title: Clear cell variant of follicular thyroid carcinoma with normal thyroid-stimulating hormone value: a case report.
abstract: BACKGROUND
  Clear cell carcinomas of the thyroid gland with normal thyroid-stimulating hormone value are very rare, but clear cell changes are described in most reported cases of thyroidal lesions.
  
  
  METHODS
  In this report, we describe the case of a 50-year-old Caucasian woman with a normal thyroid-stimulating hormone level who underwent surgery to treat a multi-nodular goiter. The pathology was a clear cell variant of follicular thyroid carcinoma. The tumor was 1cm in diameter and consisted of pure clear cells.
  
  
  CONCLUSIONS
  Clear cell variants of follicular thyroid carcinoma are rarely seen, especially it is misdiagnosed with metastatic renal cell carcinoma. In this report, we describe the case of a patient with a clear cell variant of follicular thyroid carcinoma with an interesting pathology.
