Rare Tumours in Maxillary Region

Abstract

Introduction: Malignant tumours located in maxillofacial region represent approximately 2-3% of all cancers and thus belonging to 10 most frequent malignancies. Approximately 85 to 95% of oral cancer is squamous cell carcinoma, which is well known type of cancer. Background: In these articles we report two uncommon tumors of maxillofacial region, which we encountered on department of Oral and Maxillofacial Surgery University Hospital Brno. The first rare tumour is chondroblastic osteosarcoma with incidence 0,07 cases per 100 000 population per year, the second is glomangiopericytoma, which represents 3% of all tumors of head and neck. Chondroblastic osteosarcoma is highly malignant tumor, while glomangiopericytoma belongs to category of borderline and low-malignant-potential soft-tissue tumors.
