We report a rare case of granular cell tumor (GCT) arising within the thyroid parenchyma. The differential diagnosis of GCT in thyroid includes all oncocytic/Hürthle cell lesions of the thyroid, medullary carcinoma and metastasis. The classic histomorphologic features and immunohistochemistry are helpful in arriving at the correct diagnosis.
