Routine excision of dysplastic nevi (DN) showing moderate to severe atypia with clear margins on the shave removal specimens (SRS) is not necessary, according to a recent study. Researchers reviewed 426 SRS diagnosed with DN showing moderate or severe atypia between January and December 2015, along with their post-shave excision specimens. Clear or negative margins on the SRS were defined as neoplastic melanocytes confined within >0.2 mm of the lateral and deep specimen margins. Researchers found:

• With a negative predictive value of 98.4%, DN showing moderate or severe atypia with clear margins are most likely removed by the shave procedure.

• Regular surveillance of DN is sufficient.
