Abstract
BACKGROUND: Primary renal carcinoid is extremely rare and there are few reports on the natural history of the disease. CASE PRESENTATION: A 68-year-old male with a right renal mass who lost to follow-up for ten years has been presented. His only complaint was a mild flank pain. Upon admission to the hospital for his renal mass, he underwent a right radical nephrectomy and pathological examination revealed the diagnosis of primary renal carcinoid. CONCLUSIONS: In light of the presented case, primary renal carcinoma may have a prolonged natural history with no distant metastasis and any change in the quality of life of the patient.
