What is metastatic melanoma?
Metastatic melanoma is melanoma that has spread beyond the skin to other organs. There are several types of metastatic melanoma. There may be spread through the lymphatic system to local lymph nodes. This may show up as swollen lymph glands (usually painless) or as a string of skin tumors along a lymphatic chain. Melanoma may also spread through the bloodstream (hematogenous spread), where it may appear in one or more distant sites, such as the lungs, liver, brain, remote skin locations, or any other body location.
