Background: Prostate cancer represents the second most frequently diagnosed malignancy among the male and fth leading cause of death. Tumour grade is one of the most important prognostic factors of prostate cancer. There are many markers studied in prostatic cancers, but the most extensively studied one is Ki-67, the proliferative marker. Prostatic cancers with Ki-67 over expression are generally aggressive. Aim And Objectives: - Aim of this study is evaluate ki67 immunoexpression in adenocarcinoma of prostate and to correlate with histopathological grade (Gleason Grade). This is single centre cross sectional study. The patie Material Methods:- nt who visited department of urology and renal transplant in Gauhati medical college and hospital and whose TRUS guided biopsy were received in the pathology department and diagnosed as adenocarcinoma were included. A total 50 cases were analysed. Tumour grade was determined according to Gleason's grading system and Ki-67 expressions were determined by IHC staining. The obtained results were analysed and evaluated using Chi square test (IBM SPSS version 21). Result And Interpretation:- A statically signicant correlation found between Gleason Grade and Ki-67 immuno expression with a p value of <0.001. In this study a statistically signicant correlation was found between Conclusion: - Gleason Grade and ki-67 labelling index. Hence Ki-67 immunoexpression evaluation and its result can be incorporated with histopathology which may inuence clinical decision making as prognosis of prostate cancer.
Background:- It is very rare that cytological diagnosis of papillary thyroid carcinoma by FNAC could not be conrmed by histological evaluation. One of the reasons for positive cytological nding and negative histological nding of papillary thyroid carcinoma is false positive diagnosis. Hashimoto's thyroiditis an autoimmune disease can be so extensive may mimic as papillary thyroid carcinoma because it may cause massive destruction of thyroid gland and may show similar nuclear features like Ptc. A Case Report:- 35-year old female, with a midline neck swelling of size (4x3)cm2 for one year. On FNAC the thyroid swelling was diagnosed as suspicious for papillary thyroid carcinoma. (Bethesda category v). However post operative diagnosis was conrmed as Hashimoto's thyroiditis. Hi Conclusion:- stomorphology in conjunction with biochemical ndings are necessary to conrm diagnosis of Hashimoto's Thyroiditis. False positive FNAC result is a pitfall of FNAC. Awareness of cytopathologist about pitfall of FNACS and strict adherence to adequacy criteria can reduce false positive rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
