Course Description
The 5th edition of the World Health Organization (WHO) Classification of Tumors of Soft Tissue and Bone was published in 2020. The changes in the soft tissue tumor chapter include recently described tumor types; new clinically significant prognostic information for a variety of existing entities; and a plethora of novel genetic alterations, some of practical diagnostic relevance. This presentation highlights the major changes to the soft tissue chapter in the 2020 WHO Classification, as well as the new chapter on undifferentiated small round cell sarcomas, with a focus on updates in diagnostic categories, prognostication, and novel markers. Recent discoveries in molecular genetics are also discussed, particularly those of immediate utility in differential diagnosis, including protein correlates detectable using immunohistochemistry.

Target Audience
Practicing academic and community pathologists, and pathologists-in-training

Learning Objectives
Upon completion of this educational activity, learners will be able to:
  • To become familiar with recently described tumor types that have been included in the 2020 WHO Classification of Soft Tissue and Bone Tumors
  • To learn how to apply novel immunohistochemical markers that correlate with molecular genetic alterations for the diagnosis of soft tissue tumors
