Cytogenetic findings in benign cartilaginous neoplasms.
Cytogenetic analysis has improved our understanding of the histopathogenesis of many benign and malignant bone and soft tissue tumors, as well as served as an important diagnostic adjunct for these pathologic entities. Cytogenetic reports of benign cartilaginous tumors, however, are relatively few. This is unfortunate, as distinguishing benign and malignant cartilaginous neoplasms can often be difficult. In this study, the cytogenetic findings of two enchondromas, two periosteal chondromas, and one soft part chondroma and a review of the literature are reported. Abnormal diploid or near-diploid clones were detected in all specimens analyzed. Although a tumor-specific anomaly did not emerge from these studies, involvement of certain chromosomes/chromosomal regions appears recurrent.
