Abstract
Gastrin-releasing peptide receptor (GRPR) is a promising agent for imaging and development of theranostic radioligands in estrogen receptor (ER)-positive luminal type breast cancer (BC) and may show expression not only in primary malignant lesions but also in lymph node metastases and distant organ metastases. We would like to present a lesion diagnosed as benign apocrine metaplasia in a 45-year-old woman diagnosed with BC, which was negative in 68 Ga-DOTA-Bombesin PET-CT and false positive in 18 F-FDG PET-CT imaging, within the scope of the ongoing study.
