Pathologist's Report

Bone biopsy from lesion in distal right femur. The specimen consist of three cores, the longest measuring 8mm, which are processed in one cassette and decalcified. 

Histology shows fragments of hyaline cartilage in which there is no significant increase in cellularity or cytological atypia. Fragments of cortical bone are also present. In one area cartilage is adjacent to bone. However there is no evidence of a permeative pattern or any overt features of malignancy.

The figures are consistent with enchondroma. There are no findings to suggest chondrosarcoma in this sample.
