CD163 and chondrosarcoma: In a study by Richer et al. [35], TAMs appeared to be the most abundant immune population both in the peritumoral area of conventional chondrosarcomas and in the dedifferentiated areas of dedifferentiated chondrosarcomas, compared to TILs (25% were CD163+ TAMs in conventional and 50% in dedifferentiated, compared to, respectively, 10% and 15% being CD3+ cells, and 8% and 5% being CD8+ cells).
