Abstract PDF: Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy, characterized by a range of subtypes that differ in their cytologic features, clinical behavior, and prognosis. Accurate cytologic evaluation of PTC using fine-needle aspiration is essential but can be challenging due to the morphologic diversity among subtypes. This review focuses on the distinct cytologic characteristics of various PTC subtypes, including the classic type, follicular variant, tall cell, columnar cell, hobnail, diffuse sclerosing, Warthin-like, solid/trabecular, and oncocytic PTCs. Each subtype demonstrates unique nuclear features, architectural patterns, and background elements essential for diagnosis and differentiation from other thyroid lesions. Recognizing these distinct cytologic patterns is essential for identifying aggressive subtypes like tall cell, hobnail, and columnar cell PTCs, which have a higher risk of recurrence, metastasis, and poorer clinical outcomes. Additionally, rare subtypes such as diffuse sclerosing and Warthin-like PTCs present unique cytologic profiles that must be carefully interpreted to avoid diagnostic errors. The review also highlights the cytologic indicators of lymph node metastasis and high-grade features, such as differentiated high-grade thyroid carcinoma. The integration of molecular testing can further refine subtype diagnosis by identifying specific genetic mutations. A thorough understanding of these subtype-specific cytologic features and molecular profiles is vital for accurate diagnosis, risk stratification, and personalized management of PTC patients. Future improvements in diagnostic techniques and standardization are needed to enhance cytologic evaluation and clinical decision-making in thyroid cancer.

Abstract PDF: Since the late 1990s, online e-learning has offered unparalleled convenience and affordability, becoming increasingly popular among pathologists. Traditional learning theories have been successfully applied to web/mobile-based learning systems, with mobile technologies even enhancing conventional offline education. In cytopathology, hands-on microscope training has traditionally been paramount, complemented by real-case presentations and lectures. However, the coronavirus disease 2019 (COVID-19) pandemic disrupted regular academic activities, making online e-learning platforms essential. We designed a web/mobile-based learning platform to enhance continued medical education in cytopathology at various levels, particularly during the era of COVID-19 and beyond. Since 2021, we have integrated curriculum materials, virtual education files, and whole-slide images (WSIs) of cytopathology, submitted from over 200 institutions across Korea, with the support of numerous instructors. We develop a new e-learning platform named “CytoAcademy” composed of a basic session for each organ and level across the range of morphologic findings; on-demand lectures to enhance cytopathologic knowledge; WSI archives that allow users to explore various histologically confirmed cases; and a self-assessment test to help organize diagnostic knowledge acquired through the web/mobile-friendly learning system. The platform provides not just an opportunity to achieve a correct diagnosis, but also a learning experience based on problem-solving point. Members interact, identify their deficiencies, and focus on specific educational materials. In this manner, all participants can actively engage in creating and maintaining knowledge and foster a proactive approach to learning.

Abstract PDF

The importance of professional and ethical behavior by physicians both in training and in practice cannot be overemphasized, particularly in pathology. Professionalism education begins in medical school, and professional attitudes and behaviors are further internalized during residency. Learning how to be a professional is a vital part of residency training. While hospital- or institution-based lecture style educational programs exist, they are often ineffective because the curriculum is not applicable to all specialties, although the basic concepts are the same. In this paper, the author suggests ways for institutions to develop professional attitude assessments and to survey residents’ responses to various unprofessional situations using case scenarios.

Abstract PDF: Diffuse interstitial lung disease(DILD) is a large group of heterogeneous diseases that diffusely involve the pulmonary connective tissues, principally subpleural, interlobular and alveolar wall portions. Terminology and classification of these diseases are not uniform, and the cause and the pathogenesis are unknown in many entities. It is generally accepted that the response to therapy is related to the relative degree of cellularity and fibrosis present, therefore a histologic evaluation of the relative extent and severity of these changes is required. We reviewed 52 cases of DILD from January 1990 to May 1995 diagnosed by open lung biopsy to reappraise classification and quantitative assessment of the histopathologic features. Differential histopathologic features between usual interstitial pneumonia(UIP) and nonspecific interstitial pneumonia(NIP) were examined with a correlation of HRCT findings and clinical findings. Among 52 cases of DILD, 18 cases(34.6%) were UIP, 6 cases(11.5%) were hypersensitivity pneumonia was NIP was 5 cases(9.6%), interstitial lung diseases associated with the connective tissue diseases were 5 cases(9.6%), inorganic dusts were 4 cases(7.7%), infections were 4 cases(7.7%), durgs were 2 cases(3.8%), acute interstitial pneumonia was 1 case(1.9%), sarcoidosis was 1 case(1.9%) in order of frequency plus 6 other cases(11.5%). UIP was the most frequent DILD in this study which seemed to be a criteria bias of patient selection on open lung biopsy. Quantitative assessment of histopathologic features was useful in the differential diagnosis of DILD and differentiation of UIP from NIP was possible based on histopathologic features and supported by HRCT. UIP disclosed a significantly high score of fibrotic changes, especially in the interstitial fibrosis, smooth muscle proliferation and honeycombing, otherwise NIP appeared relatively high score in inflammatory changes. Correlation between histopathologic scores and the clinical outcome after steroid therapy or no therapy in UIP was not evident.
