When melanoma spreads (metastasizes), it usually spreads first into nearby lymph nodes. It can also spread through the bloodstream. Distant metastases of melanoma typically are found in the skin, liver, lungs, bone, and brain.
If the melanoma is on a leg or arm, metastases usually are first found higher up on that leg or arm. Unusual sites for metastases include the eye.
But symptoms of metastatic melanoma may be vague and include:
Swollen lymph nodes, especially in the armpit or groin.
