Abstract

A mesenchymal chondrosarcoma is a rare malignant tumor occurring in both the bone and soft tissues, and has the characteristics of a malignant nature. Since its original description in 1959, several reports of this tumor occurring in the maxilla, mandible, rib and spine have been published. We report a case of a mesenchymal chondrosarcoma that occurred in the posterior part of C7, T1 and T2 and adjacent muscles in a 31-year-old man who was treated with a wide marginal excision.

• 

  Fig. 1. (A, B) T1-weighed MRI images show a large mass shadow in posterior neck.

• 

  Fig. 2. (A) Gross appearance of mesenchymal chondrosarcoma shows a well demarcated 9×5.5 cm sized mass with central cal-caification and ossification. (B) Microscopically a dismorphic pattern in which areas of well differentiated cartilage alternate with undifferentiated cells is characteristic.

• 

  Fig. 3. (A, B) At postoperative 6-month, MRI shows the findings of no recurrence.
