Unusual Presentation of Solitary Penile Metastasis of Prostate Cancer on 68Ga-PSMA PET/CT

Clin Nucl Med. 2023 Dec 22. doi: 10.1097/RLU.0000000000005002. Online ahead of print.ABSTRACTA 75-year-old patient was referred with biochemical recurrence for prostate cancer. The patient underwent 68Ga-PSMA (prostate-specific membrane antigen) PET/CT scan, which revealed a focal PSMA activity in the proximal left lateral penile margin. Although a subsequent ultrasound did not identify the abnormality, MRI pelvis revealed a 10-mm lesion in the left proximal corpus cavernosum. This lesion was consistent with metastatic acinar adenocarcinoma of the prostate on postresection histopathology. This unusual presentation of asymptomatic, histopathology-proven, penile solitary metastases was documented 3 years after robotic-assisted laparoscopic prostatectomy and pelvic external beam radiotherapy.PMID:38141008 | DOI:10.1097/RLU.0000000000005002
