RESUMEN
ABSTRACT: Prostate cancer is the fifth leading cause of death in the male population worldwide. 68 Ga-PSMA PET/CT has proved to be an excellent modality with greater accuracy for nodal and bone/visceral metastases staging than bone scintigraphy and CT scan, with high sensitivity and specificity. Common sites of metastasis include bone (84%), lymph nodes (10.6%), liver (10.2%), lung, and pleura (9.1%); however, metastasis to the skin is quite rare (≤0.36%). The present case demonstrates PSMA-avid perineal metastasis in a patient of prostate cancer postchemoradiotherapy on 68 Ga-PSMA PET/CT scan.

ABSTRACT: 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.
