Bilateral asynchronous metastatic carcinoid tumor of the testis.

Carcinoid tumor of the testis represents only 0.23% of all testicular malignancies. We report the first case of bilateral asynchronous carcinoid tumor of the testis with a primary site in the small bowel. A 49-year-old man presented with several months of painless enlargement of the left testis. Orchiectomy revealed carcinoid tumor. The patient presented to the emergency room 2 weeks later and was found to have small bowel obstruction due to an ileal mass. The resected mass was the primary source of the carcinoid tumor. Four years later, examination revealed carcinoid tumor in his remaining testis.
