Cavernous hemangioma is the most frequent primary benign vascular tumor of the orbit in the adult; the median age of diagnosis is 42 years with a female predominance. This tumor develops slowly and has no tendency for spontaneous regression; it is electively located at the level of the retro-ocular muscular cone but it can develop in the extraconic space. Clinically it appears as progressive irreducible, non-pulsating, painless (unless there's an unexpected complication) exophthalmia, associated with decrease in visual acuity in 2/3 of cases...

Metastatic tumor is one of several etiologies of space-occupying masses in the orbit that accounts for 1-13% of all orbital masses. In the adult patient population, breast cancer is the most common tumor to metastasize to the orbit, followed by metastasis from the lung, prostate, and gastrointestinal tract. Carcinoid tumors are rare neuroendocrine neoplasms derived from enterochromaffin cells, which are found primarily in the gastrointestinal tract and bronchial tree. Liver metastases are the classic presentation of distant disease...

BACKGROUND: Surgical access to Meckel's Cave (MC) is challenging due to its deep location and surrounding important neurovascular structures. Currently existing endoscopic endonasal (EE) approaches require dissecting near the internal carotid artery (ICA) or require transposition of the pterygopalatine neurovascular bundle. OBJECTIVE: To describe a novel approach to access the anterolateral aspect of the MC using a minimally invasive EE route. METHODS: The EE transmaxillary transinferior orbital fissure approach was simulated in 10 specimens...

Basal cell carcinoma (BCC) is a common malignant tumor throughout the world. One of the known risk factors of BCC is intense exposure to ultraviolet radiation. More than 50% of BCCs of the eyelid initially occur on the lower lid. The gold standard of diagnosis of BCC is histopathology. Treatment options for BCC consist of surgery, vismodegib, radiotherapy and imiquimod. Surgical excision using Mohs micrographic surgery or wide surgical excision with frozen section margin control is the first consideration for treatment of periocular BCC...

Current surgical removal of sphenoorbital meningiomas (SOM) mainly aims at reduction of proptosis and restoration of visual function; some stages of the surgical technique are controversial. In this study, we aim to present a surgical decision-making algorithm for SOM. A retrospective study of 27 patients who underwent resection of SOM in our center (2005-2014) was conducted. The primary outcomes evaluated were postoperative visual function and radiological exophthalmos. In our study, clinical proptosis was the most common presenting sign (92%), followed by visual loss (37%)...

Glutathione (γ-l-glutamyl-l-cysteinyl-glycine) is a ubiquitous tripeptide found in all plants and animals. Glutathione has key roles as a metallochaperone and as a cellular thiol involved in metabolism. Little is known about how glutathione interacts with organometallic compounds in vivo. Here, we report the reactions of glutathione in vitro with dirhodium(ii) tetraacetate (tetrakis(μ-acetato)dirhodium(ii), Rh2(OAc)4), a compound with anti-tumour properties. Electrospray ionization mass spectrometry, UV-Visible absorption and circular dichroism spectroscopic methods were used to determine the stoichiometries and optical properties of the final conjugate...

Background Tumors of the lacrimal duct are rare. Inflammatory pseudotumors do not represent neoplasias as such. Chronic inflammation may lead to an angiomatous granulation tissue. Patients The first case presents a 53-year-old male patient suffering a mass of the mediocaudal orbit after an acute dacryocystitis has been cured. Using diagnostic dacryoendoscopy, a large dacryolith was detected. Removing the concrement, via external dacryocystorhinostomy, a polypous tissue appeared which was resected as well. The second case concerns a 29-year-old female patient...
