To make a correct diagnosis, biopsies of both sites are mandatory. Pathological slides should be compared and immunohistochemical staining should be taken into consideration. In this paper, an unexpected case of synchronous rectal and prostatic carcinomas arising in an 84-year-old male with hematemesis and pelvic pain is reported. These two tumoral components have a distinctive histological appearance. Immunohistochemical evaluation confirmed the diagnosis of these synchronous tumors. This case emphasizes that rectal and prostatic carcinomas can arise simultaneously. In this situation, providing clinicopathological correlation and deciding the necessity of intraoperative consultation in proper time are extremely important.EnglishAll Open Access; Gold Open AccessAged, 80 and overBiopsyCarcinomaHistocytochemistryHumansImmunohistochemistryMaleMicroscopyProstatic NeoplasmsRectal Neoplasmsagedarticlecancer stagingcase reportcomputer assisted tomographydeathepithelium cellhematemesishumanhuman tissueimmunohistochemistrylung edemamalepelvis pain syndromepneumoniaprostate carcinomarectum abdominoperineal resectionrectum biopsyrectum carcinomawedge resectionArticle10.4103/0377-4929.91513
