title: Subcutaneous ("inverted") verrucous carcinoma with bone invasion.
abstract: Verrucous carcinoma (VC) is a low-grade cutaneous squamous carcinoma which often presents on the foot where it is known as carcinoma cuniculatum. Three cases of VC on the buttock have previously been documented. We describe a highly unusual example of VC involving the buttock with extensive iliac bone erosion, and with the apparently unique feature of being totally subcutaneous.
