68 Ga-PSMA-11 Uptake in a Large Fibroadenoma in a Male Axillary Accessory Breast.

Prostate-specific membrane antigen PET imaging has revolutionized the role of prostate cancer diagnosis and management, with very high sensitivity and specificity. To prevent misdiagnosis and for accurate therapy planning, prostate-specific membrane antigen (PSMA) uptake in nonprostatic diseases needs to be recognized correctly. Besides the physiological PSMA expression, 68 Ga-PSMA-11 uptake has been mentioned in multiple oncological and nononcological lesions. The present case report exhibits 68 Ga-PSMA-11 uptake in fibroadenoma in a male accessory breast in the right axillary region.
