Solitary Penile Metastasis from Prostate Cancer on F-Prostate-Specific Membrane Antigen Positron Emission Tomography/Computed Tomography.

We report a case of a 66-year-old man with prostate cancer who underwent F-prostate-specific membrane antigen positron emission tomography/computed tomography for baseline staging that revealed primary lesion in prostate gland along with a solitary metastatic deposit in the penile shaft. Penile metastasis is rare and usually associated with widespread metastatic disease. Solitary penile metastasis is even rarer and can present as a unifocal, multifocal, or diffuse lesion.
