Melanoma in situ lesions (MIS) are being diagnosed with increasing frequency, especially in patients with a history of sun exposure. Current practice guidelines recommend removal of the primary lesion with a margin of 5 mm to 10 mm. This study examined the risk of recurrence for MIS lesions excised with a 5-mm margin.
