Core Tip

Core tip: Prostatic neuroendocrine carcinoma (PNEC) comprised 0.5%-2% of all prostate carcinoma, commonly presents with lymph node, bone, or organ metastases and has a poor prognosis when a definite diagnosis was given in clinic. Our cases and literature suggest it is usually insufficient that the prostate is examined by ultrasound and computed tomography (CT), or prostate specific antigen in serum for the symptomatic and/or with high risk factors crowd. Emphasizing the complementary roles of the malignant signs in diffusion-weighted image, early enhancement in CT or magnetic resonance imaging, self-contradictory clinical appearance and laboratory results can help achieving the accurate diagnosis of PNEC, maybe in early stage.
