Abstract

Carcinoid tumors are low-grade malignant tumors that arise from neuroendocrine cells. Primary renal carcinoid tumors are extremely uncommon. A 63-year-old woman presented with a right abdominal mass and fever. Abdominal computed tomography demonstrated a mass in the right kidney; the mass measured 120 mm in diameter and showed hemorrhage. The patient underwent an uneventful right radical nephrectomy, and histological appearance was typical of carcinoid tumor. Immunohistochemistry demonstrated strong cytoplasmic labeling for neuron-specific enolase and synaptophysin. Additional examinations of the gastrointestinal tract did not show any evidence of carcinoid tumors. The patient remains free from disease recurrence at 8 months after the operation. The prognosis for primary renal carcinoid tumor is relatively optimistic. Complete surgical excision is the only recommended treatment for localized renal carcinoid tumor.
