Hobnail Hemangioendothelioma (Dabska Type) in the Right Thigh

Introduction

Dabska tumor is a very rare vascular neoplasm [7], originally described in 1969 by Maria Dabska [6]. No ethnic or racial predilection is evident [1]. The most characteristic feature of DT is papillary endothelial proliferation with a central hyaline core [2]. This tumor has a favorable prognosis despite its potential to invade regional lymph nodes. Wide local resection is the treatment of choice [6].
