Melanoma micrometastases, or micromets, consist of small groups of melanoma cancer cells that have spread through the lymphovascular system. The presence of metastasis in sentinel lymph nodes (SLN) can indicate that cutaneous melanoma has spread to other sites, aiding in the diagnosis, prognosis, and therapy decisions. SLN status is a strong predictor of survival in clinical stage I/II melanoma patients. The most accurate way to assess lymph node metastasis is through histologic evaluation using a microscope, as many patients may have lymph nodes that appear clinically negative.
