Extrapulmonary Small Cell Carcinoma Presenting as an Orbital Mass: A Case Report.

Cureus 2022 Jun 16;14(6):e26012. Epub 2022 Jun 16.

Hematology and Oncology, East Orange Veterans Affairs Medical Center, East Orange, USA.

Extrapulmonary small cell carcinomas (ESCCs) are poorly differentiated neuroendocrine tumors that are characterized by an aggressive course and poor survival rates. While these tumors can be found anywhere in the body, presentations of lesions in the orbit are exceedingly rare. We present the case of a 47-year-old man who presented with blurry vision, lacrimation, and tenderness of his right eye, as well as a small but palpable temporal mass. Read More

Endoscopic Endonasal Supraoptic and Infraoptic Approaches for Complex "Parasuprasellar" Lesions: Surgical Anatomy, Technique Nuances, and Case Series.

Front Oncol 2022 26;12:847250. Epub 2022 May 26.

Department of Neurosurgery, The First Affiliated Hospital of Nanchang University, Nanchang, China.

Objective: The surgical management of lesions involving the lateral area of the suprasellar region, including the lateral aspect of the planum sphenoidale and the tight junction region of the optic canal (OC), anterior clinoid process (ACP), and internal carotid artery (ICA) and its dural rings, is extremely challenging. Here, these regions, namely, the "parasuprasellar" area, are described from the endonasal perspective. Moreover, the authors introduce two novels endoscopic endonasal supraoptic (EESO) and endoscopic endonasal infraoptic (EEIO) approaches to access the parasuprasellar area. Read More

Hematic Pseudocyst Masquerading as Orbital Cellulitis and Sinusitis.

Case Rep Ophthalmol 2022 Jan-Apr;13(1):265-269. Epub 2022 Apr 13.

Department of Ophthalmology, University of Colorado, Aurora, Colorado, USA.

Hematic pseudocysts are fibrous, nonepithelial lined capsules containing blood byproducts that typically present remotely following orbital fracture hardware implantation. Trauma, implant migration, and tissue erosion are believed to cause hemorrhage to pool within the capsular space. Risk factors include inadequate posterior fracture reduction and use of nonporous material which prevents fibrovascular ingrowth and stabilization. Read More

[Dolenc's Approach:Anterior Clinoidectomy and Extradural Approach to Cavernous Sinus].

Authors:
Kentaro Mori

No Shinkei Geka 2022 May;50(3):595-604

Department of Neurosurgery, Tokyo General Hospital.

The combined epidural and subdural approach pioneered by Dolenc allows opening of the lateral wall of the cavernous sinus(CS)to treat various pathologies such as tumors and aneurysms in the cavernous, para-cavernous, and central skull base regions. The Dolenc's approach is occasionally performed with the orbitozygomatic approach(OZA), which enables us to look up highly located lesions. We prefer the two-piece method when performing OZA: it involves removing the orbitozygomatic bar separately after frontotemporal craniotomy. Read More

Laser Treatment for Choroidal Melanoma: Current Concepts.

Surv Ophthalmol 2022 May 26. Epub 2022 May 26.

Department of Ocular Tumor, Orbital Disease and Ophthalmic Radiation Therapy, The New York Eye Cancer Center, 115 East 61st Street, New York City, New York, USA, 10065.

Laser treatment has offered a relatively nonsurgical alternative for eye, life, and vision-sparing treatment of malignant melanoma of the choroid. Historically, the most commonly used forms of lasers were xenon-arc, argon laser, krypton laser, and the more recent transpupillary thermotherapy (TTT) and photodynamic therapy (PDT). Melanomas selected for laser treatment tend to be smaller and visibly accessible, which means these tumors are usually located in the posterior choroid. Read More

Anterior Petrous Rhomboid Approach for Petroclival Chondrosarcoma.

World Neurosurg 2022 May 27. Epub 2022 May 27.

Department of Neurosurgery, All India Institute of Medical Sciences, New Delhi, India.

Access to the petroclival region has always been a matter of formidable challenge due to the surrounding neurovascular structures. The ideal approach to the region is dependent not only on the specific tumor characteristics but also on surgeon's preference. In this article, we have highlighted the use of modified Dolenc Kawase (MDK) approach to expand the standard anterior petrosectomy corridor for challenging tumors that need additional exposure.

Does reconstruction affect outcomes following exclusively endoscopic endonasal resection of benign orbital tumors: A systematic review with meta-analysis.

World J Otorhinolaryngol Head Neck Surg 2022 Mar 31;8(1):25-35. Epub 2022 Mar 31.

Division of Rhinology and Endoscopic Skull Base Surgery, Department of Otolaryngology-Head and Neck Surgery University of Washington Seattle Washington USA.

Objective: As exclusively endoscopic endonasal resection of benign orbital tumors has become more widespread, high-quality outcomes data are lacking regarding the decision of when and how to reconstruct the medial orbital wall following resection. The goal of this study was to systematically review pertinent literature to assess clinical outcomes relative to orbital reconstruction practices.

Orbital involvement in lacrimal drainage disorders.

Saudi J Ophthalmol 2021 Jul-Sep;35(3):204-208. Epub 2021 Nov 17.

Govindram Seksaria Institute of Dacryology, L.V. Prasad Eye Institute, Hyderabad, Telangana, India.

Lacrimal sac is situated anterior to the orbital septum, which acts as a barrier, thus limiting the posterior migration of the pathologies affecting the lacrimal drainage system. Certain pathologies can breach this barrier and secondarily involve the orbit causing significant clinical manifestations. This posterior migration of pathology also has a significant influence on the management and outcomes. Read More

Dual ophthalmic arteries: a new case.

Surg Radiol Anat 2022 May 22;44(5):721-725. Epub 2022 May 22.

Faculty of Medicine, Department of Radiology, Hacettepe University, 06100, Ankara, Turkey.

We report one retinoblastoma patient with dual ophthalmic arteries (also known as "double ophthalmic arteries") arising from the internal carotid artery which fuse with each other inside the orbit. The caudal ophthalmic artery with larger caliber originated from the cavernous segment of internal carotid artery and passed through the superior orbital fissure. The cranial and tiny one arose more cranially from the supraclinoid internal carotid artery and passed through the optic canal. Read More

Cyclin D1 expression and molecular genetic findings in periocular histiocytoses and neoplasms of macrophage-dendritic cell lineage.

Am J Ophthalmol 2022 May 17. Epub 2022 May 17.

Department of Pathology, Wills Eye Hospital, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, PA, USA; Department of Ophthalmology, Wills Eye Hospital, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, PA, USA.

Purpose: Frequent activating mutations in the mitogen-activated protein kinase (MAPK) pathway genes have been identified in histiocytoses. MAPK signaling consistently upregulates Cyclin D1. The goal of this study was to determine whether Cyclin D1 expression by immunohistochemistry is a useful diagnostic marker for periocular histiocytoses and to further characterize their genetic basis.

Navigational Transmaxillary Endoscopic Approach for Inferomedial Tumors.

Front Oncol 2022 27;12:804070. Epub 2022 Apr 27.

Department of Ophthalmology, Taipei Veterans General Hospital, Taipei, Taiwan.

Orbital tumors encompass a heterogeneous range of histopathology and usually variable in location. Traditionally, transconjunctival medial orbitotomy is used to access the medial orbital wall. However, it creates potential risk of soft tissue sequelae such as scarring, lid contracture, or entropion/ectropion. Read More

Sulfated Hyaluronan Binds to Heparanase and Blocks Its Enzymatic and Cellular Actions in Carcinoma Cells.

Int J Mol Sci 2022 May 2;23(9). Epub 2022 May 2.

Department of Biochemistry, Hoshi University School of Pharmacy, 2-4-41, Ebara, Shinagawa-ku, Tokyo 144-8501, Japan.

We examined whether sulfated hyaluronan exerts inhibitory effects on enzymatic and biological actions of heparanase, a sole endo-beta-glucuronidase implicated in cancer malignancy and inflammation. Degradation of heparan sulfate by human and mouse heparanase was inhibited by sulfated hyaluronan. In particular, high-sulfated hyaluronan modified with approximately 2. Read More
