Iodine Avid Papillary Thyroid Cancer Showing PSMA-Expression in 68Ga-PSMA Ligand PET/CT

Introduction
Prostate-specific membrane antigen (PSMA) is a type II transmembrane glycoprotein highly expressed by prostate cancer. Ga-68-labeled PSMA analogues have been recently used for PET/CT imaging. PSMA expression has been detected in neovasculature of various solid tumors including thyroid cancers. The enzymatic function of PSMA is currently not completely understood. However, high expression of PSMA in thyroid cancers is correlated with poor differentiation and has been shown in mainly anaplastic and follicular types [1], [3], [5]. To date, only one case reported PSMA expression in a patient with radioiodine refractory papillary thyroid cancer [2]. Here we report the first case of intensive PSMA expression in iodine-avid, newly diagnosed papillary thyroid cancer. This case simultaneously demonstrates an autonomous thyroid nodule with no PSMA expression.
