Abstract
Sarcomatoid carcinoma is a high‑grade malignant neoplasm which exhibits morphological and/or immunohistochemical evidence of bidirectional epithelial and mesenchymal differentiation. Sarcomatoid carcinoma occurring in the upper urinary tract is rare. The present study reports a case of primary sarcomatoid carcinoma of the renal pelvis. A 49‑year‑old female patient was admitted to Beijing Chao‑Yang Hospital for experiencing two weeks of intermittent hematuria. A computed tomography scan revealed a mass of 2 cm in diameter in the left renal pelvis. A retroperitoneoscopic nephroureterectomy combined with a bladder cuff excision was performed, and the final pathological diagnosis was sarcomatoid carcinoma of the renal pelvis. The patient did not receive systemic chemotherapy and radiotherapy. Regular follow‑up was performed for 30 months, and there was no evidence of tumor local recurrence or distant metastasis.
