ABSTRACT
PURPOSE: Hormone-refractory prostate cancer (PCa) has a high incidence of metastasis with common secondary site locations. Our case report describes a rare metastatic site of PCa infiltrating bilateral testicles in the absence of definitive radiologic evidence. MATERIALS AND METHODS: Following the patient's consent and IRB exemption, we report the clinical, radiological, and pathological presentation of the patient treated at our institution. We also conducted an inclusive literature review of PCa with bilateral testicular metastases. RESULTS: Our patient is a 54-year-old male who presented to the emergency room with lower urinary tract symptoms and failure to void. A full workup including digital rectal examination, PSA (580 ng/ml), and a transrectal ultrasound (TRUS) biopsy performed afterward revealed an adenocarcinoma of the prostate. The metastatic workup at presentation was negative. After failure to comply with treatment guidelines, the patient was referred back to us with bilateral testicular masses. Without clear evidence of the origin of the masses, bilateral orchiectomy was performed, and pathological analysis confirmed it was metastatic prostate adenocarcinoma. Post-orchiectomy, the patient was again lost to follow up. Three years later the patient returns and placed in palliative care. CONCLUSIONS: This case report highlights that PCa can have a highly variable course and progression can occur in the absence of adherence to treatment. Any evidence of disease relapse and clinical suspicion of metastasis should be investigated, especially in patients with advanced and metastatic disease or poor adherence to surveillance protocol.
