In order to diagnose the problem a colonoscopy was conducted in which the diagnosis was a tumoral mass in Rectum that was adjucent to Anus. No other gross lesion was seen up to Cecum (Figure 1). In order to determine the stage of this tumor an Endoscopic ultrasound (EUS) was performed. In the sonography's report a T1N0 low rectum malignancy was indicated (Figure 2). A biopsy was taken too.
