HISTOCHEMISTRY OF SACROCOCCYGEAL CHORDOMA

A characteristic feature of chordomas is the content of a great amount of mucinous material. A sacrococcygeal chordoma surgically removed from a 76-year-old man was histochemically investigated in order to obtain some information about the composition of the mucopolysaccharides. From the results of the staining reactions, we concluded that they are of the acid category and probably a mixture of weakly sulphated and carboxylated glycoproteins.
