title: Cutaneous soft tissue tumors that make you say, "oh $*&%!".
abstract: Subsets of cutaneous soft tissue tumors present morphologic features which are diagnostically challenging in part because of their ability to obscure the ultimate nature of the underlying neoplastic process. This review discusses entities, which in the authors' experience, present such challenges. The clinical, histologic, immunohistochemical, and where appropriate, molecular features of these entities are discussed along with their prognosis and differential diagnosis.
