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...

The authors describe a 39-year-old woman treated with fingolimod for relapsing-remitting multiple sclerosis for 2 years who then developed a bilateral conjunctival mucosa-associated lymphoid tissue lymphoma. Fingolimod treatment for multiple sclerosis has been associated with lymphoma in 3 previously reported cases. This is the first case of ocular adnexal lymphoma presumed to be due to fingolimod. Given that ophthalmologists regularly monitor many patients on fingolimod for fingolimod-associated macular edema and ophthalmic manifestations of multiple sclerosis, the authors hope to alert physicians of the possibility of ocular adnexal lymphoma in these patients...

Primary central nervous system lymphoma (PCNSL) is an uncommon variant of extranodal non-Hodgkin lymphoma, which involves the brain, leptomeninges, eyes, or spinal cord without evidence of systemic disease. In addition to a detailed history and physical examination, the evaluation of patients suspected of having a PCNSL should include a contrast-enhanced magnetic resonance imaging. Occassionaly, PCNSL shows peculiarities on magnetic resonance imaging, which delay the diagnosis and thus the start of treatment...

Lymphomas of the ocular adnexa and intraocular tissue include a wide range of lymphoproliferative neoplastic disorders. They are predominantly extranodal non-Hodgkin lymphomas (NHL). The World Health Organization (WHO) classification of lymphoid neoplasm and individual morphological, immunophenotypical, and molecular genetic features, indicate that they may be divided into B-cell (approximately 80 % of all NHL) and T-cell lymphomas (approximately 10-20 % of all NHL). The most common forms of ocular NHL are extranodal marginal zone lymphoma (EMZL) of the mucosa-associated lymphoid tissue (MALT-type), follicular lymphoma (FL), diffuse large B-cell lymphoma, and mantel cell lymphoma...

This study analysed incidence, patient outcome, immunophenotype and prognostic factors of histological transformation (HT) from extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) to diffuse large B-cell lymphoma (DLBCL) in 467 patients (median age, 61 years). The primary sites of MALT lymphoma were the stomach (43%), ocular adnexa (25%), lung (8%), systemic (8%) and other tissues (16%). HT occurred in 8% of MALT lymphomas. Risk of HT by 15 years was 5%: 4% in limited-stage diseases (n = 385) and 16% in advanced-stage diseases (n = 56) (P = 0·02)...

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) invariably arises from a background of chronic microbial infection and/or autoimmune disorder at diverse mucosal sites. The prolonged chronic infection and/or autoimmunity generate active immune and inflammatory responses that provide a setting for evolution and development of autoreactive B-cells, their expansion and eventual malignant transformation following acquisition of genetic changes. The immune responses also play a critical role in sustaining the growth and survival of the transformed cells as shown by complete regression of a high proportion of MALT lymphoma of the stomach, ocular adnexa and skin following anti-microbial treatment...
