Morphometric analysis of cartilaginous tumors

Summary 144 chondromas and chondrosarcomas have been investigated. Morpbometry has been performed: the relative volume density of tumor cell nuclei (Vv%n) and the nuclear area have been measured. The results show that the relative volume density of nuclei is a useful parameter, regarding the localisation of the tumors, to discriminate chondromas and chondrosarcomas, while the nuclear area is no safe criterion to separate these entities.
