Introduction And Importance: Orbital lymphomas, are extranodal lymphomas primarily involving the ocular adnexa, which includes conjunctiva, eyelids, eyelashes, eyebrows, lacrimal glands, retro-orbital soft tissues, and the extraocular muscles. Ocular adnexal lymphomas can be primary or secondary. This case is important because there are few case reports in the world, and it is among the first case to be reported from Ethiopia.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.

Tumor whole-cell vaccines are designed to introduce a wide range of tumor-associated antigens into the body to counteract the immunosuppression caused by tumors. In cases of lymphoma of which the specific antigen is not yet determined, the tumor whole-cell vaccine offers distinct advantages. However, there is still a lack of research on an effective preparation method for the lymphoma whole-cell vaccine.

Introduction: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of non-Hodgkin lymphoma with a good prognosis, but the optimal treatment for relapsed/refractory (R/R) SPTCL has been rarely discussed.
Methods: This study aims to compare the efficacy of conventional chemotherapy and chemo-free immunomodulatory regimen for R/R SPTCL. We retrospectively reviewed the patients with first relapse or primary refractory SPTCL between September 1997 and October 2020.
Rituximab-IgG2 is a phagocytic enhancer in antibody-based immunotherapy of B-cell lymphoma by altering CD47 expression.

Antibody-dependent cellular phagocytosis (ADCP) by monocytes and macrophages contributes significantly to the efficacy of many therapeutic monoclonal antibodies (mAbs), including anti-CD20 rituximab (RTX) targeting CD20 B-cell non-Hodgkin lymphomas (NHL). However, ADCP is constrained by various immune checkpoints, notably the anti-phagocytic CD47 molecule, necessitating strategies to overcome this resistance. We have previously shown that the IgG2 isotype of RTX induces CD20-mediated apoptosis in B-cell lymphoma cells and, when combined with RTX-IgG1 or RTX-IgG3 mAbs, can significantly enhance Fc receptor-mediated phagocytosis.
