Abstract
This review shows the extraordinary change molecular pathology has induced in the classification, diagnosis, and clinical practice of molecular pathologists dealing with sarcomas. We have primarily focused on the practical aspects of molecular studies and the current and mid-term challenges for our subspecialty, ending with ten tips for the next generation of sarcoma molecular pathologists.

Abstract
Since the introduction of new molecular techniques, the diagnostic landscape of soft tissue and bone tumors has expanded greatly over the past few years. The use of new molecular techniques has led to the identification of new genetic alterations and, therefore, to a better understanding of tumorigenesis, tumor detection and classification. Furthermore, methylation profiling has emerged as a classification tool for soft tissue and bone tumors. Molecular pathology also plays an important role in the determination of patient prognosis and in the identification of targets that can be used for targeted therapy. As a result, molecular pathology has gained a more prominent role in the daily practice of the surgical pathologist. This review delves into various molecular techniques applied in the surgical pathology of soft tissue and bone tumors. It highlights their applications through the analysis of five specific cases.
