PURPOSE: Evisceration can be performed for blind, painful eyes. This surgery can promote the dissemination of tumor cells within the orbit if an ocular tumor has been missed preoperatively. METHODS: We reviewed the medical records of patients who were eviscerated for blind, painful eyes between 2009 and 2014 and who were referred after the surgery to the Institut Curie or the Rothschild Foundation in Paris. We included the patients with a histological diagnosis of ocular tumor or orbital recurrence...

We present a case of ocular tuberculosis (TB) presenting as scleral abscess with choroidal detachment. A 60-year-old woman presented with intense pain, redness, watering and decreased vision in the right eye (RE) for 1 week duration. Slit lamp examination of RE revealed diffuse scleritis with two pus-pointing areas in the supero-temporal quadrant suggesting scleral abscess. Fundus examination of the RE showed choroidal detachment in the temporal and inferior quadrant. Left eye examination was unremarkable...

PURPOSE: Establishing the correct diagnosis of a growing choroidal tumor can be difficult. METHODS: Clinical examination and ultrasound of a patient followed for what was thought to be a uveal melanoma. Fine-needle biopsy established the correct diagnosis. RESULTS: We demonstrate that fine-needle biopsy can correctly identify a very rare tumor, a myomelanocytic neoplasm. CONCLUSION: Myomelanocytic choroidal tumors can be diagnosed on fine-needle biopsy...

Choroidal and skin metastasis of colon cancer is rare. In women, the frequency of cutaneous metastasis from colon cancer as the primary lesion in is 9% and skin metastasis occurs in 0.81% of all colorectal cancers. We report a patient with colonic adenocarcinoma who presented with visual disorder in her right eye and scalp pain as her initial symptoms. Contrast-enhance orbital magnetic resonance imaging with fat suppression revealed an infrabulbar mass, and skin biopsy of the posterior parietal scalp confirmed adenocarcinoma...

Ocular involvement in sarcoidosis is present in up to one third of patients and is frequently manifested before the underlying systemic disease has been diagnosed. With a view to the therapeutic consequences an early diagnosis of the underlying disease is advantageous. In cases of visual loss early diagnostic measures include invasive procedures, such as ultrasound-guided bronchoalveolar lavage and transbronchial biopsy, if nodular conjunctival or cutaneous manifestations which would confirm the diagnosis are not present...

AIMS: Immunoglobulin G4 (IgG4)-related disease is known to have diverse clinical manifestations. We report a case of IgG4-related ophthalmic disease misdiagnosed as intraocular tumor. METHODS: Case report. RESULTS: A 41-year-old man was referred to our department with a diagnosis of intraocular tumor, presumably choroidal melanoma. Although MR imaging was compatible with choroidal melanoma, he had been observed periodically without treatment because fundus findings were not typical of melanoma and visual function was preserved...

Uveal melanoma, which is the most common primary intraocular malignancy in adults, arises from melanocytes within the iris, ciliary body and choroid. The diagnosis is based principally on clinical examination of the tumor with biomicroscopy and indirect ophthalmoscopy and confirmed by diagnostic techniques such as ultrasonography, fundus fluorescein angiography and optical coherence tomography. The clinical diagnosis of posterior uveal melanomas can be made when the classical appearance of a pigmented dome-shaped mass is detected on dilated fundus exam...

BACKGROUND: Multiple choroidal granulomas are a rare presentation of tuberculosis. Choroidal granulomas in immunocompetent patients can pose difficulty in diagnosis as in most cases systemic examination may not reveal any evidence of tuberculosis. We report a case of bilateral multiple choroidal granulomas with systemic vasculitis-like features and disseminated tuberculosis in an immunocompetent patient without pulmonary involvement. FINDINGS: A 26-year-old male Indian patient presented with bilateral blurred vision and systemic illness with vasculitis-like features...

Ependymomas are gliomas that recapitulate normal ependymal cells. The epithelial membrane antigen (EMA) shows "dot-like" and "ring-like" staining patterns, highlighting "microlumens" or intracytoplasmic rosettes, a pathognomonic ultrastructural feature. NHERF1/EBP50, an adaptor protein localized at the apical plasma membrane of human epithelia, has been found to localize to these microlumens. We aimed to analyze the staining patterns of EMA and EBP50 in ependymomas and other tumors, and thereby compare their diagnostic utility...

PURPOSE: To describe clinical presentation and histopathological features of a nodulo-ulcerative variant of ocular surface squamous neoplasia (OSSN). METHODS: Retrospective study. RESULTS: Six patients were identified with a nodulo-ulcerative variant of OSSN. Mean age at presentation was 56 years. One patient was immunosuppressed because of human immunodeficiency virus infection. The initial misdiagnosis was necrotizing scleritis/sclerokeratitis (n = 4), intraepithelial neoplasia (n = 1), and chalazion (n = 1)...

In cats, lymphoma (lymphosarcoma) is the most common neoplasm affecting the spinal cord and the second most common intracranial tumour. Although lymphoma commonly develops in the spinal cord as a part of a multicentric process, a primary form may occur. Lymphoma can exhibit a wide range of morphological patterns, including intraparenchymal brain mass, lymphomatosis cerebri, intravascular lymphoma, lymphomatous choroiditis and meningitis, extradural, intradural-extramedullary or intramedullary lymphoma in the spinal cord, or neurolymphomatosis in the peripheral nerves...

PURPOSE: Mastocytosis is characterized by clonal mast cell proliferation with accumulation within various organs and uncontrolled activation with excessive mast cell mediator release. Ocular manifestations have rarely been published. We describe a 63-year-old man with bilateral exophthalmos that led to the diagnosis of systemic mastocytosis. CASE REPORT: A patient presented with bilateral eyelid edema with exophthalmos associated with binocular diplopia. Ophthalmologic examination showed bilateral axial, symmetrical, and painless exophthalmos with eyelid edema, and limitation in elevation of the right eye...

Biopsy involves the surgical removal of a tissue specimen for histopathologic evaluation. Most intraocular tumors are reliably diagnosed based on the clinical evaluation or with noninvasive diagnostic techniques. However, accurately diagnosing a small percentage of tumors can be challenging. A tissue biopsy is thus needed to establish a definitive diagnosis and plan the requisite treatment. From fine-needle aspiration biopsy (FNAB) to surgical excision, all tissue collection techniques have been studied in the literature...

INTRODUCTION: Endoscopic third ventriculostomy (ETV) is an established and effective treatment for obstructive hydrocephalus. In its most common application, surgeons plan their entry point and endoscope trajectory for the procedure based on anatomic landmarks, then free-handedly control the endoscope. We have introduced the Rosa robot assistance to our ETV procedure to stereotactically optimize endoscope trajectories, to reduce risk of traction on neural structures by the endoscope, and to provide a stable mechanical holder of the endoscope...
