Lymphoscintigraphy with Tc-99m antimony sulfur colloid was performed on a patient with cutaneous melanoma of the left forearm to define the sentinel nodes before surgery. The patient was found to have direct lymphatic drainage from the left forearm through a clearly seen lymph channel to a sentinel lymph node in the left supraclavicular fossa, and drainage through a separate channel to two sentinel nodes in the left axilla. Surprising patterns of lymphatic drainage can be seen from the forearm, as well as other parts of the skin, and lymphoscintigraphy will enable such patients to be identified before sentinel node biopsy.
