We present a case of a 58-year-old man hospitalized because of gangrene of the penis and scrotum, after radiochemotherapy for rectal cancer. At the time of the admission the patient presented with extensive gangrene with necrosis affecting the scrotum and the penis. During the first day of hospitalization the patient was operated. Due to the progress of the disease he had to be operated again. The status of the patient, which initially was very bad, was gradually improving. He was discharged from the hospital after 59 days in a good general state with good wound healing.
