Primary Carcinoid Tumor of the Testis / 대한남성과학회지

Primary testicular carcinoid is a rare disease, accounting for less than 1% of all testicular neoplasms, with the potential for distant metastasis. We report a case of primary testicular carcinoid in a 44-year-old-man who presented with a painless, palpable mass in the left testis. Preoperative testicular ultrasound examination revealed a solid mass. Radical orchiectomy was performed, and pathologic examination showed a carcinoid tumor confined to the testis. There was no evidence of carcinoid syndrome, and a 24-hour urinary 5-HIAA assay was normal. Abdominopelvic CT scan and gastrointestinal contrast study showed no evidence of carcinoid in other organ. At 12 months postoperatively, the patient was without evidence of tumor recurrence.
