LR, local recurrence (defined as recurrence within or immediately adjacent to scar because of inadequate excision and excludes local recurrences from satellite and in-transit metastasis); DSS, Disease-specific survival; MIS, Melanoma in situ (Recurrences: MIS n=3; <1mm n=1, 1.01–2.00mm n=0, 2.01–4.00mm n=1, >4.00mm n=0, excluding lost to follow-up)
