Abstract:
Carcinoid tumors are low-grade malignant tumors arising from neuroendocrine cells. Primary renal carcinoid tumor is very rare due to the absence of neuroendocrine cells in the kidney and ureter. Therefore, little is known about the management and prognosis of renal carcinoid. Here, we report a case of a primary renal carcinoid tumor arising from a normal kidney in a 21-year-old man. He presented with a left renal mass, which was found accidentally. Abdominal computed tomography (CT) showed a 5.5 x 5.0-cm cystic mass with calcification. We suspected a cystic renal cell carcinoma and performed a laparoscopic radical nephrectomy. However, the histology revealed a well-differentiated neuroendocrine tumor. We concluded that it was a primary renal carcinoid tumor with no distant metastasis and did not administer chemotherapy or radiation therapy. He is recurrence-free after 8 months.
