Impact of the COVID-19 Pandemic on Characteristics of Cutaneous Tumors Treated by Mohs Micrographic Surgery.

The COVID-19 pandemic has impacted the practice of Mohs micrographic surgery (MMS). We sought to determine the characteristics of skin cancers treated by MMS during the pandemic compared with prepandemic controls. A retrospective chart review was conducted. Tumors included were all treated in accordance with best practice guidelines set forth by state- and national-level professional governing bodies. Bivariate and multivariate analyses were performed to compare outcome variables. Changes in tumor characteristics during the pandemic are of clinical significance, potentially affecting extent of reconstructive surgery, cost, operating time, and future tumor characteristics.
