Sentinel lymph node biopsy for external ear melanoma: a 17 year experience with long term survival data

Melanoma of the external ear is an uncommon tumour, sparsely reported, with contrasting data regarding its prognosis.1 A recent letter from the Department of Plastic Surgery at St George's Hospital, London 2 has suggested that external ear melanoma has a lower rate of sentinel lymph node positivity which might correlate with a favourable outcome, but these data did not reach statistical significance. The study lacked long term survival data which the authors suggested was important to further interpret this result.
