Clinical pathology selected abstracts

December 2025—The American Gastroenterological Association formalized, in 2020, iron-deficiency anemia recommendations for postmenopausal women and for men, which include esophagogastroduodenoscopy and colonoscopy, or bidirectional endoscopy. This guideline only conditionally recommended that bidirectional endoscopy be performed on premenopausal women, who are more likely to have iron-deficiency anemia (IDA) due to menorrhagia. The association also advised revising the World Health Organization’s recommended iron-deficiency diagnostic threshold of 15 ng/mL or lower ferritin to 45 ng/mL or lower. The authors used population-representative data from the National Health and Nutrition Examination Survey (NHANES) to assess the role of these recommendations in IDA prevalence estimates and management in the United States.

Anatomic pathology selected abstracts

December 2025—Unusual morphologic patterns of breast carcinoma can raise diagnostic consideration for metastasis or special breast cancer subtypes and, thereby, impact clinical management and treatment. The authors conducted a study in which they described rare invasive breast cancers that mimic serous carcinoma of the gynecologic tract (serous-like breast carcinomas, SLBC) and characterized their clinicopathologic, immunophenotypic, and genetic features. The patients evaluated in the study were female (n = 15; median age, 49 years) and did not have a history of gynecologic malignancy. SLBC were characterized histologically by angulated, branched, sometimes anastomosing glands with micropapillary or pseudopapillary luminal projections in desmoplastic stroma. Most SLBC were triple negative (n = 10) or HER2 positive (n = 2) and grade 2 or 3, while some were estrogen receptor low positive/HER2 negative and low grade (n = 3). CK5/6 was positive irrespective of grade or receptor status (10 of 10).

Molecular pathology selected abstracts

December 2025—Two studies explore the evolution of Mycobacterium tuberculosis and the significance of GATA1 mutations in children with Down syndrome. The first study reveals diversity in virulence gene expression across Mtb clinical isolates, with variants in the regulator whiB6 linked to decreased expression of virulence factors and increased transmission of drug-resistant strains. The second study investigates the clinical significance of GATA1 mutations in neonates with Down syndrome, finding that the presence of GATA1s mutations at birth is a strong predictor of myeloid leukemia associated with Down syndrome (ML-DS).

December 2025—Mayo Clinic recently introduced Mayo Clinic Platform_Insights, an offering designed to advance the adoption of artificial intelligence by giving health care organizations around the world access to Mayo Clinic’s digital expertise, data-driven insights, and clinical knowledge. “When organizations partner with us, they gain access to proven clinical and administrative solutions and the technical framework to integrate them seamlessly,” according to a press statement from Maneesh Goyal, chief operating officer for Mayo Clinic Platform, an initiative that brings together health systems, innovators, and researchers to support responsible AI development worldwide.

Q&A column

December 2025
Q. Now that the CMS allows direct observation for competency assessment to be performed virtually, does the CAP also allow it? If so, can you provide guidance? Read answer.

Q. We have implemented quality control at 10x in accordance with the Westgard rules. I use three levels of QC. If the results of two levels of QC are moving properly above and below the mean and only one level is showing a trend of a 10x rule violation, what corrective action should I take? Read answer.

Put It on the Board

December 2025—A new Clinical and Laboratory Standards Institute document on external laboratory transport is expected to be released early next year. “It’s the first comprehensive framework for evaluating external specimen transport systems,” says Joe Wiencek, PhD, D(ABCC), document development chair and medical director and associate professor of pathology, microbiology, and immunology at Vanderbilt University Medical Center.

From the President’s Desk

November 2025—Connecting with others is crucial for strengthening the pathology profession and improving patient care. This includes connecting with colleagues, patients, and other clinical partners to share ideas, resources, and expertise.

Letters: Why I chose pathology

November 2025—Nicholas Barron, an osteopathic medical student, chose pathology after a personal health experience highlighted the field’s importance in diagnosis and healing. Izak B. Dimenstein supports the American Association of Pathologists’ Assistants’ definitions for pathologists’ assistants and grossing technicians, advocating for specialized training and certification programs to ensure quality assurance in surgical pathology.

Clinical pathology selected abstracts

November 2025—A study analyzed data from 6,068 individuals who received a commercial blood-based CRC screening test between May 2022 and September 2024. The study found that 49% of individuals with an abnormal result received a follow-up colonoscopy within six months, with a mean time of 66.4 days.

Anatomic pathology selected abstracts

November 2025—A HER2-low–focused IHC scoring system was validated by nine breast pathologists using digitized images of HER2 IHC slides. The system demonstrated high performance metrics, including accuracy, sensitivity, and specificity, across two data sets, validating its effectiveness.
