Gastric marginal zone lymphoma (gMZBL) is the most frequent type of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). The histology of gMZBL shows typical small cell morphology, however, there also exists a large cell variant.

Primary central nervous system lymphoma (PCNSL) is a rare and aggressive extranodal Non Hodgkin Lymphoma. Combined modality treatment with high-dose methotrexate (HD-MTX) followed by whole brain radiotherapy (WBRT) has been a commonly used treatment approach.

Intravascular large B-cell lymphoma (IVLBCL) is a rare and specific variant of diffuse large B-cell lymphoma (DLBCL). Epstein-Barr virus (EBV)-positive IVLBCL is particularly rare and highly aggressive. Up to present, only a few cases of EBV-positive IVLBCL have been reported in the literature. Here, we would like to further explore its clinicopathological and molecular features to ensure the awareness and accurate diagnosis of this entity.

Sézary's Syndrome consists of a rare type of non-Hodgkin cutaneous T-cell lymphoma (CTCL), being a very aggressive leukemic variant of CTCL. Given its rarity and its ability to mimic other more common diseases, this neoplasm represents a major diagnostic challenge for both clinicians and pathologists.

Currently, the field of tumor nephrology continues to evolve, and the interplay between chronic kidney disease (CKD) and lymphoma merits further investigation. The incidence of CKD among lymphoma patients is substantial, posing a significant long-term risk for CKD progression. CKD should be regarded as an independent prognostic factor for mortality in lymphoma patients. In this mini-review, we aim to extend the research direction outlined in "Diagnosis and Treatment of Secondary Nephrotic Syndrome with Rash as the Initial Symptom: A Case Report", with a focus on elucidating the correlation between CKD and lymphoma.
