ABSTRACT
OBJECTIVES: The aim of this study was to evaluate the diagnostic accuracy and efficacy of Fine needle aspiration cytology (FNAC) in various salivary gland swellings. MATERIALS AND METHODS: This retrospective study was performed at Kathmandu Medical College Teaching Hospital (KMCTH) from January 2004- December 2006.During this period a total of 978 FNAC's were done out of which 40 FNAC's were on salivary gland swellings. Correlation was done between cytological smear slides and biopsy slides. RESULTS: In this series of FNAC, 16 cases (40%) were benign neoplasms, 5 cases (12.5%) malignant neoplasms, non-neoplastic cysts 3 cases (7.5%) and inflammatory lesions 16 cases (40%).Histopathology was available in 24 cases out of which 22 cases correlated with cytology. There were no false positive reports but false negative result was seen in 4 cases. Sensitivity and specificity were 90% and 100% respectively. CONCLUSION: FNAC is useful in the diagnosis of salivary gland swellings especially in benign conditions with a sensitivity of 90% and specificity of 100%.
ABSTRACT
OBJECTIVES: The cytological findings of 50 ST Ts were evaluated aiming to determine the role of FNA in diagnosis of STTs METHODS: Fifty patients with soft tissue tumours underwent FNA in the preoperative investigation during a one year period. The smears were stained with Papanicolaou and May-Graunvald Giemsa stains. RESULTS: Forty-four cases were reported as benign, whereas 2 were malignant. Four cases revealed insufficient material. The malignant STTs were small round cell tumour and malignant spindle cell tumour. Cytological and histological correlation could be achieved in 40 cases. The overall sensitivity and specificity were 25% and 100% respectively with overall accuracy of 80%. CONCLUSION: A reliable diagnosis of STTs can be made with FNA when supported by other clinical and other diagnostic data.

OBJECTIVES: The main objective of this study was to assess antral brush cytology as an alternate approach for the diagnosis of H. pylori infection as compared to histopathology. METHODS: 75 cases with diagnosis of antral gastritis underwent endoscopic antral biopsy as well as antral brushing cytology was included irrespective of age and sex. Cytological slides were stained with Giemsa stain & biopsy slides were stained with H&E and Giemsa stain. Correlation was done between cytological smear slides and biopsy slides. RESULTS: Among 75 cases, H. pylori were positive in 55 (73.4%) cases of biopsy specimens while in brush cytology it was positive in 48 (64%) cases. In 45 (60%) of 75 cases, H. pylori was seen in both biopsy and brush cytology. CONCLUSION: Endoscopic brush cytology provides an accurate, inexpensive and easy technique in the rapid detection of H.pylori infection.
