What does a lymph node that has been infected by melanoma look like?

Lymph node melanoma: A lymph node with melanoma may not look like anything. It may not feel like anything at all and may be detected only with microscopic examination. Under the microscope, the lymph node will have some melanoma cells. They are also sometimes difficult to find and special stains may be needed to look for them. If you suspect you may have a melanoma, please see your dermatologist asap.

Varies: The most visually striking are dark and black when cut open. Amelanotic melanomas may be non pigmented. Sizes vary from microscopic to huge. They may bulge from skin or not be palpable. Diagnosis requires biopsy. Sometimes fine needle aspiration will suffice.

Varies: The lymph node may have a normal physical exam and only have microscopic evidence of melanoma. Or the lymph node may be enlarged and firm if it has macroscopic evidence of melanoma.
