Dermoid cysts are benign tumors that represent the simplest form of teratoma (1). Approximately 7% of dermoid cysts affect the head and neck region, and within this region, they are commonly found along the orbital walls(2). Orbital dermoid cysts occur most commonly along the lateral aspect of the orbit, in approximately 69% of cases. Intraorbital location is relatively rare for these lesions. ...
INTRODUCTION The frequency of intra-orbital metastasis in systemic cancer is a controversial topic. Of all metastatic tumors to the orbit of the eye, breast carcinoma is considered to be the most prevalent. Orbital findings typically present themselves after the diagnosis of the primary tumor, with an average delay of three to six years. In spite of that, this study reports a case in which orbi...
Utilizing the conceptual combination of brain protective skull base surgery and minimalism, a conventional frontal craniotomy for tumors in the subfrontal and parasellar regions is modified to an orbital roof craniotomy. Through a 4 to 5 centimeter (cm) long eyebrow incision an orbital roof craniotomy (measuring 2 cm by 3 cm), including the supraorbital arch, is made as a single piece bone flap...

Ocular involvement is seen in approximately 25% of patients with sarcoidosis. Uveitis is the most common ocular manifestation, but sarcoidosis may involve any part of the eye. Orbital manifestations of sarcoidosis are uncommon with few series in the literature. A 65-year-old woman presented with redness of the right eye and painless, unilateral eyelid swelling. Orbital scanning revealed mass in...
A 12-year-old girl had a 6-year history of a large soft-tissue mass in her left orbit. The tumor biopsy was previously performed elsewhere when she was 7 years old, but no treatment was offered at that time. Later, the tumor was completely excised, and histologic examination revealed a mesenchymal neoplasia with typical hemangiopericytoma features. At 9 months of follow up, no evidence of local...
Compared to other organs, the eyes are relatively infrequent sites of metastasis. In a landmark case series, Ferry and Font described 227 cases of carcinoma metastatic to the eyes. Among these cases, only 28 (12%) were orbital metastases, most frequently from tumors of the breast, lung, and genitourinary tract; in this series, the diagnosis of orbital metastasis preceded the diagnosis of the pr...
Spheno-orbital meningioma have traditionally been defined as secondary tumors of the orbit originating from the dura of the sphenoid wing bone. Nevertheless, pathologic findings reveal a distinct periorbital component as a defining feature of these lesions. These tumors are characterized by an intraosseous mass growth leading to a significant hyperostosis involving the sphenoid wing, the orbita...
BACKGROUND The purpose of this study was to evaluate the frequencies of various types of orbital lesions seen at a comprehensive cancer center in the United States. METHODS In this retrospective case series, we reviewed the medical records of 268 consecutive patients referred to our orbital oncology service for evaluation of an orbital mass between November 1998 and February 2009. Each orbita...
INTRODUCTION Rhabdomyosarcoma is the most common primary orbital malignant tumor in children. Orbital lesions represent about 10 % of all the cases of rhabdomyosarcoma. Rhabdomyosarcoma is a rare cause of proptosis in adults. OBJECTIVE To report a case of primary orbital rhabdomyosarcoma in a 45-year-old female. DESIGN Interventional case report. The main outcome measures are a rare cause o...
