BACKGROUND Although metastatic adenocarcinoma of the ileum is not uncommon,solitary metastasis to the seminal vesicle has not been reported.We report a patient with recurrent hematospermia diagnosed with metastasis to the seminal vesicle following ileal adenocarcinoma resection,his subsequent management and outcome.CASE SUMMARY A 46-year-old man presented with recurrent episodes of painless hematospermia.This was not associated with any lower urinary tract symptoms.He had a past medical history of ileal tumor at the terminal ileum with solitary mesenteric lymph node metastasis on presentation,and underwent partial ileectomy and lymphadenectomy 4 years ago.Subsequent investigations included positronemission tomography and computed tomography imaging confirmed the very unusual diagnosis of a solitary tumor at the left seminal vesicle.Laparoscopic leftsided vesiculectomy was carried out.Histological analysis with immunohistochemistry showed that CDX-2 was positive and CK7 was negative,and the appearance was consistent with the diagnosis of recurrent metastatic adenocarcinoma of his previously treated intestine primary.The patient had an uneventful post-operative recovery.He received adjuvant chemoradiotherapy following surgery.He remained asymptomatic until he developed multiple bone and pulmonary metastases one year after surgery.CONCLUSION Clinicians should be aware of hematospermia as the first symptom of metastatic recurrence in patients with a history of ileal adenocarcinoma.
