title: [Rectal hemorrhage as the first manifestation of prostatic carcinoma].
abstract: OBJECTIVE
  An uncommon case of prostatic carcinoma presenting as rectal hemorrhage is described. The diagnostic and therapeutic aspects are discussed and the importance of distinguishing this condition from rectal carcinoma is underscored.
  
  
  RESULTS
  The clinical features of a patient with invasive prostatic carcinoma presenting as rectal hemorrhage are described.
  
  
  CONCLUSIONS
  Rectal involvement by invasive prostatic carcinoma should be suspected in patients consulting for a rectal pathology, particularly if the patient has a previous history of prostatism or carcinoma of the prostate. The incidence of rectal involvement by prostatic carcinoma has been reported to range from 1 to 11%.
