In general, the prognosis of these neoplasms is better than their systemic counterparts and this emphasizes the need for an accurate diagnosis for patients. Two main categories are recognized so far in PCBCL based on their clinical behaviour. Indolent PCBCL includes Primary cutaneous marginal zone lymphoma (PCMZL), Primary cutaneous follicle center lymphoma (PCFCL) and Epstein Barr virus-positive mucocutaneous ulcer (EBV + MCU). The more aggressive PCBCL are cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) and intravascular large B cell lymphoma. Since the publication of the updated WHO-EORTC classification in 2018, new consensus guidelines and classifications have been published in the field of cutaneous lymphomas incorporating new discoveries in their genetics alterations and immunophenotype. Here, we summarize the main clinical, histological and molecular characteristics of primary cutaneous B-cell lymphomas and reactive B-cell rich lymphoid proliferations, highlighting the most relevant findings published recently in the medical literature.</p></div>","PeriodicalId":39961,"journal":{"name":"Diagnostic Histopathology","volume":"30 8","pages":"Pages 419-429"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141405339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a significant proportion of lymphomas may initially present in the GI tract, associated with non-specific GI symptoms without strong clinical suspicion for haematological malignancy, it is crucial that general and gastrointestinal pathologists are familiar with these entities.
