Is it time we changed the way we manage melanoma in situ of the trunk and limbs?

Abstract

There is little evidence on the optimal clinical and histological margins required to reduce local recurrence in melanoma in situ (MIS). Our aim was to identify the number of lesions on the trunk and limbs with histological clearance > 1 mm after initial narrow-margin excision. In our cohort 93.6% were considered clear after initial exclusion with no residual MIS seen when further wide local excision was carried out.
