Abstracts

Anatomic pathology selected abstracts

February 2025—Pulmonary complications cause significant morbidity and mortality in post-hematopoietic stem cell transplantation. The histopathology of pulmonary diseases in the context of post-hematopoietic stem cell transplantation (post-HSCT) is poorly characterized, especially in the pediatric population. The authors sought to characterize the pathologic spectrum of pulmonary disease post-HSCT in a pediatric cohort. Fifty-six specimens, including 53 biopsy specimens, corresponding to 53 patients were identified. Biopsy slides were reviewed and assigned to diagnostic categories (infectious, graft-versus-host disease, vasculopathy, indeterminate, and others) by consensus among three pediatric pulmonary pathologists, taking into consideration pathologic, clinical, radiologic, and laboratory findings.

February 2025—Low titer group O whole blood is commonly used for severe bleeding in trauma patients. It may also benefit pediatric patients undergoing cardiopulmonary bypass who are at risk for massive bleeding and coagulopathies. Circuit anticoagulation, hypothermia, hemodilution, coagulation factor, platelet loss and dysfunction, an underdeveloped hemostasis system in patients younger than two years old, and other factors lead to a higher risk of bleeding. Compared with component therapy, whole blood contains higher concentrations of RBCs, platelets, and coagulation factors, as well as cold platelets with enhanced hemostatic function. Due to the logistical challenges of donor centers providing ABO-specific whole blood for cardiopulmonary bypass (CPB), the use of longer storage-age low titer group O whole blood (LTOWB) may be an option for younger pediatric patients with severe bleeding on CPB.

February 2025—Excision repair cross-complementation group two (ERCC2) is a tumor-suppressor gene involved in DNA repair. Compound heterozygous mutations in ERCC2 are linked to rare recessive disorders, such as xeroderma pigmentosum, Cockayne syndrome, and trichothiodystrophy, all of which are characterized by ultraviolet light sensitivity. Somatic ERCC2 mutations in cancers, particularly bladder cancers, have emerged as significant prognostic markers. The mutations predict platinum sensitivity and correlate with favorable outcomes in patients with bladder cancer, but they have not been identified as independent prognostic indicators due to a lack of data, resulting from limited cohort sizes. The authors conducted a study in which they investigated the impact of ERCC2 hotspot mutations on genomewide mutagenesis and their implications for cancer prognosis and therapeutic stratification.

January 2025—The Food and Drug Administration published a letter in December 2021 detailing the risk of false-positive rapid plasma reagin test results when using Bio-Rad Laboratories’ BioPlex 2200 Syphilis Total and RPR kit to test people who had received the COVID-19 vaccine. It did not appear that Treponema pallidum particle agglutination assays were impacted by this issue. Several U.S. and Canadian blood collection organizations noted an unconfirmed increase in syphilis screening test reactivity rates, including unconfirmed repeat reactive rates, during the COVID-19 pandemic. In an investigation of this issue at the authors’ institution, which involved assessing syphilis testing records, the authors saw no change in nontreponemal testing results but did observe an incidental increase in test reactivity with the Beckman Coulter PK TP Microhemagglutination assay for detecting T. pallidum antibodies in 2020 and 2021. The authors conducted a study to explore the false-positive syphilis results using a different institutional assay and calculate the reactivity rate of syphilis screening with negative confirmatory testing from 2011 to 2023.

January 2025—The World Health Organization’s diagnostic criteria for malignant phyllodes tumor may miss a significant number of such tumors that have metastatic potential, according to a study conducted by the authors. Therefore, the authors proposed new refined diagnostic criteria for malignant phyllodes tumor (MPT) and conducted a study to validate the refined criteria. Their validation study included 136 borderline phyllodes tumors (BoPTs) and MPT cases that were not included in the initial study. The authors evaluated tumor classifications based on the refined criteria and World Health Organization (WHO) criteria. The revised criteria for MPT were either stromal overgrowth and one or more other features, such as marked stromal cellularity, marked stromal cytologic atypia, or at least 10 mitoses per 10 high-power fields (10 mitoses/10 HPF), or it was absence of stromal overgrowth and one or more other features, such as marked stromal cytologic atypia, at least 10 mitoses/10 HPF, or permeative border.

January 2025—Mismatch repair deficiency is a critical biomarker for identifying patients who may benefit from immunotherapy, and accurate classification is essential to making personalized treatment decisions. The authors conducted a study in which they presented a deep learning-based approach for classifying mismatch repair deficiency (MMR-D) in endometrial cancer using whole slide images of H&E-stained slides. They employed a multiresolution ensemble learning model in which they processed whole slide images at three magnifications—2.5×, 5×, and 10×—using a combination of the deep-learning architectures InceptionResNetV2, EfficientNetB2, and EfficientNetB3. These networks were trained on a data set of 1,168 whole slide images from 325 patients, with each whole slide image labeled by a pathologist for MMR-D or MMR proficiency (MMR-P) based on IHC results for the key MMR proteins MLH1, MSH2, MSH6, and PMS2. The authors addressed color variability in the H&E slides using a CycleGAN-based network for color normalization, ensuring consistency across the data set.

January 2025—Autism spectrum disorder is a neurodevelopmental disorder that has behavioral and social effects. Average patient age at diagnosis is approximately five years old. However, symptoms can appear within the first 12 months of life. The symptoms and severity of autism spectrum disorder (ASD) vary widely. They can include difficulty with verbal and nonverbal societal interaction, limited or repetitive behaviors, varying intellectual abilities, and emotional dysregulation.

December 2024—Excitement over the impact of artificial intelligence-based tools in different areas of health care has prompted position papers and research on the application of these new devices. One such tool is ChatGPT, which is publicly available and has demonstrated domain-specific knowledge in numerous areas, including medicine. The vast amount of data generated with current technologies, including digital pathology applications, and in subspecialty areas of pathology may lend itself to interpretation with artificial intelligence-based algorithms. But while AI-based applications can automate routine tasks and enhance diagnostic accuracy, their widespread use has been limited. Further AI research and validation of AI-based applications will increase adoption of such technology and, thereby, the overall efficiency and accuracy of the diagnostic process in pathology.

December 2024—Recurrence of Crohn’s disease within one or two years of resection is common. The authors conducted a study in which they sought to identify histologic features in Crohn’s disease resections that may predict earlier recurrence (18 months or less) to potentially guide postoperative management. They performed a single-institution, retrospective database review of 41 patients who had first-time Crohn’s disease bowel resection specimens collected between October 2002 and December 2007. Patient demographics and Crohn’s disease course were documented. Slides were reviewed for the distribution and composition of inflammation, small bowel pyloric metaplasia, and the presence and characteristics of submucosal fibrosis and granulomas.

December 2024—Acute promyelocytic leukemia is generally characterized by presence of the PML::RARA fusion. However, a subset of cases with morphological, cytochemical, and immunophenotypic features of acute promyelocytic leukemia (APL) lack this canonical fusion gene and instead present with alternate fusions. These include RARA fusions with partners other than PML and fusions involving other retinoic acid receptor (RAR) genes, such as RARG. Leukemias with these variant fusions often resist all-trans retinoic acid (ATRA) therapy. Specifically, the ATRA sensitivity of RARA fusion genes varies based on its 5′ fusion partner. Interestingly, in some studies, the artificially induced variant RAR bipartite fusion genes responded well to ATRA.
