AI Article Synopsis

  • Composite lymphoma is when two or more distinct types of lymphomas are found in the same location simultaneously.
  • The case presented involves a 62-year-old woman with both high-grade and low-grade B-cell lymphomas in her retroperitoneal lymph node and spleen.
  • Diagnosis was confirmed through histopathological examination and immunohistochemistry.

Article Abstract

Composite lymphoma refers to the co-occurrence of two or more morphologically and immunophenotypically separate lymphomas in the same topographic site at the time of clinical presentation. It is an infrequent type of lymphoid neoplasm, present in lymphoid tissue and may be due to the existence of two genetically related neoplasms such as transformation of a single lymphoma into another more aggressive lymphoma or be due to the presence of two clonally unrelated lymphomas. This paper is presenting a case of diffuse non-Hodgkin large B-cell lymphoma with areas of low grade and high grade follicular non-Hodgkin B-cell lymphoma in a retroperitoneal lymph node and spleen of an 62 year old woman. Histopathological examination and immunohistochemistry features proved the diagnosis of composite lymphoma.

The advent of spatial transcriptomics and spatial proteomics have enabled profound insights into tissue organization to provide systems-level understanding of diseases. Both technologies currently remain largely independent, and emerging same slide spatial multi-omics approaches are generally limited in plex, spatial resolution, and analytical approaches. We introduce IN-situ DEtailed Phenotyping To High-resolution transcriptomics (IN-DEPTH), a streamlined and resource-effective approach compatible with various spatial platforms.

Rituximab combined with systemic chemotherapy significantly improves the rate of complete response in B-cell lymphomas. However, acquired rituximab resistance develops in most patients leading to relapse. The mechanisms underlying rituximab resistance are not well-understood.

Background: The most frequent type of non-Hodgkin lymphoma (NHL) is diffuse large B-cell lymphoma (DLBCL). Although lymph nodes are the most commonly affected organs compromising 70% of DLBCLs, only 5% of extranodal lymphomas represent skeletal muscle involvement. Specifically, abdominal wall muscle involvement is rare and there are only a few reported cases of DLBCL with this type of muscle involvement.

January 2025

Tumour Biology and Immunology Laboratory, Research Branch, Sidra Medicine, Doha, Qatar.

Background: FFPE tissue samples are commonly used in biomedical research and are a valuable source for next-generation sequencing in oncology, however, extracting RNA from these samples can be difficult the quantity and quality achieved can impact the downstream analysis. This study compared the effectiveness of seven different commercially available RNA extraction kits specifically designed for use with FFPE samples in terms of the quantity and quality of RNA recovered.

Methods: This study used 9 samples of FFPE tissue from three different types of tissue (Tonsil, Appendix and lymph node of B-cell lymphoma) to evaluate RNA extraction methods.
