Today, cytological smears are utilized for molecular testing more often than ever. Accurate tumor cell percentage estimation is essential for reliable molecular testing, but its consistency remains uncertain. This study evaluates the reliability of tumor cell percentage estimations among an expert cytopathologist, a molecular cytopathologist, and a molecular pathologist.Material and methods: Digital images from May-Grünwald-Giemsa (MGG)-stained smear slides of ten EBUS-guided mediastinal lymph node samples were selected. Five regions per slide were evaluated (50 areas from 10 patients). Three pathologists independently estimated tumor cell percentages using predefined categories (0-10%, 11-20%, 21-50%, etc.). Cells were also counted manually as the gold standard.Results: The molecular cytopathologist (Observer 1 -) showed the highest consistency (Kappa = 0.69), followed by the expert cytopathologist (Observer 3 -, Kappa = 0.64), both demonstrating substantial agreement with the gold standard. The molecular pathologist (Observer 2 -) displayed moderate consistency (Kappa = 0.52). Agreement was most significant in the 71-100% category, aligning in over 95% of cases. The lowest value occurred in the 11-20% category. In this category, tumor proportions were frequently overestimated compared to the gold standard.Conclusion: Variability in tumor percentage estimations shows the need for standardized protocols and training. Substantial agreement was reached in specific categories. However, discrepancies in borderline cases highlight the importance of accurate assessments. More research is needed to improve estimation methods.","PeriodicalId":45415,"journal":{"name":"Turkish Journal of Pathology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145245398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to describe a rare case of severe anemia secondary to Parvovirus B19 infection in a kidney transplant recipient, highlighting diagnostic and therapeutic challenges in the immunosuppressed setting.Case report: We present a 43-year-old woman with end-stage renal disease secondary to polycystic kidney disease who received a living-kidney transplant from her husband. Seven months after transplantation, she presented with severe anemia, fatigue, and palpitations. Laboratory findings demonstrated severe normocytic, normochromic anemia (Hb: 5.8 g/dL). Parvovirus B19 serology tests were negative twice, while PCR testing revealed a significant viral load (25×10⁶ copies/mL). Bone marrow biopsy findings included giant proerythroblasts with characteristic viral nuclear inclusions. The patient received intravenous immunoglobulin (IVIG, 100 mg/kg/day for 4 days), and mycophenolate mofetil was discontinued. After therapy, hemoglobin levels and viral load improved significantly, leading to successful resolution of anemia.Conclusion: This case emphasizes the importance of considering Parvovirus B19 in the differential diagnosis of anemia in transplant patients. In immunosuppressed individuals, PCR and bone marrow analysis can be essential for diagnosis, especially when serologic tests are inconclusive. Timely intervention can lead to favorable outcomes.","PeriodicalId":45415,"journal":{"name":"Turkish Journal of Pathology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144733804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous study, we proposed an algorithm that provides a systematic approach to intraoperative consultation for central nervous system tumors. Our aim was to demonstrate the effectiveness of this algorithm.Material and methods: 102 cases were selected from intraoperative consultation procedures performed at our institution between 2012 and 2020. The algorithm was tested by five observers. The observers examined the smears and frozen sections without the algorithm, and then with the algorithm.Results: The percentage change in the rate of correct diagnoses made by the four observers (O) increased after using the algorithm (O2: 8%, O3: 5%, O4: 8% and O5: 13%), but decreased for only one observer (O1) (5%). The most common error made by the four observers was `grading of glial tumors` (O1: 40%; O2: 23%; O4: 40% and O5: 27.5%), and this group of errors was mostly corrected by using the algorithm (O1: 33%; O2: 3.8%; O4: 23% and O5: 10%). For two observers (O2 and O5), a statistically significant change in diagnostic levels was observed after using the algorithm (p=0.024 and p=0.040; respectively). In addition, thanks to the use of the algorithm, a high degree of agreement was found between the observers` diagnoses (77.7%, p < 0.001).Conclusion: In the intraoperative consultation of central nervous system lesions, algorithms can help to increase the accuracy of the diagnosis and reduce interobserver variability. This study demonstrates that an algorithmic approach is an effective method for pathologists in intraoperative consultation procedures.","PeriodicalId":45415,"journal":{"name":"Turkish Journal of Pathology","volume":" ","pages":"9-15"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11831962/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Immunohistochemistry (IHC) for Smooth Muscle Actin (SMA) and special staining with Masson Trichrome (MT) were used to highlight fibromuscular areas whenever in doubt.Conclusion: The pathogenesis of SRUS is not well understood. It may be associated with chronic mucosal and hypoperfusion-induced ischemic injury to the rectal mucosa due to trauma or increased rectal pressure during straining.

The objective of this investigation is to study GBP-induced neurotoxicity in rats and the protective benefits of alpha-tocopherol (vitamin E `Vit E`).Material and methods: Forty (40) adult male albino rats were randomly split into four groups: (10 rats each): Group I, which was subdivided into group Ia (5 rats), received a regular diet as a negative control; group Ib (5 rats) received corn oil as a positive control; group II received alpha-tocopherol; group III (GBP misuse); and group IV received GBP + alpha-tocopherol. The corresponding medicines were administered to every rat for fifty days. Neurobehavioral tests were performed on the day of scarification. Hippocampal tissues were collected for immunohistochemical and histological analysis.Results: Weight gain rose considerably by the end of the research in the drug-treated groups. In neurobehavioral tests, controls performed better and had higher locomotor indices. The group that misused GBP showed more deteriorated cells and more negative effects on hippocampal tissues. These histological alterations dramatically decreased with alpha-tocopherol therapy.Conclusion: GBP in high doses had neurotoxic effects, disrupted hippocampal tissues, and increased the number of degenerated cells.

To present two cases of MINEN of the liver diagnosed in our centre with clinical & diagnostic workup, the treatment modalities, and follow up. Extensive review of the literature and compilation of the presentation and treatment modalities used in those cases.Case reports: Thirty-three cases of MINEN of the liver have been reported till date including ours. Our cases presented as incidental masses in liver during workup for other symptoms. AFP levels were normal in both cases but PIVKA (Protein induced by vitamin K absence) levels were increased. Resection was done in one of the cases while the other patient had to undergo transplantation. A diagnosis of MINEN was made on H&E, and confirmed on IHC. One patient was unfit for systemic chemotherapy whereas the other patient received cisplastin and etoposide based chemotherapy. Both patients developed metastasis on follow up but are still alive after 12-15 months.Conclusion: MINEN is an uncommon tumor of the liver with a poor prognosis as shown by the few studies available. Recurrence and distant metastases are often described even after complete resection and the course is fatal. The role of adjuvant chemotherapy following surgical resection is not fully elucidated. Mean survival in the cases reported ranged from 1 month to 33 months. However, no significant differences were seen in the clinicopathologic profile of the cases described so far. Further multiinstitutional studies and follow up will help to further characterize this subtype for appropriate treatment.","PeriodicalId":45415,"journal":{"name":"Turkish Journal of Pathology","volume":" ","pages":"21-29"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11831964/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
