Numerous studies on Ultrasonographic (US) findings of Thyroid malignancy have been conducted (1-6). The main pathologic types of thyroid carcinoma are papillary, follicular, medullary, and anaplastic. Papillary and follicular thyroid carcinomas both have an excellent prognosis, with a 20-year survival of 90%-95% and 75%, respectively (7-9). Medullary thyroid carcinoma is more aggressive, with a 10-year survival of 42%-90% (10-11). Anaplastic thyroid carcinoma has an extremely poor prognosis, with a 5-year survival of 5% (10-11). Risk factors for thyroid carcinoma include age of less than 20 years or more than 60 years, a history of neck irradiation, and a family history of thyroid cancer (11.).Thyroid lymphoma, usually of the non-Hodgkin type, is uncommon. It may occur as part of generalized lymphoma or as a primary tumor, usually in the setting of Hashimoto thyroiditis. Metastases to the thyroid are rare and usually originate from primary lung, breast, and renal cell carcinomas. Metastatic disease should be suspected when a solid thyroid nodule is found in a patient with a known non-thyroid malignancy. AIMS & OBJECTIVE: In this study we planned to differentiate different type of thyroid malignancies based on Ultrasonography from one another due their different prognosis. MATERIAL & METHOD: We took 120 patients showing palpable neck masses out of which 40 patients were found to have malignant neoplasm of Thyroid gland. Further differentiation of different type of Thyroid neoplasm was done by Ultrasonography. RESULT: Out of 40 malignant neoplasm, 24 patients had papillary carcinoma and 4 patients had medullary carcinoma Thyroid. Rest 16 patients were kept in other type of thyroid malignancies. CONCLUSION: We concluded our study with the fact that just keeping the patient under category of thyroid neoplasm is just not sufficient, rather we should be able to differentiate each type of thyroid malignancy from one another due to different prognosis of each type.
