Core Tip
Core tip: We describe sentinel lymph node mapping and biopsy (SLNB) of a primary malignant melanoma in the external auditory canal. The usefulness of SLNB in this procedure allowed a focused surgical dissection to best assess regional lymph nodes and determine the extent of dissection needed to clear the disease. This novel technique is useful because it aids in establishing the single most important prognostic factor of a melanoma in the external auditory canal, regional lymph node status.
