BCOR‐Mutated Conventional and Dedifferentiated Chondrosarcoma: A Clinicopathologic Study

Genes, Chromosomes and Cancer, Volume 64, Issue 9, September 2025.
ABSTRACT Conventional and dedifferentiated chondrosarcoma encompass a group of malignant neoplasms that produce cartilaginous matrix and arise within or on the surface of bone. Conventional chondrosarcomas are graded on a three‐tiered scale, whereas dedifferentiated chondrosarcoma is typically not graded but is considered a high‐grade sarcoma and ...
