USCAP Updates from the New WHO Classification of Soft Tissue and Bone Tumors 2020 (CME VIDEOS)


Course Description

The diagnosis of soft tissue and bone tumors can be a significant challenge, even to the experienced surgical pathologist, due to the rarity of such tumors, the broad morphological spectrum of mesenchymal neoplasms, and overlap with other soft tissue and bone tumors and non-mesenchymal neoplasms. The classification of soft tissue and bone tumors continues to evolve, following the description of “new” tumor types, the discovery of novel molecular genetic alterations, and the development of increasingly specific diagnostic immunohistochemical markers; these changes are included in the new World Health Organization (WHO) Classification of Tumours of Soft Tissue and Bone. Surgical pathologists are not familiar with the current classification of soft tissue and bone tumors and recently developed diagnostic markers and struggle with accurate diagnosis. This course, presented by experts, will help to alleviate that struggle and provide pragmatic information for immediate practice improvement.
