Cytokeratin, melanocytic and mesenchymal markers were negative, so a provisional diagnosis of undifferentiated pleomorphic sarcoma (UPS), grade 3 was suggested. However, upon tertiary review of the CD138, there was focal weak positivity, triggering further haematological work up, including immunoglobulin heavy chain gene analysis which ultimately detected a heavy chain gene rearrangement. Thus, a diagnosis of a sarcomatoid plasma cell tumour was made. This case demonstrates the importance having plasma cell tumours within histopathologist's differential diagnoses when posed with a sarcomatoid tumour. It also highlights the need for judicious interpretation of IHC, and the use of a wide panel of IHC to ensure that correct histopathological diagnoses are made.</div></div>","PeriodicalId":39961,"journal":{"name":"Diagnostic Histopathology","volume":"31 5","pages":"Pages 300-303"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924814","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 the classification of cancers grows ever more complex, with subtypes defined by both conventional histopathological features and novel molecular techniques, it is becoming increasingly important to take account of histopathology in cancer epidemiology research. This review discusses selected examples of where appropriate integration of histopathology into clinical trials and observational epidemiological studies has enabled clinically-important insights into cancer aetiology and survival, including: identifying drugs which are effective in specific molecularly-defined cancer subtypes; demonstrating the value of histopathological variables in predicting survival in breast and ovarian cancers; gaining novel insights into contrasting risk factors for histological types of oesophageal cancer; and using epidemiology to complement histopathology in strengthening the evidence base for the origins and prevention of ovarian cancer. Work is ongoing to integrate histopathology data, including digital slides, into large population health resources such as the 100,000 Genomes Project and the UK Biobank cohort, which will eventually provide rich and complex datasets for exploring histopathology-related questions on a population level. However, expert clinical pathology involvement will be essential to ensure this future work remains scientifically robust and clinically relevant.</div></div>","PeriodicalId":39961,"journal":{"name":"Diagnostic Histopathology","volume":"31 5","pages":"Pages 290-299"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924822","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}

Properly developed and validated AI-based tools could improve the quantification of known biomarkers, identify novel tissue-based biomarkers beyond human perception, and enable inter-sample comparisons to reveal disease subtypes and heterogeneity. This article draws on our practical experience working with pathologists to develop AI-based algorithms for assessing bone marrow in patients with blood cancer. We provide an overview of approaches to AI model development from perspectives typically of most interest to our pathologist collaborators: the data requirements and the resulting model interpretability. We discuss the limitations of the current manual assessment of histopathology samples and the opportunities provided by AI-based approaches. We then address major challenges in the field and discuss how an interdisciplinary approach combining expertise across disciplines is essential to maximizing the potential of AI-powered pathology tools.</div></div>","PeriodicalId":39961,"journal":{"name":"Diagnostic Histopathology","volume":"31 5","pages":"Pages 277-283"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924810","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}

This process, often complex and detailed, requires a systematic, stepwise approach. Initially, pathologists must identify the overall injury pattern at low magnification, providing a foundation for further investigation. Once the injury pattern is recognized, it is essential to carefully examine the biopsy for distinctive microscopic features that may provide additional diagnostic clues. Many hepatic injury patterns are linked to well-established differential diagnoses, which help guide the diagnostic process. The assessment of a liver biopsy extends beyond simply identifying injury patterns. It requires a thoughtful integration of pathological findings, differential diagnoses, the patient's clinical presentation, as well as relevant laboratory tests and imaging studies. This comprehensive approach is essential, as it offers invaluable insights into the underlying etiology of the liver disease. In this review, we will focus on the most commonly encountered hepatic injury patterns.
