Solitary fibrous tumours are of mesenchymal origin and comprise of uncommon spindle cell neoplasias. Most commonly the lesions arise from pleura but other rarer sites include lungs, peritoneum, pericardium, nasal cavities, thyroid, parotid gland and orbit. We report the case of a 41-year-old male patient who presented to us with a painless, progressive growth of a mass in the superior part of left orbit with proptosis and inferotemporal displacement of the left eye. Computed Tomography (CT) scan revealed homogeneous enhancing lesion in the superior compartment of left orbit in the extraconal region, extending intraconally and distorting the globe...

Extraosseous osteosarcoma as a primary tumor of the neck is exceedingly rare, with only a few cases reported to date. The most appropriate therapy is still under investigation. We report a case of an aggressive, right-sided, advanced-stage extraosseous osteosarcoma in a female patient. A 48-year-old woman presented with a right-sided infra-parotid mass encompassing neck regions II and III, measuring over 6 cm in craniocaudal diameter. She was initially treated by wide surgical resection. The definitive histopathologic diagnosis was osteoblastic extraosseous osteosarcoma...

Facial nerve schwannoma is a rare intracranial tumor. Treatment for this benign tumor has been controversial. Here, we report a case of extracranial facial nerve schwannoma treated successfully by hypo-fractionated CyberKnife (Accuray, Sunnyvale, CA) radiosurgery and discuss the efficacy of this treatment. A 34-year-old female noticed a swelling in her right mastoid process. The lesion enlarged over a seven-month period, and she experienced facial spasm on the right side. She was diagnosed with a facial schwannoma via a magnetic resonance imaging (MRI) scan of the head and neck and was told to wait until the facial nerve palsy subsides...
