title: [Penile metastasis from rectal carcinoma: a case report and literature review].
abstract: OBJECTIVE
  To improve the diagnosis and treatment of penile metastasis from rectal carcinoma.
  
  
  METHODS
  We reported a case of penile metastasis secondary to rectal adenocarcinoma, reviewed the relevant literature, and discussed the common origins, clinical features, pathogenic mechanisms, diagnosis and treatment of this disease.
  
  
  RESULTS
  The patient was a 54-year-old male, with metastatic penile tumors secondary to rectal adenocarcinoma, with serious adhesion to the surrounding tissue and metastasis to the liver. As treatment, we performed colostomy to relieve voiding difficulty, followed by combination chemotherapy with oxaliplatin, 5-fluorouracil, and levofolinate. The patient died 10 months later as a result of systemic failure.
  
  
  CONCLUSIONS
  Penile metastatic malignancy has a poor prognosis. Early diagnosis and combined and individualized therapies may improve the quality of life, relieve pain and prolong the life of the patient.
