RESUMO
Testicular carcinoids are very rare and account for less than 1% of all testicular neoplasms. They may present as primary testicular tumors or secondary tumors from extratesticular sources. We report a case of a secondary testicular carcinoid occurring 10 years after surgical treatment of an appendiceal carcinoid. The patient underwent radical orchiectomy and at 24 months of follow-up had no evidence of metastases elsewhere. Because secondary carcinoids have a worse clinical course and prognosis than primary tumors, metastatic disease should be excluded before the tumor is identified as a primary. Long-term follow-up is necessary for patients with carcinoid tumor owing to its indolent course and the risk of metastasis several years after treatment of the primary.
