This talk will summarize the basis for classification soft tissue lesions and address changes to the classification introduced in the most recent 5th Edition WHO Classification of Bone and Soft Tissue Tumors. This edition introduced a number of new entities in the classification scheme, and these will be briefly introduced. A pattern-based approach to diagnosis of soft tissue lesions will be explained, and the important microscopic features and immunohistochemical tests that distinguish various soft tissue lesions in a differential diagnosis will be discussed. The FNCLCC grading and AJCC 8th edition staging for soft tissue lesions will be explained. The gross and microscopic features of common non-neoplastic bone and joint conditions will be reviewed. The distinct clinical, radiographic, gross, and microscopic features that distinguish bone lesions will be discussed. The appropriate handling of bone specimens will be reviewed. The grading and AJCC 8th edition staging of bone tumors will be explained.
At the end of the sessions, participants will be able to:
- Summarize the classification of bone and soft tissue lesions.
- List new entities in the 5th Edition WHO Classification of Bone and Soft Tissue Tumors.
- Describe the gross handling of bone and soft tissue specimens.
- List the microscopic, immunohistochemical, and molecular features that distinguish various bone and soft tissue lesions.
- Discuss the grading and AJCC 8th edition staging of bone and soft tissue tumors.
