[Interstitial substance of a chondrosarcoma (a histochemical study].

The content of acid mucopolysaccharides of the interstitial matrix of various structural variants of chondrosarcoma was studied in the operation material of 28 chondrosarcomas. The chondrosarcoma tissue contained a large amount of sulphated mucopolysacharides and a low amount of hialuronic acid. The quantity and quality of mucopolysaccharides directly depended on the degree of maturity of the tumour tissue which was reflected morphologically in the scarcity of intercellular substance in the tissue.
