A Case of Glomus Tumor Mimicking Neuroendocrine Tumor on 68Ga-DOTATOC PET/CT

A Case of Glomus Tumor Mimicking Neuroendocrine Tumor on 68Ga-DOTATOC PET/CT 68 Ga-DOTA-peptide PET/CT is a valuable tool for diagnosing neuroendocrine tumors (NET). Various tumors and normal human tissue express the somatostatin receptor (SSTR), warranting attention to positive findings on 68 Ga-DOTA-peptide PET/CT. However, overexpression of SSTR in glomus tumors has not yet been reported. Gastric glomus tumors show many similar features of NET and are often misdiagnosed. We present the case of a 61-year-old male with a glomus tumor who underwent distal gastrectomy under the pretense of an NET grade 1 because the nodule showed focal intense uptake on preoperative 68 Ga-DOTATOC PET/CT. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nuclear Medicine and Molecular Imaging Springer Journals

Abstract

68 Ga-DOTA-peptide PET/CT is a valuable tool for diagnosing neuroendocrine tumors (NET). Various tumors and normal human tissue express the somatostatin receptor (SSTR), warranting attention to positive findings on 68 Ga-DOTA-peptide PET/CT. However, overexpression of SSTR in glomus tumors has not yet been reported. Gastric glomus tumors show many similar features of NET and are often misdiagnosed. We present the case of a 61-year-old male with a glomus tumor who underwent distal gastrectomy under the pretense of an NET grade 1 because the nodule showed focal intense uptake on preoperative 68 Ga-DOTATOC PET/CT.
