Objective: we present a 14 year retrospective histopathological study of 92 cases of adult lymphomas in Lagos. The aim is to document the histologic types, age and sex distribution.
Materials And Method: The materials consisted of slides and paraffin embedded blocks of all cases of lymphoma in adults above the age of 16 years seen between 1991 and 2004 at the Morbid Anatomy Department of Lagos University Teaching Hospital Idi-Araba Lagos.
Results: Of ninety two cases of lymphoma studied, male and female patients accounted for 59(64%) and 33(36%) cases respectively, giving a M: F ratio of 1.8:1. The most frequently biopsied site is the cervical lymph node. Non-Hodgkin's lymphoma (NHL) which accounted for 60 cases occurred most frequently in the 46-55 years age group and gives a male: female ratio of 2:1. Intermediate grade, high grade and low grade variants of NHLs accounted for 39%, 34% and 27% respectively. Hodgkin's lymphoma mostly affected patients of younger age group, 25-35 years with a M:F ratio of 1.7:1. Mixed cellularity 17 (55%) was the commonest subtype of Hodgkin's lymphoma.
Conclusion: Non-Hodgkin's lymphoma is commoner than Hodgkin's lymphoma. The age and sex distribution agrees with reports from other parts of Nigeria and Africa with minimal variations.

Results From First-in-Human Phase I Study of a Novel CD19-1XX Chimeric Antigen Receptor With Calibrated Signaling in Large B-Cell Lymphoma.

Purpose: We designed a CD19-targeted chimeric antigen receptor (CAR) comprising a calibrated signaling module, termed 1XX, that differs from that of conventional CD28/CD3ζ and 4-1BB/CD3ζ CARs. Preclinical data demonstrated that 1XX CARs generated potent effector function without undermining T-cell persistence. We hypothesized that 1XX CAR T cells may be effective at low doses and elicit minimal toxicities.

Purpose: Posterior fossa ring-enhancing lesions (PFREL) in the adult immunocompetent hosts pose a diagnostic challenge. We aimed to evaluate the spectrum of PFREL etiologies and propose a diagnostic algorithm.
Methods: This study involved a retrospective analysis of PFREL cases from our institution (January 2023 to April 2024) and a systematic literature review conducted using Embase and PubMed databases following the PRISMA 2020 guidelines.

Introduction: Burkitt lymphoma (BL) is a rare and aggressive subtype of non-Hodgkin's lymphoma. Several studies have identified prognostic factors (PFs) for disease progression and mortality among adults with BL. However, there is no consensus on risk stratification based on PFs.

Introduction: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare disease, with unique diagnostic challenges and often dismal outcome. There are no widely accepted treatment guidelines available. Lymphoma-like regimens with or without autologous or allogenic transplantation were the cornerstone of most therapeutic concepts.

CD7-targeted chimeric antigen receptor-T (CAR-T) cell therapy has shown great promise in the treatment of relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL). In this study, we reported a case of a 34-year-old male patient with T-ALL who finally developed multi-line drug resistance and refractoriness after multiple lines of high-intensity chemotherapy. After physician evaluation, this patient received allogeneic hematopoietic stem cell transplantation (allo-HSCT).
