However, while liver is typically not the first site of disease spread in cutaneous melanoma, ocular melanoma has been showed to primarily metastasize from the eye to the liver; indeed, liver metastases are detected in approximately 87% of patients with metastatic uveal melanoma. Therefore, liver metastasis can be challenging to identify in early stages, thus being essentially asymptomatic until the disease has advanced.
