Perianal and anal skin cancers treated with Mohs micrographic surgery and interdisciplinary care: Local recurrence rates and patient- reported outcomes

To the Editor: Perianal and anal skin cancers treated with conventional excision have high local recurrence rates. 1 Maccabe T.A. Parwaiz I. Longman R.J. Thomas M.G. Messenger D.E.

This study evaluated local recurrence rates, patient-reported outcomes (PROs), and the frequency of interdisciplinary care for perianal skin cancers treated with MMS.
