Abstract
Prostate adenocarcinoma with testicular metastasis is rare, present in up to 4% of autopsy diagnoses, and presents symptomatically in less than 0.5% of cases. We report an unusual case of a 55-year-old male who developed a symptomatic testicular metastasis from primary prostate cancer 4 years after initial diagnosis of metastatic castrate-sensitive prostate cancer with nodal and bone-only involvement. The patient had orchidectomy, histologically confirming the metastasis and revealing sparing of the spermatic cord. Prior treatment for his metastatic castrate-sensitive prostate cancer had included androgen deprivation therapy and upfront docetaxel chemotherapy. He had received palliative radiotherapy for symptomatic bone metastasis and managed on enzalutamide for castrate-resistant disease for the preceding 22 months with ongoing PSA response at the time of diagnosis of new testicular metastasis, with a further significant PSA response following his “testicular metastasectomy.” At the time of diagnosis of testicular metastasis, he did not have any evidence of other visceral metastases, and his metastatic disease otherwise remained radiologically stable. We describe his disease course, treatment and outline the rare nature of his case of testicular metastasis from prostate cancer.
