Abstract
An extrapulmonary neuroendocrine tumor arising in the prostate gland has been described in several case series; however, pure and primary prostatic neuroendocrine tumors are very rare, their biologic behavior is not yet well known, and there are only a few reports in the literature describing the clinical features and management of this neoplasm. This article presents the clinicopathologic findings of 2 patients presenting with this disease. The published reports of primary pure neuroendocrine prostate tumors are discussed.
