Primary bone tumour in eastern Libya--a 10 year study.

In this study the frequency of primary bone tumours in the eastern part of Libya during a period of 10 years (1981 to 1990) is analysed. During this period 165 histologically proved primary bone tumours were seen. Out of these 165 tumours 40 were malignant and 125 were benign. Males were more frequently affected by the primary bone tumours. The second decade was the most common age of incidence for both benign and malignant tumours. The femur was the most common site. Comparison with similar studies from selected parts of the world indicated that the frequency of primary malignant bone tumours in Eastern Libya appears to be low.
