cone.7 Orbital tumors are classified into primary and secondary orbital tumors.2Primary orbital tumors include benign and malignant neoplasms. The direct extension from contiguous anatomical structures, lymphoproliferative disorders, and hematogenous metastasis result in secondary orbital invasion.6 Also the proximity of the paranasal

An introductory overview of orbital tumors

Orbital tumors constitute a heterogeneous array of le-sions (Table 1) and, as such, pose numerous challenges in terms of diagnosis, imaging and management. 2,5 Given the variety of structures within the relatively confined orbit, a systematic approach is necessary to understand the classi-fication and clinical features of orbital tumors. Schemat-

Experience with Orbital Tumors from a Tertiary Cancer Centre

Orbital Tumors Chowdhury et al. Introduction Orbital malignancies are an important group of disorders presenting in all age groups. Malignant tumors of the orbit may originate either from the primary orbital tissues includ-ing the eyeball, or may invade from surrounding structures like eyelids, paranasal sinuses, nasopharynx, or cranial cav-

Case Report Orbital leiomyosarcoma metastasis presenting

orbital tumors are thought to originate in primitive repli-cating cells associated with blood vessels in the poste-rior orbit and possibly Mueller s muscle when present in the anterior orbit. In metastatic lesions, the primary tumors are often pelvic, cutaneous, or gastrointestinal in origin.

meningoceles and encephaloceles, can involve the orbit via the orbital fissures or bony defects [3]. 2.3 Vascular Tumors Vascular lesions are the second most common orbital tumors in children and the most common orbital tumors in adults [1, 5]. There is some debate as to the classi-fication and naming of these tumors.

ORBITAL TUMORS & SURGICAL APPROACHES TO THE ORBIT

Orbital tumors can be classified based on origin: 1) Primary lesions, which originate from the orbit itself; 2) Secondary lesions, which extend to the orbit from neighboring structures and include such lesions as intracranial tumors and tumors of the paranasal sinuses that, by contiguity, extend to involve the orbit; and

Nonosseous, extraocular orbital tumors are un-common in children and represent a different his-tologic spectrum than is seen in adults. Most of these lesions are mesenchymal in origin. The most common mesenchymal tumor of childhood is rhabdomyosarcoma, which may arise in or in-vade the orbit in young children. Vasculogenic

Benign orbital angiomatous tumors with intracranial extension

Orbital tumors although relatively rare with an esti-mated incidence of around 3 cases in one million people comprise a variety of benign and malignant neoplastic entities [1, 2]. Given that the orbit is encircled laterally and posteriorly by bony walls, these tumors as space-consuming lesions become most often clinically evident
