A patient with a history of a parathyroid adenoma, papillary thyroid carcinoma, and acoustic neuroma was suspected of harboring a NET based upon 2 circulating tumor nucleic acid tests that used different methodology and a positive <sup>68</sup>gallium-dodecanetetraacetic acid-tyrosine-3-octreotate (<sup>68</sup>Ga-DOTATATE) scan corresponding to a 2.2-cm right gluteal mass, which was found to be an intramuscular hemangioma expressing somatostatin receptor 2 subtype (SSTR2) in the endothelial cells. The gene discussed is SSTR2; the disease is thyroid gland papillary carcinoma.
