Although dermatofibromas are by far the most common cutaneous mesenchymal tumors, a vast array ‎of other mesenchymal neoplasms may also be encountered in the skin, ranging from trial benign ‎lesions to highly aggressive sarcomas. Our understanding of such neoplasms has evolved considerably ‎with the discovery of disease-defining molecular genetic alterations and the development of much ‎more specific diagnostic markers. This lecture will provide an update on cutaneous mesenchymal ‎tumors, with an emphasis on a pattern-based diagnostic approach and application of novel ‎immunohistochemical markers.‎

Learning Objectives
Upon completion of this lecture, participants should be able to:‎
  • Utilize pattern-based diagnostic approach to differentiate between histologic features of diverse ‎cutaneous mesenchymal tumors.‎
  • Apply immunohistochemistry to improve diagnostic accuracy of cutaneous mesenchymal tumors.‎
  • ‎Employ molecular genetic testing for selected cutaneous mesenchymal tumors.‎
