title: [Histochemical study of the ground substance in chordoma].
abstract: Using a series of histochemical reactions, the authors studied the intercellular substance of a chordoma and of one of its recurrences, and were able to demonstrate the presence of neutral substance, of acid mucosubstances with carboxyl groups and sulphated groups. The presence in the intercellular matrix of the chordoma of sialic acid was shown, as well as the probable presence of hyaluronic acid.
