Solitary recurrence of prostate cancer surrounded by seminal vesicle/vas deferens‐like epithelium

INTRODUCTION: Clinical recurrence of prostate cancer after curative treatment with a limited number of metastases is often termed as oligorecurrence. We report a case of solitary recurrence of prostate cancer surrounded by epithelium of the seminal vesicle or vas deferens. CASE PRESENTATION: A 54‐year‐old man diagnosed with localized prostate cancer underwent radiation therapy. Six years later, imaging studies detected a solitary recurrence. We performed metastasectomy, and histopathological examination revealed the metastatic lesion surrounded by the epithelium of the seminal vesicle or vas deferens. Surgical resection achieved a complete biochemical response. CONCLUSION: We presented with a case of prostate cancer metastasis surrounded by the epithelium of the seminal vesicle or vas deferens.
