Ocular melanoma is diagnosed in approximately 6 million people annually.

Although ocular melanoma metastasizes less frequently than cutaneous melanoma (75% vs 96%, respectively), when it does metastasize, it is invariably fatal, usually within 1 year of the onset of symptoms.

Even though the liver is the most common location for metastases from ocular melanoma, it is thought that the heart is another common site that is clinically underdiagnosed.
Clinical Summary
A 75-year-old white man presented in the fall of 2000 with abdominal pain and shortness of breath. A thorough workup revealed an invasive adenocarcinoma of the cecum. A right hemicolectomy was performed on April 10, 2001, during which a biopsy of a liver lesion identified on computed tomographic (CT) scan was reported to show a metastatic adenocarcinoma. In June 2001, a resection of the left hepatic lobe and placement of an intrahepatic arterial pump were performed to treat what was thought to be metastatic colon cancer. The pathologic results later indicated that the left hepatic lesion was melanoma. Throughout this patient's course, physical examination did not reveal any suggestive skin lesions. A review of the patient's history revealed that ocular melanoma of the right eye had been diagnosed 15 years earlier, and he underwent enucleation at another center.
