Abstract
BACKGROUND
Seminal vesicle metastasis from colorectal cancer (CRC) is extremely rare and poses diagnostic and therapeutic challenges. Limited cases have been reported, and its clinical characteristics remain poorly understood.
CASE SUMMARY
We report a case of synchronous seminal vesicle metastasis originating from rectosigmoid adenocarcinoma. The diagnosis was established through imaging and confirmed by histopathology. The patient underwent surgical resection followed by adjuvant chemotherapy and achieved favorable outcomes with no evidence of recurrence during a two-year follow-up period.
CONCLUSION
Seminal vesicle metastasis should be considered in atypical cases of CRC.
Core Tip: Seminal vesicle metastasis from colorectal cancer is extremely rare and difficult to diagnose. We report a case of synchronous metastasis from rectosigmoid adenocarcinoma confirmed by imaging and histopathology, with favorable long-term outcomes. This case highlights the importance of distinguishing distant metastasis from direct invasion and supports comprehensive treatment strategies.
