title: A rare case of metastatic renal carcinoid.
abstract: BACKGROUND
  Carcinoid is an endocrine cell tumor with low-grade atypia, which is generally a low-grade malignant cancer with a good prognosis. Metastatic renal carcinoid is even rarer than primary carcinoids.
  
  
  METHODS
  We present our experience of a patient with metastatic renal carcinoid from the gastrointestinal tract.
  
  
  CONCLUSIONS
  The carcinoid tumor of the kidney in our patient, who had a history of liver metastasis from rectal carcinoid, was considered metastatic based on the pathological findings.
