BACKGROUND: Fine-needle aspiration cytology (FNAC) of oral lesions has not been widely utilized for diagnosis due to rarity and diversity of lesions, peculiar anatomy of maxillofacial region, difficulty in aspirating these lesions, and limited experience. Aim of this study was to determine the role of FNAC in the diagnosis of @entity89 . MATERIALS AND METHODS: One hundred and forty two @entity1 underwent FNAC over a period of 7 years (2007-2013), of which 127 (89.4%) aspirates were diagnostic. Histopathologic correlation was available in 83 cases and diagnostic accuracy of FNAC was calculated. RESULTS: Of the minor salivary gland lesions, 41 out of 55 lesions (74.5%) were benign and 14 (25.4%) were malignant. Mucocele was the most common lesion in oral cavity (30 cases) and @entity5123 was the commonest @entity14253 (9 cases). Of the 72 non-salivary-gland lesions, 22 lesions were inflammatory, 4 were epidermal inclusion cysts, 21 were @entity5 , and the remaining 25 presented as radiolucent jaw @entity79 . Diagnostic accuracy of FNAC in our study was 91.6% with 6 false negatives and 1 false positive. Four @entity5 and one case of cystic @entity1567 were misdiagnosed as false negative on cytology. CONCLUSION: Cytological features are diagnostic in certain inflammatory lesions of infective etiology and @entity5 conditions like Langerhans cell histiocytosis, @entity706 , @entity6872 , @entity2828 , and @entity957 . However, accurate subtyping of giant cell lesions, @entity5 , odontogenic @entity5 , and @entity5409 may not be always feasible on FNAC. FNAC is highly accurate in early diagnosis of @entity89 .
