Marek's disease (MD) is a major cause of mortality in backyard chickens. The diagnosis of MD is complex, however, and knowledge of Marek's disease virus (MDV) in spontaneous field cases such as in backyard chickens is largely unknown. In this study, 40 backyard chickens with a presumptive MD diagnosis based on histologic lymphoid infiltrations in peripheral nerves with and without lymphomas were investigated. Twenty-eight of the birds were submitted to the diagnostic laboratory for disease explorations, and 12 chickens were from a flock in which some members demonstrated anisocoria and pupil irregularities compatible with ocular MD...

REVIEW
Frederik Holm Svendsen, Steffen Heegaard
Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases--14%) and diffuse large B-cell lymphoma (18 cases--9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases--13%), extranodal NK/T-cell, nasal type lymphoma (12 cases--6%) and primary cutaneous anaplastic large cell lymphoma (12 cases--6%)...

Baraitser-Winter malformation syndrome (BWMS), Fryns-Aftimos syndrome (FA), and craniofrontofacial syndromes (CFFs) have all been recently proposed to be part of the same phenotypic spectrum of Baraitser-Winter cerebrofrontofacial syndrome (BWCFF), which is characterized by facial dysmorphism, ocular coloboma, brain malformations, and intellectual disabilities. In addition to that, the recent discovery of missense mutations in one of the two ubiquitously expressed cytoplasmic β- and γ-acting-encoding genes ACTB (7p22...

Infectious agents have been identified as a major cause of specific types of human cancers worldwide. Several microorganisms have been identified as potential aggravators of ocular adnexal neoplasms; however, given the rarity of these neoplasms, large epidemiological studies are difficult to coordinate. This study aimed to conduct an exhaustive search for pathogenic DNA in lymphoproliferative disorders (LPD) of the ocular adnexa in a total of 70 patients who were diagnosed with LPD of the ocular adnexa between 2008 and 2013...

While Primary Ocular Adnexal MALT Lymphoma (POAML) is the most common orbital tumor, there are large gaps in knowledge of its natural history. We conducted a retrospective analysis of the largest reported cohort, consisting of 182 patients with POAML, diagnosed or treated at our institution to analyze long-term outcome, response to treatment, incidence and localization of relapse and transformation. The majority of patients (80%) presented with stage I disease. Overall, 84% of treated patients achieved a complete response after first-line therapy...

A 41-year-old man was diagnosed with immunoglobulin G4-related disease (IgG4-RD) in both eyelids 4 years ago and exhibited good response to steroid therapy. However, rapid swelling of the right eyelid lesion was recently observed. As IgG4-RD progression was suspected, biopsy was performed. Although the histology was consistent with IgG4-RD, the infiltrating large atypical lymphoid cells showed immunoglobulin light-chain restriction and IgH gene rearrangement. Consequently, he was diagnosed with extranodal marginal zone lymphoma with abundant IgG4-positive cells...

Extranodal natural killer/T-cell lymphoma (ENK/TCL) is most often in the nose or the nasopharynx but can present elsewhere. We report a rare case of ENK/TCL that presented as swelling of an upper eyelid without ocular involvement. A 76-year-old man visited our hospital with a swollen lesion of the left upper eyelid which had appeared 2 months earlier. A biopsy of the upper eyelid revealed slight perivascular and periadnexal infiltration of mononuclear cells with dermal edema. Treatment with oral prednisolone at a dosage of 20 mg/day decreased the eyelid swelling...

We report a rare case of diffuse large B-cell lymphoma (DLBCL) of the lacrimal sac in a 50-year-old male. The incidence of primary ocular lymphoma is low and it is considered a rare disease. Moreover, reports of ocular DLBCL are uncommon and the disease remains poorly characterized. Our patient presented for management of osteomyelitis and was incidentally found to have a painless swelling and cyst around his right eye. A PET/CT scan revealed hypermetabolic activity within the lacrimal sac and a subsequent excisional biopsy of the mass yielded histopathology consistent with DLBCL...

BACKGROUND: The most common type of ocular lymphoma is non-Hodgkin lymphoma (NHL), categorized into two groups: indolent (slow growing) and aggressive (rapid growing). Differentiating benign reactive lymphoid hyperplasia (RLH) from malignant ocular adnexal lymphoma (OAL) is challenging. Histopathology, immunohistochemistry (IHC) and ow cytometry have been used as diagnostic tools in such cases. MATERIALS AND METHODS: In this retrospective case series, from 2002 to 2013 at Farabi Eye Center, 110 patients with ocular lymphoproliferative disease were enrolled...

We describe a patient with oculomotor nerve palsy due to secondary orbital infiltration from the primary malignant lymphoma of the cheek. The patient was a 78-year-old female who had non-Hodgkin lymphoma (diffuse large B cell lymphoma [DLBCL]) of the cheek. The patient received chemotherapy and local radiation therapy. The combined treatment brought about complete remission. About 6 months after the last treatment the patient began to have left blepharoptosis and impaired vision. Findings from ophthalmological and neurosurgical examinations suggested no intraorbital or intracranial lesions...

PURPOSE: Brn3b is a class IV POU domain transcription factor that plays an important role in the development of retinal ganglion cells (RGCs), RGC survival, and particularly axon growth and pathfinding. Our previous study demonstrated that recombinant adenoassociated virus serotype 2 (rAAV-2)-mediated overexpression of Brn3b in RGCs promoted neuroprotection in a rodent model of glaucoma. However, the mechanisms underlying neuroprotection of RGCs in rats overexpressing Brn3b in animal models of glaucoma remain largely unknown...

Pathological alterations to the retinal pigment epithelium underlie several eye diseases, which lead to visual impairment and even blindness. Exposure to ultraviolet (UV) radiation is associated with some skin and ocular pathologies; UV radiation may induce DNA breakdown and cause cellular damage through the production of reactive oxygen species (ROS), thus leading to programmed cell death. The present study aimed to investigate the production of ROS and the gene expression levels of anti‑ and proapoptotic proteins [B‑cell lymphoma 2 (Bcl‑2), Bcl‑2‑associated X protein (Bax) and caspase‑3] in human retinal pigment epithelial cells (ARPE‑19) treated with UV‑A for 5 h consecutively...

The pathogenesis of ocular adnexal marginal zone lymphomas of mucosa-associated lymphatic tissue-type (OAML) is still poorly understood. We analyzed 63 cases of such lymphomas for non-synonymous mutations in 24 candidate genes by amplicon sequencing. We validated frequent mutations in the NF-κB regulators MYD88, TNFAIP3 and TNIP1 in OAML, but also identified recurrent mutations in several additional components of the NF-κB pathway, including BCL10 and NFKBIA. Overall, 60% of cases had mutations in at least one component of NF-κB signaling, pointing to a central role of its genetic deregulation in OAML pathogenesis...
