Introduction: Neck masses are any swellings or enlargements in the region between inferior border of mandible and clavicle. Neck masses are a common cause of diagnostic dilemma to clinicians. Material and methods: The present is observational study with total 100 patients scanned on Ultrasound machine in supine position with slight neck extension after proper informed consent. FNAC was done for correlation. Results :Out of 100 patients of neck lesion maximum 49 (49 %) cases showed thyroid lesions of which 30 were malignant and 19 were benign. Lymph node lesions were the second most common lesions i.e. 24 (24%) of which 15 cases constitutes malignant followed by 9 which were benign. Sensitivity of USG in diagnosing Benign and malignant lesions was 81% with a Specificity 92% PPV 94% NPV 78%. Therefore, the diagnostic accuracy was 86%. Conclusion: Ultrasonography is a useful modality for diagnostic evaluation of neck masses in every age group. It is simple, non-invasive and inexpensive diagnostic imaging modality. It provides accurate and reproducible results. [ABSTRACT FROM AUTHOR]

Introduction: In India, oral cancer represents a major health prob !em and most of the malignancies arising from the various sub sites of the oral cavity are squamous cell carcinomas In the developing world oral cavity is common site of carcinoma after lung, stomach and liver in males while in females it is the fifth commonest cancer after cervix, breast, stomach and lung. Oral cavity is a common site for many types of benign and malignant tumors Material and Methods: This was a cross sedional observational study of patients detected to have oral cavity malignancy. All patients with clinically suspected and incidentally detected oral cavity malignancy attending to the tertiary care center and medical college where the study was conduded. A total of 50 patients diagnosed with oral cavity malignancy . Results: We found Correlation between nodal clinical staging and MRI staging. 10 Number of MRI Staging cases and 25 Number of Clinical Staging cases are at NO .. 23 Number of MRI Staging cases and 14 Number of Clinical Staging cases are at NI. IS Number of MRI Staging cases and I 0 Number of Clinical Staging cases are at NZ. 2 Number of MRI Staging cases and I Number of Clinical Staging cases are at N3 . P value 0 OS 18 Conclusion: MRI is appropriate method to diagnose and to locate the oral cavity carcinomas along with its extent and staging. Carcinoma of tongue, buccal mucosa having staging T2N1 seems to be more common in the present study. [ABSTRACT FROM AUTHOR]
