Purpose: To report a case of corneal infiltration and xanthoma formation in mycosis fungoides (cutaneous T-cell lymphoma). Observations: A middle aged Japanese man with mycosis fungoides (MF) involving the face was referred to Ophthalmology for evaluation of unilateral, painless conjunctival injection. Biopsy of the conjunctiva revealed a malignant T cell population consistent with MF tumor invasion. Years later, he returned following several episodes of infectious keratitis with a painless, yellow, rapidly forming mass in the left eye over two weeks...

Purpose: To report a rare case of primary orbital natural killer (NK)/T-cell lymphoma without nasal lesions but with cerebrospinal fluid involvement. Observations: A 73-year-old woman was referred to the uveitis clinic with suspected unilateral acute uveitis in her right eye and a right orbital tumor. Epstein-Barr virus DNA was detected in the aqueous humor in her right eye, and orbital biopsy revealed the presence of extranodal NK/T-cell lymphoma (ENKTL), nasal type...

Both-side synchronous involvement has been reported to account for 7-24% of ocular adnexal marginal zone lymphoma (OAML). We conducted a retrospective analysis to identify the clinical features and treatment outcomes of synchronous bilateral OAML (SB-OAML) by treatment modality. We analyzed patients with a histologic diagnosis of SB-OAML, excluding metachronous bilateral involved OAML. We enrolled a total of 95 patients for this analysis, 36 males and 59 females; the median patient age was 42 years (range 16-77 years)...

Hemophagocytic syndrome (HPS) is a clinicopathological entity characterized by histiocytic proliferation, with marked hemophagocytosis in the reticuloendothelial organs. HPS caused by lymphoma is termed lymphoma-associated hemophagocytic syndrome (LAHS), and there are few reports on canine and feline LAHS. The objective of this study was to examine the clinical, diagnostic, and clinicopathologic features of LAHS in six dogs. The diagnostic criteria of LAHS consisted of lymphoma, bicytopenia or pancytopenia in the blood, and increased hemophagocytosis in the reticuloendothelial organs...

This study sought to explore the prognostic factors in a large retrospective cohort of patients with B-cell primary ocular lymphoma (POL) from the Surveillance, Epidemiology, and End Results database. There were 2778 patients with B-cell POL whose complete clinical information was listed in the Surveillance, Epidemiology, and End Results database between 1997 and 2014. The epidemiology, therapeutic measures, and clinical characteristics were listed as descriptive statistics. Survival analysis was conducted by univariate and multivariable Cox regression models...

Hematological diseases can lead to ocular manifestations. Retinal manifestation occurs in patients with anemia, leukemia, lymphoma, myeloproliferative and myelodysplastic syndromes. It is not uncommon for the ocular findings to be the first manifestation of the systemic disease. In these patients the correct diagnosis can be difficult because as a rule the retinal involvement is unspecific. In cases of unexplained retinal changes with hemorrhage and cotton wool spots, an underlying hematological disease should be suspected and the appropriate diagnostics should be recommended...

Sjogren's syndrome (SS) is an autoimmune disease, among the most common ones, that targets mainly the exocrine glands as well as extra-glandular epithelial tissues. Their lymphocytic infiltration leads to manifestations from other organs (e.g., kidneys, lungs, liver, or thyroid), apart from sicca symptoms (xerostomia and keratoconjunctivitis). SS is more prevalent in women than in men (9:1). Moreover, p.SS patients are in increased risk to develop lymphoma. Certain autoantibodies (e.g., antibodies against ribonucleoprotein autoantigens Ro-SSA and La-SSB) are ultimate hallmarks for the disease...

Purpose: We present the first reported case of Waldenstrom macroglobulinemia in the right superior rectus causing diplopia. Observations: A 72-year-old man with a 6-month history of untreated asymptomatic Waldenstrom macroglobulinemia presented with 2 years of diagonal binocular diplopia that was previously thought to be due to ocular myasthenia gravis. Examination showed mild right proptosis and right hypotropia, and MRI revealed a focal lesion of the right superior rectus muscle...

Background: To describe the recent diagnostic and treatment options for the most predominant form of primary vitreoretinal lymphoma (PVRL), namely diffuse large B cell lymphoma. This is mainly based on the experience at the Mayo Clinic as well as a partial review of the literature. MYD88 L265P mutation is seen in about 80% of cases; therefore, a polymerase chain reaction for this mutation helps in making the diagnosis that has been notoriously difficult to make. Local therapy using intravitreal methotrexate and rituximab has been very helpful in the treatment of the local disease...

We describe a rare case of isolated extraocular muscle ocular adnexal lymphoma of a middle-aged female who presented with redness in the left eye associated with progressive proptosis over one year. Magnetic resonance imaging of the orbit indicated isolated enlargement of the left superior oblique (SO) muscle with an apparent diffusion coefficient (ADC) of (0.77 ± 0.11 × 10-3  mm2 /s). Histopathology with immunohistochemical staining of the incisional biopsy from the SO muscle belly confirmed the diagnosis of extranodal marginal zone B cell lymphoma...

Background & objectives: Ocular and adnexal tumours are important causes of morbidity in India and globally. Immunohistochemistry (IHC) is a vital molecular pathology tool, which helps to diagnose a tumour with more accuracy. The present study was undertaken to document the profile of ocular and adnexal tumour with IHC at a tertiary eye care center in Northeast India. Methods: This was a prospective and laboratory-based study. Histopathological and IHC study of the ocular and adnexal tumour was carried out from 2012 to 2014...

Primary uveal lymphoma is a type of intra-ocular lymphoma. Unlike the intra-ocular lymphomas involving the retina and vitreous, primary uveal lymphoma generally has a low-grade nature and an indolent clinical course. It is a relatively rare condition, and the diagnosis can be challenging. We present a rare case of primary uveal lymphoma involving the choroid, ciliary body, iris and conjunctiva that was successfully treated with radiotherapy and achieved full remission.

The aim of this work was to determine whether conjugation of cultivated choroidal melanoma and Burkitt's lymphoma cells with gold nanoparticles (GNPs) is beneficial for these series of ocular cancer patients. GNPs are radiosensitizers and can sensitize tumors to radiotherapy.This application has been examined in several tumor types, but not in choroidal melanoma. This study shows the results of in vitro study on the choroidal melanoma and also Burkitt's lymphoma cells in the presence of GNPs during continuous gamma irradiation...

AIMS: To evaluate the clinical characteristics and treatment outcomes of natural killer/T-cell lymphoma (NKTL) involving the ocular adnexa. METHODS: Retrospective, comparative, observational case series. A total of 350 patients with NKTL, including 27 patients with NKTL involving the ocular adnexa from 1999 to 2016. The patients were grouped into two groups: group 1 comprised patients presenting with ophthalmic symptoms, and group 2 comprised patients presenting with symptoms from other organs but subsequently developed ophthalmic involvement...

The purpose of this study was to investigate the efficacy of F-fluoro-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for evaluating the ocular adnexal lymphoma treatment responses.We retrospectively reviewed data for 9 histologically confirmed cases of malignant lymphoma. All patients had at least one ocular adnexal tumor site and underwent FDG PET/CT before and after treatment. Patients' histological disease subtypes included diffuse large B-cell lymphoma (n = 3), mucosa-associated lymphoid tissue lymphoma (n = 2), follicular lymphoma (n = 1), NK/T-cell lymphoma (n = 1), lymphoplasmacytic lymphoma (n = 1), and Hodgkin lymphoma (n = 1)...

Radiation therapy is an effective treatment for primary orbital lymphomas. Lens shielding with electrons can reduce the risk of high-grade cataracts in patients undergoing treatment for superficial tumors. This work evaluates the dosimetric effects of a suspended eye shield, placement of bolus, and varying electron energies. Film (GafChromic EBT3) dosimetry and relative output factors were measured for 6, 8, and 10 MeV electron energies. A customized 5-cm diameter circle electron orbital cutout was constructed for a 6 × 6-cm applicator with a suspended lens shield (8-mm diameter Cerrobend cylinder, 2...
