ABSTRACT: Chondrosarcoma is a
malignant neoplasm that results in abnormal bone and cartilage growth. Although
Chondrosarcoma is rare, it is the second
most common primary bone malignancy. Mesenchymal Chondrosarcoma (MCS) is a rare
histological variant of Chondrosarcoma (CS) that accounts for only 1% of all CS
and has high predilection for the head and neck region with a peak incidence in
2nd and 3rd decade of life. There is comparable male to
female ratio with two thirds of the cases
arising from bone and one third from soft tissue. The tumor is unique because
of its aggressive growth with a high tendency for late recurrence and delayed
metastasis. We present a case of this highly malignant lesion arising from the
infratemporal fossa and rapidly involving maxillary tuberosity and mandibular
ramus.
