Abstract
Verrucous venous malformation (VVM) is a vascular malformation that is rarely reported in the literature which has vascular and hyperkeratotic components affecting mainly the extremities, difficult to treat, and often associated with complications mainly bleeding, ulceration with secondary infections, and limitation of movement. In this article, we report a successful improvement of VVM with sirolimus. (C) 2021 The Author(s). Published by S. Karger AG, Basel
