Abstract

Primary carcinoid tumors of the testis are a rare entity comprising less than 1% of all testicular neoplasms. Their presence should be considered particularly when evaluating a testicular lesion in an older male patient. Immunohistochemical studies may aid in diagnosis and radiographic evaluation is important to rule out metastatic origin. Primary carcinoid tumors of the testis are associated with an excellent prognosis; however, surveillance is important given rare reports of delayed metastases.
