Abstract: Granular cell tumor presenting as a thyroid mass is very rare. It may arise from the thyroid gland or from the tissues/organs adjacent to the thyroid gland. It may cytologically mimick other common thyroid tumors. The accurate evaluation of these tumors may be important for management. We describe a granular cell tumor arising from the tissue adjacent to the thyroid gland and with multiple organ/tissue involvement in a 27-year-old woman with an initial presentation of a thyroid mass. The diagnosis was made preoperatively by fine needle aspiration and immunocytochemial stains in conjunction with radiological examination. To our knowledge, there is no previous report of such cases in the literature and the importance of fine needle aspiration in conjunction with radiologic examination in the evaluation of granular cell tumor presenting as a thyroid mass has not been well addressed.
