Background: The cell block technique is one of the oldest method for evaluation of body cavity fluids and it increases the sensitivity of the diagnosis in comparison to conventional smear study. The main advantage of cell block technique is preservation of tissue architecture and obtaining multiple sections for special stains. Aim: To assess the utility of cell block method in increasing the sensitivity of cytological diagnosis of body cavity effusions as an adjunct to conventional smear method. Material and methods: It was institution based cross sectional observational study. All patients presenting with effusion and those who was give consent for participating in the study was included in this study. The study was conducted in Dept. Of Pathology, Nandigram Superspeciality Hospital. 100 cases fulfilling the predetermined inclusion and exclusion criteria was taken during the study period. Result: Association of Cellularity vs cell block was statistically significant (p<0.0001). Association of Architectural Pattern vs cell block was not statistically significant (p=0.7883). Association of cytological smears vs cell block was statistically significant (p=<0.0001). Conclusion: Cell block technique is superior to conventional smear technique, especially for malignant effusions.

F.NA.C has been used for ages as a safe and economical tool for fast preoperative diagnosis of parotid tumors. It has certain pitfall which sometimes leads to misdiagnosis and consequently it may have affect on treatment of the tumors. Keeping in view of the diverse classification of parotid tumors’ information from cytology should be combined with radiology as well as clinical diagnosis. Aim: To discuss some cases where there was discrepancy between cytological diagnosis and histopathological result and also suggest measures to improve the efficacy of F.N.A.C. Material and methods: The study includes 50 cases of parotid tumours who presented to the  department of ENT at Government medical college Haldwani which is a tertiary referral centre during 2009 to 2016. Only adult patients were included and inflammatory swelling were excluded from the study. All patients evaluated  Contrast enhanced computerized tomography(CECT) and  Magnetic resonance imaging (MRI) followed by Fine needle aspiration cytology .Preoperative diagnosis was made upon the findings of the above investigations and different types of  parotid surgeries  were done. . Final diagnosis was made on  histopathological  examination. Result :The most common tumour  came out to be pleomorphic adenoma (23 cases-46%) followed by mucoepidermoid carcinoma(12cases-24%). In ten  cases there was no clear cut  association between cytological diagnosis and final histopathological diagnosis. Conclusion: FNAC is highly sensitive and specific technique for diagnosis of many salivary gland swellings. FNAC can be used preoperatively to avoid unnecessary surgery and biopsy. Details of clinical information and radiologic features may help the pathologist to arrive at the appropriate diagnosis and reduce false interpretation. Pitfalls may also occur with improper technique of FNAC which can be overcome by proper caution.

Cytohistological comparisons to the account of the clinical data and revision of cytological and histological preparations on a material received from 21 patients are made. Cytomorphological features of juvenile nevi (Spitz-nevus, Reed-nevus), dysplastic and atypical nevi and early forms of melanoma are described. The establishment at cytological examination of good-quality character of melanocytic defeats at the account of the clinical data could be the basis for appointment laser therapy. At revealing of atypical melanocytes in cytological preparations patients should be referred to specialized oncological institutions for surgical excision of tumor with the subsequent histological examination. Thus cytological examination could be used in dermatological practice as a method of screening pre-malignant melanocytic tumors and skin melanoma.

AbstractOur aim was to investigate the diagnostic yield of rapid T1-mapping for the differentiation of malignant and non-malignant effusions in an ex-vivo set up. T1-mapping was performed with a fast modified Look-Locker inversion-recovery (MOLLI) acquisition and a combined turbo spin-echo and inversion-recovery sequence (TMIX) as reference. A total of 13 titrated albumin-solutions as well as 48 samples (29 ascites/pleural effusions from patients with malignancy; 19 from patients without malignancy) were examined. Samples were classified as malignant-positive histology, malignant-negative histology and non-malignant negative histology. In phantom analysis both mapping techniques correlated with albumin-content (MOLLI: r = − 0.97, TMIX: r = − 0.98). MOLLI T1 relaxation times were shorter in malignancy-positive histology fluids (2237 ± 137 ms) than in malignancy-negative histology fluids (2423 ± 357 ms) as well as than in non-malignant-negative histology fluids (2651 ± 139 ms); post hoc test for all intergroup comparisons: < 0.05. ROC analysis for differentiation between malignant and non-malignant effusions (malignant positive histology vs. all other) showed an (AUC) of 0.89 (95% CI 0.77–0.96). T1 mapping allows for non-invasive differentiation of malignant and non-malignant effusions in an ex-vivo set up.
