Investigation


























             Regional lymph node basin


                  Ultrasound-guided                          fine         needle

                     aspiration cytology


                  Regions to include depends on

                     the location of melanoma


                       Head and neck: neck, parotid,

                       Upper limb: axilla, cubital fossa

                       Lower limb: groin, popliteal fossa










             Work up for distant metastasis in

                symptomatic patients or advanced

                T-stage


                  Whole body PET-CT
