We report the case of a 51-year-old Thai female presented with right abdominal mass with pain and anemia. The radiographic findings showed ruptured renal mass. She underwent radical nephrectomy and the pathological report was malignant neuroendocrine tumor. Palliative chemotherapy was administered. The patient passed away three months after the operation. Renal neuroendocrine tumors are rare. Moreover, ruptured renal tumors are very rare. They are usually considered to be angiomyolipoma or renal cell carcinoma. Poor differentiation and rupture at presentation are aggressive features of tumors. To the best of our knowledge, this is the first case report of ruptured renal malignant neuroendocrine tumor.
