Abstract

Hyalinizing trabecular tumor (HTT), a type of thyroid lesion, was first reported by Carney in 1987 and has since been reported continuously. Due to its histological non-specificity, HTT can be misdiagnosed as papillary thyroid cancer or medullary thyroid cancer. For this reason, over treatment might occur; for example, total thyroidectomy and lymphadenectomy. Diagnosis and treatment is a challenge because there is still controversy regarding HTT characters. We report on two cases. One patient was a 48-year-old female and the other was a 46-year-old female. Both patients complained of a thyroid mass and were diagnosed as HTT.
