion, this case, presenting a very atypical evolution may contribute to increase our knowledge of the mechanisms underlying metastasis and the identification of reliable progression parameters as prognostic markers in primary uveal melanoma. Several histological characteristics and demographic factors have been associated with disease evolution: presence of retinal neovessels and neovascular glaucoma, rapid increasing tumor thickness, scleral invasion, epithelioid cell types with large nucleoli, lymphocytic infiltration, and vascular pattern with networks of loops. Sclera invasion is uncommon in choroid tumors, but it is associated with an unfavorable bad prognosis, giving a great propensity to metastasize and to affect the liver. The median survival following diagnosis of hepatic metastasis is only several months.
