OSSIFYING FIBROMYXOID TUMOR OF SOFT PARTS - A NEW TUMOR OF THE PAROTID ZYGOMATIC ARCH REGION/

The ossifying fibromyxoid tumour of soft parts was first described as recently as 1989 by Enzinger(5) has not been previously reported in th e maxillofacial literature. This tumour has a proven record of recurre nce and a potential in a few cases to become malignant and to metastas ise. Being such a rare and relatively newly described tumour it has pr oved to be difficult to diagnose and manage. In order to illustrate th ese difficulties we describe a case in which such a tumour occured in the parotid/zygomatic arch region and recurred three times following s urgical removal over a period of 24 years. Since the tumour has a pseu do-capsule containing nests of tumour cells, we recommend that it coul d be removed from the bead and neck region with a wide margin of excis ion.
