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.
Keywords: metastasis‐directed therapy; oligorecurrence; prostate cancer; seminal vesicle; vas deferens.
