Surgical approaches to the orbit - The past and the present
Apr 28, 2021 Orbital Tumors A B S T R A C T Tumors may occur in any part of the orbit. Their management demands either total excision or biopsy samples obtained through orbitotomy. The key to appropriate surgical management is a thorough knowledge of the anatomy and correct approach to reach the different spaces. The safest yet the most

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.

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.

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

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].
