Deep learning-based intratumoral and peritumoral features for differentiating ocular adnexal lymphoma and idiopathic orbital inflammation.

Objectives: To evaluate the value of deep-learning-based intratumoral and peritumoral features for differentiating ocular adnexal lymphoma (OAL) and idiopathic orbital inflammation (IOI).

Methods: Nighty-seven patients with histopathologically confirmed OAL (n = 43) and IOI (n = 54) were randomly divided into training (n = 79) and test (n = 18) groups. DL-based intratumoral and peritumoral features were extracted to characterize the differences in heterogeneity and tissue invasion between different lesions, respectively.

Endoretinal biopsy outcomes in suspected vitreoretinal lymphoma after inconclusive vitreous cytology.

Methods: Retrospective case series including all consecutive patients who underwent endoretinal biopsies in a tertiary care center, Hospital Clinic of Barcelona (Spain), between 2014 and 2020.

Results: A total of 5 patients were included in this study.

Inflammatory Myofibroblastic Tumor of the Orbit: A Case Series and Literature Review.

Purpose: Orbital inflammatory myofibroblastic tumors (IMTs) are a rare tumor with intermediate biological potential. We analyzed a series of orbital IMTs to determine their unique features.

Methods: Records from patients with pathologically confirmed IMT at Beijing Tongren Hospital, Capital Medical University, between January 2004 and August 2022, were reviewed for their ocular presentation and treatment outcomes.

A Diagnostic Approach in Large B-Cell Lymphomas According to the Fifth World Health Organization and International Consensus Classifications and a Practical Algorithm in Routine Practice.

In this article, we provide a review of large B-cell lymphomas (LBCLs), comparing the recently published fifth edition of the WHO classification and the International Consensus Classification (ICC) on hematolymphoid tumors. We focus on updates in the classification of LBCL, an heterogeneous group of malignancies with varying clinical behaviors and different pathological and molecular features, providing a comparison between the two classifications. Besides the well-recognized diagnostic role of clinical, morphological and immunohistochemical data, both classifications recognize the ever-growing impact of molecular data in the diagnostic work-up of some entities.

Pleural Marginal Zone Lymphoma Masquerading as Metastatic Adenocarcinoma of the Lung.

Extranodal marginal zone lymphoma (EMZL) is a rare subtype of non-Hodgkin's lymphoma characterized by the malignant transformation of lymphoid tissue at sites affected by chronic inflammation. Pleural marginal zone lymphoma (PMZL) is an infrequent manifestation of this condition. We report a case of PMZL co-occurring with primary lung adenocarcinoma.

The clinical phenotype of isolated ocular or oral dryness in Sjögren's disease.

Objectives: To assess if isolated mouth or eye dryness constitutes distinct clinical phenotypes in Sjögren's disease (SjD).

Methods: We analysed 1765 patients meeting the 2016 ACR-EULAR SjD criteria, followed up at four centres in Greece and Italy (Universities of Pisa, Italy, and Athens, Harokopion, and Ioannina, Greece). Patients with isolated mouth or eye dryness were identified and matched 1:2 with those experiencing both symptoms, according to age at SjD diagnosis, gender, and disease duration.

Candy Cane Hypopyon Secondary to Intraocular Mantle Cell Lymphoma: A Case Report.

Introduction: Bilateral hemorrhagic hypopyon, also known as candy cane hypopyon, is an extremely rare presentation which we report as a unique case in association with intraocular mantle cell lymphoma (MCL).

Case Presentation: A 63-year-old white male presented with a 3-week history of conjunctival injection OS that was unresponsive to erythromycin ointment and topical steroids, in the setting of recently discovered diffuse lymphadenopathy and malaise. On presentation, he was found to have bilateral hemorrhagic hypopyon.

Retromode imaging in vitreoretinal lymphoma.

Purpose: The purpose of this study was to evaluate Retromode (Nidek Co., Gamagori, Japan) as an adjunct diagnostic tool in vitreoretinal lymphoma (VRL). By integrating Retromode findings with multimodal imaging, we aimed to enhance lesion detection of VRL lesions in the retina.

A Rare Case of Combined Direct Retinal Involvement and Suspected Bing-Neel Syndrome in a Patient With Waldenstrom's Macroglobulinemia.

A 75-year-old male with a history of Waldenström macroglobulinemia (WM), diagnosed in 2022, presented with several months of progressive blurred vision and floaters in his right eye, impairing his ability to drive, particularly at night. The ophthalmologic evaluation revealed vitreous haemorrhage and sub-retinal pigment epithelial lesions in the superonasal and inferonasal quadrants of the right eye. A pars plana vitrectomy with vitreous biopsy was performed, which was consistent with ocular involvement by WM.

Marginal zone lymphoma of extranodal sites: A review with an emphasis on diagnostic pitfalls and differential diagnosis with reactive conditions.

Marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) represents 8% of all B-cell lymphomas and it is the most common small B-cell lymphoma arising at extranodal sites. The gold-standard test to establish a diagnosis of MALT lymphoma remains histopathologic analysis with the aid of immunohistochemistry (IHC) and/or flow cytometry immunophenotypic analysis. MALT lymphoma represents a progression from a persistent chronic inflammatory process, and therefore distinguishing MALT lymphoma from chronic inflammation by histopathology may be challenging in some cases.

Mycophenolate Mofetil-Induced Lymphoproliferative Disorder in a Young Adult With Chronic Posterior Uveitis.

To present a case of a young adult with bilateral chronic posterior uveitis resulting from Vogt-Koyanagi-Harada (VKH) disease treated with mycophenolate mofetil who subsequently developed vitreoretinal lymphoma in the right eye. A case and its findings were analyzed. A 34-year-old Hispanic woman presented with an 8-year history of chronic recurrent posterior uveitis in both eyes secondary to VKH disease.

Evaluation of a novel anti-oxidant Ubiquinol acetate (EnQ10) for its safety by methods.

Background: As an active form of Coenzyme Q10 (CoQ10), Ubiquinol acetate (EnQ10) is a newly developed, chemically stable, and physiologically active novel antioxidant. In addition to its anti-oxidant properties, CoQ10 is a useful cosmetic agent for human skin.

Purpose: This study goal was to examine the safety of EnQ10 using models instead of animal models.

The Role of Radiotherapy in Indolent Ocular Adnexal and Orbital Lymphomas.

Background: This study evaluates the oncological outcomes and toxicities of indolent ocular adnexal and orbital lymphomas (OOLs) treated with radiotherapy (RT) ± systemic therapy.

Methods: A retrospective analysis of 44 patients with indolent OOLs treated with RT was conducted.

Results: Most patients (87%) had early-stage disease.

Living histopathology - interrogation of ocular tissues by light: a celebration of the slit-lamp and a repertoire of clinical techniques.

The evolution of the slit-lamp microscope has enabled ophthalmologists to examine the transparent tissues of the eye with histological detail. This paper considers the history and optics of the slit-lamp. Optical sectioning and retro-illumination are discussed; particularly, effective placement of the reflected light beam.

PSAT1 is upregulated by METTL3 to attenuate high glucose-induced retinal pigment epithelial cell apoptosis and oxidative stress.

Background: Diabetic retinopathy (DR) is a major ocular complication of diabetes mellitus, and a significant cause of visual impairment and blindness in adults. Phosphoserine aminotransferase 1 (PSAT1) is an enzyme participating in serine synthesis, which might improve insulin signaling and insulin sensitivity. Furthermore, it has been reported that the m6A methylation in mRNA controls gene expression under many physiological and pathological conditions.
