This study aims to evaluate the diagnostic utility of fine needle aspiration cytology in mediastinal lesions, focusing on its accuracy, safety, and role in guiding therapeutic approaches. A cross-sectional retrospective analysis was conducted on patients who underwent fine needle aspiration for mediastinal lesions at our tertiary care centre between 2015 and 2024. Demographic data, cytological findings, histopathological correlation, and ancillary studies were reviewed. Diagnostic accuracy was assessed by comparing fine needle aspiration cytology findings with histopathological diagnoses. A cumulative total of 60 cases of mediastinal lesions were evaluated, of which 47 cases were considered suitable for cytological assessment. Among the 60 cases, 41 cases were identified as neoplastic (68.33 %), while 6 were classified as nonneoplastic (10 %) on cytology. Within the spectrum of neoplastic mediastinal lesions, lymphoma was recognised as the principal neoplastic entity, followed by thymic neoplasms and metastatic lesions. The overall diagnostic accuracy achieved through fine needle aspiration cytology in distinguishing these lesions was established at 83.8 %, with diagnostic accuracy being exceptionally high in metastatic lesions. Fine needle aspiration cytology of mediastinal lesions is a highly accurate, safe, and valuable diagnostic tool that significantly influences clinical management and treatment protocols. However, further studies with larger sample sizes and prospective designs are warranted to validate these results and refine procedural protocols.</div></div>","PeriodicalId":50768,"journal":{"name":"Annals of Diagnostic Pathology","volume":"79 ","pages":"Article 152520"},"PeriodicalIF":1.5,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144263809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to assess CA IX immunoreactivity across the spectrum of RCC with sarcomatoid differentiation. The expression of CA IX was evaluated in 32 cases of RCCs with sarcomatoid differentiation (12 clear cell RCC, 7 papillary RCC and 13 chromophobe RCC). Seven urothelial carcinomas (UC) with sarcomatoid differentiation (originally from renal pelvis) and 23 soft tissue tumors were also included as a control cohort. The sensitivity for CA IX in sarcomatoid component of clear cell RCC was 91.7 % (moderate/strong CA IX staining in >60 % of sarcomatoid component). However, the CA IX specificity was rather low (45 %), as a significant proportion of sarcomatoid components in different renal cell carcinoma subtypes also stained with CA IX (2/7 papillary RCC, 9/14 chromophobe RCC). When urothelial carcinoma and soft tissue tumors were included in the evaluation, the specificity of CA IX staining for sarcomatoid clear cell RCC reached 60 %. In conclusion, CA IX shows decent sensitivity for sarcomatoid clear cell RCC, but with low specificity, hence limiting its diagnostic utility as a reliable marker of in tumors with predominant sarcomatoid component.</div></div>","PeriodicalId":50768,"journal":{"name":"Annals of Diagnostic Pathology","volume":"79 ","pages":"Article 152517"},"PeriodicalIF":1.5,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144272305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors do not account for congenital anomalies such as thyroid hemi agenesis, which can alter tumor morphology independently of genetic mutations [2]. Additionally, coexisting autoimmune thyroid conditions like Hashimoto’s thyroiditis may confound nuclear features through inflammatory changes [3]. The study also overlooks the influence of demographic factors, such as age and gender, which are known to impact PTC prognosis and histology [4]. Reliance on a subjective nuclear scoring system without digital validation raises concerns about reproducibility and inter observer variability [5]. Addressing these gaps is significant to improve the diagnostic accuracy and clinical relevance of morpho-molecular correlations in Papillary Thyroid Carcinoma.

Key pathological variables were identified using logistic regression and used to develop a random forest classification model. Survival outcomes were analyzed using Kaplan-Meier and Cox regression analyses. The random forest model, using nine significant pathological features, achieved an overall classification accuracy of 83 %. Mucin production, tumor grade, and intraepithelial lesion were among the most influential predictors. The small duct type was associated with significantly better overall survival (5-year rate: 57.6 %) and recurrence-free survival (46.6 %) compared to the large duct type (24.9 % and 20.6 %, respectively). Multivariable analysis confirmed the large duct type as an independent predictor of worse prognosis. Histological subtyping of iCCA holds important prognostic value. The small duct type is associated with a more favorable clinical course, supporting the integration of subtype-aware assessments into diagnostic and prognostic frameworks.

In response, the World Health Organization (WHO) introduced reformulated categories in 2023 that reflect varying malignancy risks. To evaluate this revised classification, it is vital to correlate cytological results with biopsy findings. In this study, we reclassified previously diagnosed cases based on the new WHO cytological categories. Prospective cross-sectional study evaluated cytology samples from lung carcinoma patients at AIIMS Raipur (2019–2021) and, in 2024, reclassified them according to updated WHO categories, facilitating a new assessment of cytology sensitivity through descriptive statistics and calculations. In this study, 116 biopsy-confirmed primary lung carcinoma cases underwent cytological evaluation, with cell blocks prepared for 70 cases. Sample types included bronchoalveolar lavage (BAL) fluid (68 cases, 58.6 %), sputum (4 cases, 3.4 %), and fine needle aspiration cytology (4 cases, 3.4 %); remaining samples were pleural fluid, which were subsequently excluded. Following the adoption of new WHO classification categories in 2024, a retrospective analysis demonstrated a significant improvement in sensitivity, increasing from 36.8 % (28/76) to 65.8 % (50/76), which enhanced the detection of atypical, suspicious, or malignant cases. This study underscores the effectiveness and limitations of cytological examination in diagnosing primary lung carcinoma, demonstrating that many cases can be accurately identified. The new WHO cytology categories improve diagnostic accuracy, but sensitivity results suggest room for precision enhancement.
