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 ${\times}$ 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.

현재까지 우리나라에서는 본 증례를 포함해 아주 적은 수의 원발성 신유암종이 보고되었으며, 치료 및 임상적 특성 예후에 대해 아직 밝혀지지 않은 부분이 많으므로 지속적인 증례 보고 및 연구가 필요할 것으로 생각된다.
