A primary malignant melanoma will most likely metastasize to which organ?

Explanation:
Melanoma commonly spreads through the bloodstream to distant organs, and among visceral sites the liver is the most frequent target. The liver’s rich blood supply and its network of sinusoids readily trap circulating melanoma cells, allowing them to lodge, colonize, and grow there. While brain and lungs can also harbor metastases, and metastasis to the heart is relatively rare, the liver most often becomes the first and most common site of distant spread for a primary melanoma.
