The pathology of tumour and "tumour-like" lesions of bone in the University Hospital, Kuala Lumpur.

Summmy On the premise of establishing a local set of reference data, a retrospective study of 209 cases of osseous tumour and "tumour-like" lesions biopsied at the Universitv Hospital, Kuala Lumpur from 1980 to 1986 was carried out. The parameters studied were sex, age, ethnic distribution and sites of involvement. 135 (64.6%) primary bone tumours, 53 (25.4%) metastatic lesions and 21 (10.0%) "tumour-like" lesions were seen. Osteosarcoma (16.7%) was the commonest malignant primary tumour biopsied while osteochondroma (12.9%) widely eclipsed the other benign entities. Ethnically, the Chinese predominated among patients with metastatic lesions, osteosarcoma and giant cell tumour. Age and sex distribution resembled other published series. In the more important tumour categories, the femur was the most frequently implicated site.
