chondroid matrix

chondroid matrix

The ground substance of cartilage, which contains:
• Type II and X collagen;
• Chondroitin 4-sulphate;
• Chondroitin 6-sulphate;
• Keratan suphate;
• Aggrecan core protein.

This is explained by the fact that the signal intensity on T1- and T2-weighted MRI images in CBT is dependent on the amounts of various components within the lesion, such as chondroid matrix, cellularity, calcification, hemosiderin, and aneurysmal bone cyst-like areas.
It showed bony trabeculae entrapped by lobules of chondrocytes with chondroid matrix exhibiting pleomorphism, hyperchromasia, mitosis, area of myxoid change and necrosis consistent with well-differentiated chondrosarcoma.
Presence of extensive surrounding reactive edema within the marrow and soft tissues, sclerotic margin, and presence of chondroid matrix are helpful features distinguishing chondroblastoma from GCT.
The mature chondrocytes are situated in a chondroid matrix.
Chondroid matrix and edema generate high signals, while signals are reduced with ossification.
Tumor subtype was assigned according to terminology and criteria defined in the World Health Organization Classification for Bone and Soft Tissue Tumors, (3) with the exception of chondroblastic subtype, which we defined as any high-grade osteosarcoma with at least 5% of the tumor containing neoplastic chondroid matrix.
Enchondromas are centrally located, geographic, and predominantly lytic-appearing lesions, which almost invariably contain a chondroid matrix when found in the long bones (Figure 5).
Findings on CT include a hypodense soft-tissue mass with scattered chondroid matrix calcifications.
Chondroid matrix mineralization, which is sometimes recognizable on lateral chest radiographs, is better depicted on CT images, on which it appears as multiple stippled calcifications.
Histologically, a vaguely multilobulated pattern comprising a variable admixture of myxoid and chondroid matrix was observed in all 51 cases, regardless of the subtype.
There are coarse calcifications in the center of the lesion that represent the chondroid matrix, which is frequently a characteristic of chondroid tumors.
The histologic sections revealed lobules of circumscribed lesions made up of small chondrocytes with round nuclei in the lacunae and an intervening hematoxylin and eosinstained chondroid matrix.
