The aim of this study was to investigate 10 cases of bovine ocular squamous cell carcinoma (OSCC) diagnosed in Holstein or Holstein-crosses cows
B cell monoclonal gene rearrangements have been reported in several cases of primary intraocular lymphoma and primary central nervous system lymphomas. Such molecular analysis has been performed on only one case of a primary testicular and a metastatic intraocular lymphoma. However, the gene rearrangements differed at the two sites. We present a case in which B cell monoclonality was found in an intraocular lymphoma and a primary breast lymphoma. Intraocular non-Hodgkins lymphomas are uncommon malignant tumours derived from two types of lymphomas; a primary central nervous system lymphoma (PCNSL) and a systemic lymphoma. Compared with primary intraocular lymphomas (PIOLs), the prevalence of metastatic systemic lymphomas is much lower.1 2 The diagnosis of … ...
Abstract: : Purpose: Primary intraocular lymphoma, a form of primary central nervous system lymphoma, is a diffuse large B-cell lymphoma showing immunoglobulin heavy chain (IgH) gene rearrangements. Its pathogenesis remains unknown but may be linked to certain infectious agents. Our purpose was to report a small case series of severe toxoplasmic retinochoroiditis and vitritis in which 2 of 3 patients showed lymphoma cells in their vitreous specimen Methods: Among the 654 uveitis patients seen in the Uveitis Clinic at La Source Eye Center since January1995, 67 patients (10.2%) were diagnosed with ocular toxoplasmosis. Three patients with severe evolving inflammation despite maximal therapy underwent vitrectomy because of persistent retinitis and/or vitritis. Vitreous specimen were used to detect the presence of T. gondii DNA by PCR and to perform screening for lymphoma cells by microdissection and PCR demonstration of gene rearrangement of immunoglobulin heavy chains. The lymphoma cells were ...
Intraocular lymphoma is a rare malignant form of eye cancer. Intraocular lymphoma may affect the eye secondarily from a metastasis from a non-ocular tumor or may arise within the eye primarily (primary intraocular lymphoma, PIOL). PIOL is a subset of primary central nervous system lymphoma (PCNSL). PCNSL (and PIOL) are most commonly a diffuse large B-cell immunohistologic subtype of non-Hodgkins lymphoma according to the World Health Organization (WHO) classification of lymphomas. The most common symptoms of PIOL include blurred or decreased vision due to tumor cells in the vitreous. Most cases of PIOL eventuate to central nervous system involvement (PCNSL) while only 20% of PCNSL lead to intraocular (PIOL) involvement. PIOL and PCNSL remain enigmas because both structures are immunologically privileged sites (the brain sits behind the blood-brain barrier and the retina sits behind the blood-retinal barrier) and so do not normally have immune cells trafficking through these structures. What is ...
Similar to other series, the most common lymphoma subtype in our collection of ocular adnexal lymphomas was the EMZL (67% of our patients). Approximately one third of these cases had been previously diagnosed as RLH. A revision of the original diagnosis could be made, however, on the basis of the morphology and the immunophenotype of the infiltrating cells, in particular, the demonstration of a monotypical expression of either the light or heavy chains of the immunoglobulin molecules. This relatively high proportion of lymphoma cases with the former diagnosis RLH exemplifies the difficulty in distinguishing RLH and many EMZL on the basis of conventional histology. EMZL was only described as an entity in 1983 by Isaacson and co-workers, and, therefore, it can be assumed that many EMZL of the ocular adnexa (and other sites) were misdiagnosed as RLH before this description. It would also explain the relatively high incidence of reported progression of RLH of the ocular adnexa into systemic lymphoma ...
This program explains eye cancers. Eye cancers are also known ocular cancers. The program includes the following sections: anatomy of the eye, what is eye cancer, what causes eye cancer and who is at risk, what are the symptoms of eye cancer, how is eye cancer diagnosed, what are the stages of cancer, how is eye cancer treated and what type of supportive care is available for people with eye cancer.
80 Year Old Female Patient came in 1 year ago with a retinal whitening in her eye and uveitis. Her uveitis work-up was negative, and because of the retinal whitening and the uveitis, I was concerned about a possible occult acute retinal necrosis case. I put her on Valtrex, but the eyes did not get any better and the retinal whitening continued. Then later, I became concerned about a possible primary ocular lymphoma. She had an extensive cancer evaluation that was all negative. She has had MRI scans and ultimately I did a vitrectomy on both eyes. I did the right eye on May 30th of 2012 and flow cytometry and cytology was negative. That eye cleared nicely, but then, because of increasing uveitis in the left eye, I did a vitrectomy in the left eye on December 19th of 2012. That sample I sent to the lab in Miami and that result was similarly negative. I am going to send you all of the results so you have them when you see her. At this point, it has been unclear whether she had uveitis, infectious ...
Tumors inside the eye are referred to as ocular tumors. These are collections of cells that grow and multiply abnormally and form a mass. Ocular tumors can be benign or malignant. The most common type of ocular tumor in adults is metastatic - meaning that it spreads from another part of the body - such as the lung, breast, and prostate, among others. Another common type of ocular tumor is a malignant melanoma. These can begin as a small "mole" or "birthmark" in the eye, called a choroidal nevus. Often times, your general ophthalmologist or optometrist may find these asymptomatic lesions during a routine exam. These should be carefully monitored for growth by your retina specialist.. Treatment for ocular tumors typically includes radiation and chemotherapy. In severe cases, enucleation of the eye may be required. Radiation can be either in the form of proton beam radiation or placement of radiation plaque on the eye. Both types of radiation therapy can be very effective in eliminating a malignant ...

CYPEL, Marcela; BELFORT JR., Rubens; MORAES, Nilva and MUCCIOLI, Cristina. Primary intraocular B-cell lymphoma: case report. Arq. Bras. Oftalmol. [online]. 2007, vol.70, n.4, pp.709-712. ISSN 0004-2749. http://dx.doi.org/10.1590/S0004-27492007000400026.. Ocular non-Hodgkins lymphoma is a rare condition that can involve the retina, the vitreous and the optic nerve. It can occur alone or can be associated with lymphoma of the central nervous system and a frequent manifestation is a posterior uveitis of difficult treatment. This kind of ocular tumor is difficult and a challenge to diagnosis. We describe a case of non-Hodgkins intraocular B-cell lymphoma in a 47-year-old woman who had a posterior uveitis as the first manifestation. We emphasize the importance of a careful investigation and of the general clinical examination since this is the most common type in the eye. We expect to call the attention to this disease that many times appears in an unspecific form with unspecific ...
Published July 2014. ISBN: 978-1-78084-426-8. The past five years have seen the most significant advances in our understanding of ocular melanoma since its first recognition in the 1500s.

Eighteen people have been diagnosed with the same type of rare eye cancer - including three university friends - leading researchers to push for funding to find connections, a cause, and a cure.. The melanoma, a type of cancer that develops in melanin - the pigment that gives skin its colour, only occurs in about six out of one million people but at least 18 people have been diagnosed with ocular melanoma recently - curiously all have ties to one or both of the communities in Huntersville, North Carolina or Auburn, Alabama.. To add to the mystery, three friends who met at Auburn University: Juleigh Green, Allison Allred and Ashley McCrary are all being treated for the disease. According to CBS, one of the leading doctors on the case is Marlana Orloff, an oncologist at Thomas Jefferson University in Philadelphia. "Most people dont know anyone with this disease," Ms Orloff said, adding: "We said, Okay, these girls were in this location, they were all definitively diagnosed with this very rare ...
For CDR3 size polymorphism analysis we used the Immunoscope software package. 23 Immunoscope analysis couples fluorescence PCR and software analysis and allows the direct and accurate sizing of a clonal population of T or B cells within a polyclonal milieu. Peripheral blood mononuclear cells (PBMCs) were prepared by centrifugation on single-density gradient (Ficoll Hypaque; Pharmacia, Upsala, Sweden) and processed for Immunoscope analysis, as previously described. 25 An Epstein-Barr virus (EBV)-transformed human B lymphoblastoid cell line (BLCL) was established in the laboratory and maintained as previously described. 26 The vitreous humor was obtained after vitrectomy. Approximately 200 μL of vitreous humor was diluted in a saline solution to a final volume of 1 mL, and the samples were centrifuged immediately (910g for 10 minutes at 4°C). Previous morphologic studies revealed that such amounts of vitreous humor obtained from PIOL patients contain, on average, 1000 cells (Merle-Beral H, ...

As many of you know, Cara was diagnosed with Ocular Melanoma, a rare form of eye cancer in May of 2014. While hers was detected early, putting her in the highest survival rate group, this type of cancer is particularly lethal. If OM spreads beyond the eye, it is metastatic and approximately 50% of OM patients go on to develop metastatic disease. 80-90% of the time, the liver is the first site of this metastatic disease given the hematologic nature of OM. In other words, OM spreads via the blood and not via the lymphatic system such as with cutaneous melanoma, and the liver is thus affected. In general, prognosis is poor after an ocular tumor has metastasized. Without treatment, the median survival time is 2 to 8 months. Standard chemotherapies, overall, have not proven to be effective in treatment of metastatic OM. Today, there are no approved treatments for OM once it has spread. THIS IS WHERE YOU CAN HELP MAKE A DIFFERENCE. Many new and promising clinical trials are being offered and more

Retinoblastoma information, including signs and symptoms, types of eye cancer, diagnosing retinoblastoma, the red reflex test and treatment options.
Retinoblastoma treatment typically requires the cooperation of an ophthalmic oncologist, pediatric oncologist, and radiation therapist. Over the last 30 years, treatment has evolved from simple enucleation (removal of the eye), to eye-sparing radiotherapy, and more recently to chemotherapy-based multi-modality therapy (for selected cases). Intra-arterial chemotherapy (IAC) has recently been investigated to save eyes, vision and spare the child from systemic chemotherapy.. Though retinoblastoma has been cured by external beam irradiation, investigators have found that radiation may cause an increase in the risk of developing second cancers later in life.. Protocols are currently being evaluated to use chemotherapy to shrink the retinoblastoma in order to treat them with laser therapy, freezing therapy (cryotherapy), and local "plaque" radiation. Where applicable, these techniques are thought to be safer than external beam irradiation for retinoblastoma. Intra-arterial chemotherapy is a newer ...

Audio available Their findings are available online in the journal Clinical Cancer Research.. J. William Harbour, MD. A look at aggressive uveal melanoma cells under the microscope. These tumor calls carry the so-called "class 2 signature," meaning they are likely to be aggressive and spread outside of the eye.. Uveal melanoma, the second most common form of melanoma, can be very aggressive and spread, or metastasize, from the eye to other organs, especially the liver.. "Melanoma in general, and uveal melanoma in particular, is notoriously difficult to treat once it has metastasized and grown in a distant organ," says principal investigator J. William Harbour, MD. "We previously identified an aggressive class 2 molecular type of uveal melanoma that, in most cases, already has metastasized by the time the eye cancer is diagnosed, even though imaging the body cant detect it yet. This microscopic amount of cancer can remain dormant in the liver and elsewhere for several years before it begins to ...

Initially, Harbours group identified differences in approximately 1,000 genes between class 1 and class 2 tumors, but they whittled down that number, hoping to develop a simple test that could be used easily by ophthalmologists. Eventually, they settled on about a dozen genes that could be evaluated in tumor samples collected with a needle biopsy.. "We went through a number of sophisticated algorithms and validations, and we came up with a group of 12 genes," he says. "We also included three more genes that dont change whether they are in tumor tissue or healthy tissue. Those genes act as our controls in this prognostic test.". Testing tumor tissue from his own ocular melanoma patients at the Alvin J. Siteman Cancer Center at Barnes-Jewish Hospital and Washington University in St. Louis, Harbour found that the gene expression profile test was very good at identifying the two classes of tumors. Then he started recruiting other centers to test the method, too.. "It doesnt make for a good test ...
