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. Case presentation 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.
