The combination of more than one thyroid carcinoma variants has been reported very rarely which includes combination of follicular carcinoma with papillary carcinoma, medullary carcinoma with follicular carcinoma and anaplastic, and follicular and papillary carcinoma with follicular adenoma. We report another combination of Hurthle cell adenoma with incidental occurrence of micropapillary carcinoma adding to the group of collision tumors in thyroid.
