Hashimoto's thyroiditis is an autoimmune chronic inflammatory disease of the thyroid gland. It is the second most common thyroid lesion diagnosed by cytology, after goiter. MATERIAL AND METHOD: The Study was conducted in the department of pathology. All aspiration were done by cytopathologists to ensure representative sampling.Using sterile precautions FNAC was performed using nonaspiration or aspiration techniques by 23 G needle with 10 ml syringe. The smears were either air dried or alcohol fixed (95%). Air dried smears were stained by the Gimsa stain and alcohol fixed by Hematoxiline and eosin. RESULT: We included 75 cases of thyroiditis. 4 cases were male and 71 were female with female to male ratio of 17.75:1. The age ranged from 8 to 65years with a median age of 36.5 years. 75 csaes of thyroiditis have been evaluated on the basis of cytomorphological criteria, Biochemical and clinical findings of patients. CONCLUSION: FNAC is a safe, reliable, cost effective and time saving method in the diagnosis of thyroiditis.

Thyroid nodules the main indication for FNAC, and the goal of this diagnostic procedure is to detect thyroid neoplasm for surgical resection and to identify non-neoplastic lesions that may be managed conservatively. MATERIAL AND METHODThree hundred and fourteen patients with thyroid nodules diagnosed on physical examination underwent fine-needle aspiration with 23-gauge needle and 10ml syringe. FNAC results were classified into non-neoplastic lesion and neoplastic lesion for diagnosis. RESULT AND ANALYSISWe included 314 cases; 37 were male and 277 were female with female-to-male ratio of 7.48:1. The age ranged from 8 to 87 years with a median age of 47.5 years. Maximum number of patients were found in age group of 41-50 years). In the present study we found 285(90.76%) non-neoplastic lesion and 29(9.23%) neoplastic lesions. Out of 285 non-neoplastic lesion, most commonly encountered were colloid goiter 178(56.68%) and second most common thyroiditis 100(31.84%). Out of 314,29(9.23%) neoplastic lesions, most commonly encountered neoplasm were papillary carcinoma 14(4.45%) followed by 9(2.86%) follicular neoplasm, Hurthle cell neoplasm 2(0.63%), medullary carcinoma 4(1.27%). AIMS AND OBJECTIVES To study the distribution of various thyroid lesions among the age and sex groups.  To study the cytomorphological, clinical and biochemical correlation. CONCLUSIONClinical features and serum findings when used alone to diagnose thyroid lesion, diagnosis will be missed in many cases.
