Pathology Informatics Essentials for Residents: A Flexible Informatics Curriculum Linked to Accreditation Council for Graduate Medical Education Milestones (a secondary publication)*

Context: Recognition of the importance of informatics to the practice of pathology has surged. Training residents in pathology informatics has been a daunting task for most residency programs in the United States because faculty often lacks experience and training resources. Nevertheless, developing resident competence in informatics is essential for the future of pathology as a specialty. Objective: To develop and deliver a pathology informatics curriculum and instructional framework that guides pathology residency programs in training residents in critical pathology informatics knowledge and skills, and meets Accreditation Council for Graduate Medical Education Informatics Milestones. Design: The College of American Pathologists, Association of Pathology Chairs, and Association for Pathology Informatics formed a partnership and expert work group to identify critical pathology informatics training outcomes and to create a highly adaptable curriculum and instructional approach, supported by a multiyear change management strategy. Results: Pathology Informatics Essentials for Residents (PIER) is a rigorous approach for educating all pathology residents in important pathology informatics knowledge and skills. PIER includes an instructional resource guide and toolkit for incorporating informatics training into residency programs that vary in needs, size, settings, and resources. PIER is available at http:// www.apcprods.org/PIER (accessed April 6, 2016). Conclusions: PIER is an important contribution to informatics training in pathology residency programs. PIER introduces pathology trainees to broadly useful informatics concepts and tools that are relevant to practice. PIER provides residency program directors with a means to implement a standardized informatics training curriculum, to adapt the approach to local program needs, and to evaluate resident performance and progress over time

Intraepithelial sebaceous carcinoma of the eyelid misdiagnosed as Bowen's disease

BackgroundSebaceous carcinoma (SC) is well known for its ability to masquerade clinically and histologically as a variety of periocular conditions resulting in a delayed diagnosis. We present a series of periocular SC cases and discuss the difficulties in histopathological diagnosis when this tumor presents with a Bowenoid pattern of intraepithelial spread.MethodsA retrospective case study of all patients with SC of the eyelid treated in our Hospital, from 1997 to 2004, was conducted.ResultsEight patients were identified (four females and four males). Seven cases involved the upper eyelid. Initial clinical diagnoses included blepharitis (three cases), blepharoconjunctivitis (one case), cicatrizing conjunctivitis (one case), and lid lesions (two cases). Histopathologically, 87.5% of cases were misdiagnosed as Bowen's disease (BD) on the initial biopsy. Six of these cases showed no invasive disease on the initial biopsy and were eventually found to be invasive SC on subsequent excisions. In one case, the tumor was wholly in situ. Delay in diagnosis ranged from 0 to 56 months.ConclusionsSC should always be considered in the histological differential diagnosis of any eyelid lesion which resembles BD, particularly if the upper eyelid is involved or if multivacuolated cytoplasmic clear cell changes are seen

Magnetic resonance imaging goes postmortem: noninvasive detection and assessment of myocardial infarction by postmortem MRI

OBJECTIVE: To investigate the performance of postmortem magnetic resonance imaging (pmMRI) in identification and characterization of lethal myocardial infarction in a non-invasive manner on human corpses. MATERIALS AND METHODS: Before forensic autopsy, 20 human forensic corpses were examined on a 1.5-T system for the presence of myocardial infarction. Short axis, transversal and longitudinal long axis images (T1-weighted; T2-weighted; PD-weighted) were acquired in situ. In subsequent autopsy, the section technique was adapted to short axis images. Histological investigations were conducted to confirm autopsy and/or radiological diagnoses. RESULTS: Nineteen myocardial lesions were detected and age staged with pmMRI, of which 13 were histologically confirmed (chronic, subacute and acute). Six lesions interpreted as peracute by pmMRI showed no macroscopic or histological finding. Five of the six peracute lesions correlated well to coronary pathology, and one case displayed a severe hypertrophic alteration. CONCLUSION: pmMRI reliably demonstrates chronic, subacute and acute myocardial infarction in situ. In peracute cases pmMRI may display ischemic lesions undetectable at autopsy and routine histology. pmMRI has the potential to substantiate autopsy and to counteract the loss of reliable information on causes of death due to the recent disappearance of the clinical autopsy
