Primary renal neuroendocrine tumors are exceedingly rare neoplasms, with fewer than 100 cases reported in the literature. We report the case of a 45-year-old male with an eight-month history of intermittent gross hematuria. Imaging revealed a large Bosniak 3 renal cyst with inconclusive solid components. Laparoscopic radical nephrectomy was performed uneventfully. Histopathological analysis confirmed a well-differentiated neuroendocrine tumor, grade II, with a Ki-67 index of 15 % and mitotic count of 1/2 mm². The patient remains under active surveillance with no recurrence. This case emphasizes the diagnostic challenges and the role of a multidisciplinary approach in the management of rare renal tumors.
