OBJECT Orbital tumors can be divided schematically into primary lesions, originating from the orbit itself, and secondary lesions, extending to the orbit from neighboring structures. These tumors are variable in their biological nature and in their location. The authors evaluate 41 cases of benign and malignant tumors involving the orbit and discuss the surgical challenge, which involves tumor ...

Aneurysmal bone cyst (ABC) is benign vascular lesion destructing the cortical bone by the expansion of the vascular channel in the diploic space that usually involve long bone and spine. Orbital ABC is rare and the clinical symptoms deteriorate rapidly after initial slow-progression period for a few months. A 12-year-old female patient visited ophthalmologist due to proptosis and upward gaze li...

Basal cell carcinoma (BCC) is the most common periocular skin cancer and can lead to significant morbidity. We assess the effectiveness of vismodegib, a first-in-class Hedgehog signaling pathway inhibitor, in the management of periocular and orbital BCCs based on clinical response, tolerability, and orbital content preservation. All patients with periocular or orbital BCCs who met criteria for ...

PURPOSE To report the incidence of orbital space-occupying lesions in an 11-year interval study of patients examined at the Hospital das Clínicas of FMUSP, and to evaluate which are the main specialties involved in the diagnosis and treatment of such conditions. METHODS All cases of orbital space-occupying lesions in the period from 1993 to 2004 were revised. Of 924 obtained medical records, ...

BACKGROUND Granular cell tumors are rare neoplasms which can occur in any part of the body. Granular cell tumors of the orbit account for only 3 % of all granular cell tumor cases. Computed tomography and magnetic resonance imaging of the orbit have proven useful for diagnosing orbital tumors. However, the rarity of intraorbital granular cell tumors poses a significant diagnostic challenge for ...

Although conjunctival squamous cell carcinoma is known to develop as a result of chronic irritation from wearing an ocular prosthesis, orbital sebaceous gland carcinoma arising in an anophthalmic pocket is extremely rare. We report a 68-year-old female who developed a sebaceous gland carcinoma 65 years after her right eye was enucleated (at the age of three years) due to congenital glaucoma. Th...

To describe a patient with unilateral metastatic choroidal gastric adenocarcinoma as a first sign of systemic dissemination. A 54-year-old woman presented with a 7-month history of progressive pain and decrease in vision in her left eye. She had undergone total gastrectomy due to gastric adenocarcinoma two years previously. Examination of the left eye revealed an elevated creamy yellow choroida...

BACKGROUND Orbital exenteration (OE) is a disfiguring procedure most commonly performed for locally advanced and potentially life-threatening periorbital malignancies. METHODS We retrospectively reviewed records of 11 consecutive HIV patients who underwent OE for invasive orbital malignancy at our institution from January 2005 to December 2015. Patient demographic and clinic data and histopat...

INTRODUCTION Dermoid cysts are the most common orbital cystic lesions seen in children. While superficial orbital dermoid cysts present early in life, deep dermoid cysts remain clinically occult until adolescence or adulthood. We here present a case of a deep orbital dermoid cyst in a Nigerian child that became symptomatic early in infancy. CASE PRESENTATION A female Nigerian infant of Yoruba...
