Neuroendocrine tumor in the kidney is an uncommon neoplasia. The most common neuroendocrine tumor in renal parenchyma is carcinoid (Lane et al. 2007; Hansel et al. 2007). For small cell carcinoma, primary tumor of renal pelvis and metastases should be rule out. Up to 20% of primary renal carcinoids have been reported in “horseshoe” kidneys.

No specific site in the kidney.
Surgical treatment in patients with gross hematuria and abdominal pain
The outcome depends on prognostic...
