Plasmacytoid dendritic cell and type I interferons as possible explanation for clearance of longstanding warts during COVID-19 in a transplant patient, reply to Erkayman et al.

We recently read with interest the article entitled "Clearance of longstanding treatment-resistant warts during COVID-19 in a transplant recipient" by Erkayman et al.1 The authors report on a 49-year-old man, known to have had renal transplantation and maintained on immunosuppressive therapy, who had a longstanding resistant warts regressing during the course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The authors speculated on possible mechanism leading to wart regression including the immunological response against SARS-CoV-2.
