Popis: Purpose: To assess the prevalence of intratubular germ cell neoplasia (ITGCN) in patients with concurrent testis tumor and its correlation with histologic features and serum tumor markers. Materials and Methods: From 2003 to 2015, 179 patients underwent radical orchiectomy due to testicular mass. Tissue specimens were evaluated by an expert uro-pathologist using immunohistochemistry (IHC) staining, in addition to light microscopy, to identify presence of ITGCN. Patients’ demographic characteristics, histologic subtypes, pathologic stage of tumor and serum tumor markers were gathered and analyzed. Results: Eighty-five out of 179 patients (47.5%) had concomitant ITGCN according to IHC staining. There was not statistically significant difference in histologic type, histologic components, cryptorchidism, and lymphovascular invasion between the 2 groups (p=0.151, p=0.11, p=0.233, p=0.413, and p=0.14, respectively). The prevalence of ITGCN was significantly higher in patients with stage T2 and T3 of tumor than those with stage T1. Elevated serum alpha feto protein level is much common in patients with ITGCN (p
