Satellites: Satellite lesions are nodules of tumor/melanoma located more than 0.05 mm from the primary lesion. Satellites are described as being present or absent.
Seborrheic Keratosis: Benign skin lesion associated with aging and sun exposure; not precancerous.
Secondary Deposit: means the same thing as metastasis, i.e. the disease has spread from its site of origin. This does not necessarily mean that the disease is incurable.
Sentinel Lymph Node: The first lymph node to which cancer is likely to spread from the primary tumor.
Sentinel Node Biopsy (SNB or SLNB): Injecting a small amount of radioactive dye into the area of the primary melanoma to scan for melanoma cells in the sentinel nodes. Removal and examination of the first lympth node(s) to which cancer cells are likely to spread from a primary tumor.
