Abstract
MOTA, José D; ORELLANA, María Eugenia and ESTRIBI, Margarita. Tumores óseos orbitarios. RFM [online]. 2007, vol.30, n.1, pp.12-17. ISSN 0798-0469.
Purpose: To evaluate the rate of orbital bone tumours. Method: Our experience over a 8-year period in Instituto Anatomopatologico "Dr. J. A. ODaly" at the Universidad Central de Venezuela, yielded 17 (0.93 %) cases of orbital bone tumours from a total of 117 899 biopsies. Data were collected on patient age, sex, tumour localization and type of neoplastic disorders. Results: Ten cases (59 %) were primary tumours of orbital bone (8 benign and 2 malignant), six patients with tumour-like lesions (35 %) and one bone metastases. The two most commonly encountered entities were osteoma and fibrous dysplasia. Conclusions: Primary tumours of orbital bone constitute 0,6 % - 2 % of all orbital tumours.
Keywords : Bone; Neoplasm; Orbit; Osteoma; Fibrous dysplasia.
