For a T1 lesion, 1-cm excision margins are adequate, but lesions greater than 1 mm require 2-cm margins. Studies demonstrate no improvement in recurrence or survival rates with larger margins of resection. Attempt primary closure and perform skin grafting or flap closure if necessary. For lesions with a depth greater than 1 mm, many authorities recommend sentinel lymph node biopsy at the time of wide local excision (see Stage II).
