Objective False positive and negative results are associated with biliary tract cell brushing cytology during endoscopic retrograde cholangiopancreatography (ERCP). The causes are uncertain. The purpose of this study was to evaluate the accuracy of diagnoses made via cell brushing in our center, and to explore the factors influencing diagnosis. Methods The clinical data of patients who underwent cell brushing at our center from January 2016 to August 2019 were retrospectively analyzed. These included age, gender, stricture location, thickness of the bile duct wall in the narrow segment, maximum diameter of the biliary duct above the stricture, number of cell brush smears, carbohydrate antigen 19-9, and carcinoembryonic antigen. Positive brush cytology results were compared with results of surgical histology or tumor biopsy as well as with the patient’s clinical course. Results Of the 48 patients who underwent cell brushing cytology, 27 (56.3%) had positive results. The sensitivity and specificity of biliary duct cell brushing was 79.4%, and 85.7%, respectively. None of the above-mentioned factors were associated with positive cytology brushing results. Conclusions Cell brushing cytology remains a reliable method for diagnosis of pancreaticobiliary malignancies.

Cytology Study

INTRODUCTION: Bronchoscopy is a safe and effective method for diagnosing lung carcinomas with a variation in the diagnostic yield with different bronchoscopy guided procedures. Cell block technique has shown an addition cases positivity in diagnosing carcinomas as compared to the conventional method. AIM: The present study was aimed to evaluate the diagnostic utility of cell block technique on Bronchoscopy guided needle aspiration/ Brush and also to compare cytological preparation with cell block. MATERIAL AND METHODS: A total of 50 cases were included in the study that was suspected to be having lung carcinoma. These patients went under bronchoscope guided aspirations (TBNA, EBNA, and Brush). Smears were immediately made for conventional cytology study and well as in another aliquot samples were collected to prepare cell blocks following which H&E staining was done. RESULTS: Out of 50 cases, 8 cases came out to be negative on conventional smears and when compared with cell block technique 4 additional cases came out to be positive who were negative on conventional smears. The diagnosis were compared with histopathology biopsies keeping it as a gold standard and results on cell block techniques were conrmed to be true. CONCLUSION: Out of 50 cases, an additional 4 more cases were diagnosed malignant by using the cell blocks technique but there were few drawbacks with cell block technique. In few of the cases on cell block, cellularity was very less, cells morphology was also not very clear and some showed cells entrapped in a clusters. The conclusion made out of this study is that cell block technique is more accurate than the cytological smears and when used in combination diagnostic efcacy will be improved.

Renal leiomyosarcoma is a very rare tumor that clinically and radiographically mimics more common renal malignancies. The infrequency of the condition makes it very difficult to diagnose. A 70-year-old male smoker presented with months of hematuria, right-sided flank pain, and weight loss. Imaging revealed a 3.8-centimeter renal mass that had characteristics similar to renal cell carcinoma. Initial biopsy of the mass was negative for malignancy. Two months later, subsequent imaging revealed what appeared to be metastatic bone lesions. Again, a biopsy of one of the lesions was negative for malignancy. Subsequent ureteral pyeloscopy, ureteroscopic renal pelvis biopsy, and brush cytology were negative for malignancy as well. The decision was made to perform nephrectomy for the removal of the mass. Pathologic analysis revealed renal leiomyosarcoma. This case illustrates the difficulty in diagnosing renal leiomyosarcoma. Repeated pathologic sampling was negative because of the tumor heterogeneity. Prompt diagnosis and treatment are very significant as surgical resection at an early stage offers the best prognosis.
