Association between gefitinib and hemorrhagic cystitis and severely contracted bladder: a case report

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.
