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.
We present our experience of a patient with metastatic renal carcinoid from the gastrointestinal tract.
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.

我们考虑该患者的肾脏类癌为转移性，依据是其病理发现。该患者曾患有直肠类癌肝转移，有肝转移病史。
