Primary Thyroid Tuberculosis

The connection of the thyroid by tuberculosis (TB) is uncommon. Hypothyroidism caused by tissue damage is an exceptionally rare report. The  aim was to statement a patient with primary thyroid TB emphasizing the importance of diagnosis, despite the rarity of the occurrence. Tuberculosis of the thyroid gland is a very rare disease. The incidence of extra pulmonary tuberculosis has been showing a progressive increase in the recent years. We present three cases of primary thyroid tuberculosis. Methods. Two cases were diagnosed on the basis of fine-needle aspiration cytology (FNAC), as they presented with thyroid nodule. The third case was diagnosed on histopathology as the patient underwent total thyroidectomy for the left-side nodule which was a follicular lesion on FNAC. Tuberculosis was diagnosed on the other lobe. Results. All three patients were given antituberculous treatment for nine months, and their nodular lesions completely resolved after treatment
