Chondrosarcoma of mandible misdiagnosed as chondromyxoid fibroma

The diagnosis of chondrosarcoma of the jaws is often difficult due to the often indistinct boundaries between benign and malignant chondromatous tumors. In view of the often considerable variation in histological characteristics within a tumor, repeated biopsies and step sections through a specimen are recommended in difficult cases. This paper is a follow-up of the case described by DAVIS & TIDEMAN (1978) in this journal.
