For the treatment of choroidal melanoma, palladium-103 (Pd) and ruthenium-106 (Ru) plaque brachytherapy shows reduced toxicity compared with the historical standard iodine-125. No report has directly compared the clinical outcomes between Pd and Ru, and the reasons for the selection of one over the other remain purely theoretical. Patients with choroidal melanoma with apical tumor height up to 5 mm were included. Patients from Emory University were treated with Pd between 1993 and 2012. Patients from Cleveland Clinic were treated with Ru between 2005 and 2010...

Optic disc melanocytoma (ODM) has been considered as a benign tumor with few reports of malignant transformation. We present swept-source optical coherence tomography (SSOCT) imaging of a case of ODM. As attaining histopathology is impossible in most cases, we discuss the possibility of using SSOCT as a tool for ruling out choroidal invasion or juxtapapillary melanoma.

Choroidal melanoma is the most common intraocular tumor in adults, and overexpression of matrix metalloproteinase-2 or matrix metalloproteinase-9 (MMP-2/MMP-9) is associated with angiogenesis and tumor metastasis of the choroidal malignant melanoma (CMM). This study aims to investigate the functions and mechanisms of microRNA or long non-coding RNA-targeted MMP-2/MMP-9 in CMM. We demonstrated that expressions of MMP-2/MMP-9 were increased in CMM tissues and C918 cells in comparison with normal choroidal melanocytes...

REVIEW
Mark R Wick
Several primary pathologic entities in diverse anatomic locations have the potential to simulate metastatic neoplasms histologically. Their misinterpretation as such may result in needless and extensive clinical evaluations that are intended to detect a presumed malignancy at another site. More importantly, mistakes of this type can deprive patients of surgical excisions that could be curative. This presentation considers a review of selected primary lesions that can simulate metastases. They include hemangioblastoma, glioblastoma and meningioma with epithelial metaplasia, choroid plexus carcinomas, primary neuroendocrine carcinomas in unusual locations, special forms of sinonasal and salivary glandular adenocarcinoma, clear-cell thyroid carcinomas, unusual microscopic subtypes of pulmonary adenocarcinoma, epithelioid myomelanocytomas ("sugar tumors"), mesotheliomas, primary thymic carcinomas, endodermal choristomas of the interatrial myocardium, peripheral cholangiocarcinoma, adrenocortical carcinoma, adenocarcinomas of the urinary bladder, mucinous and "rhabdoid" tumors of the ovaries, rete testis adenocarcinomas, interdigitating dendritic-cell sarcoma of lymph nodes, selected sweat gland carcinomas, cutaneous Merkel cell carcinoma, primary dermal and subcutaneous melanoma, mucosal and visceral melanomas, epithelioid sarcoma, clear-cell sarcoma, and adamantinoma of long bones...

Choroidal melanoma (CM), the most common intraocular tumor in adults, is still a rarity in Asia. Having a high propensity for metastasis with a poor survival, recognizing it early is essential. Although it has typical clinical features, there are instances of simulating lesions. Fine-needle aspiration biopsy can be a valuable tool not only to confirm our clinical suspicion but also aid in prognosticating it. From days of histopathological prognostic markers, we are moving on to genetic markers which are reliably providing insights, helping us in providing a better care for our patients...

Ocular or choroidal nevus (CN) is a rare benign neoplastic lesion of the eye. The cause of CN onset/progression, which arises from the transformation of ocular melanocytes, is not known. A fraction of CN patients may develop uveal melanoma. The objective of this study was to investigate the association between CN and BK polyomavirus (BKPyV), a small DNA tumor virus. Serum IgG antibodies which react with BKPyV antigens were analyzed. An indirect E.L.I.S.A. using synthetic peptides that mimic BKPyV antigens was employed...

Purpose: Adenocarcinomas or adenomas derived from pigmented ciliary epithelium (APCE) are exceptionally rare ocular tumors. These tumors have pigmented and epithelioid features, and some APCEs are negative for keratin markers and positive for melanocytic markers. It is especially difficult to distinguish APCEs from uveal melanoma (UM). Accordingly, we examined protein expression and genetic mutations associated with APCE to facilitate diagnosis. Methods: Five APCE and 11 UM samples were obtained from patients during surgical resection at our institute...

BACKGROUND: Orbital exenteration is a radical surgical procedure resulting in deformity. It involves removal of the globe, optic nerve, extra-ocular muscles, orbital fat, lacrimal gland, and peri-osteum. Sino-orbital fistula (SOF) formation is a common documented post-operative complication, usually connecting the orbit and the ethmoid sinus. SOFs can cause leaks of serous fluid, and act as an entry site for pathogens into the orbit leading to socket infection and breakdown. METHODS: This retrospective study analyzed exenterations performed over a 22-year period (1993-2015) at the National Ocular Oncology Service Centre for Scotland...
