Proper management of patients with biopsy-proven melanoma is vitally important. Patients with melanoma in situ, invasive melanoma <1 mm thick, and invasive melanoma >1 mm thick should have surgical resection margins of 5 mm, 1 cm, and 2 cm, respectively. All patients with melanomas >1 mm should be offered a sentinel node procedure, the most important prognostic variable in this group of patients. All patients with metastatic melanoma in the sentinel node should undergo a complete therapeutic lymphadenectomy.
Key words: melanoma, margin of resection, sentinel node biopsy.
