Ocular melanoma has a strong tendency to metastasize often several years after its initial diagnosis was made. We report on the case of a 50-year-old woman who was treated 20 years earlier for an ocular melanoma and currently seen regularly in our institute for liver metastases that were treated by chemotherapy. After three treatments, a check-up with computed tomography demonstrated the presence of a right ovarian mass. An ovariectomy was performed, and the pathological examination confirmed the diagnosis of an ovarian metastasis from an ocular melanoma. This is the fourth case of metastasis to the ovary from an ocular melanoma reported in the medical literature.
