Special pathological type of upper urinary tract malignancy-squamous cell carcinoma of the renal pelvis: A case report and literature review.

To investigate the clinnical features for squamous cell carcinoma (SCC) of the renal pelvis. We analyzed the medical records of a patient diagnosed with SCC of the renal pelvis and performed a literature review. SCC of the renal pelvis is a rare pathological type of upper urinary tract malignancy with nonspecific clinical features. Its diagnosis relies on postoperative pathology and immunohistochemistry. Radical resection is the gold standard for treatment. Patients with long-term urothelial irritation should be regularly screened, pathogenic factors should be proactively addressed, and vigilance should be maintained to prevent the development of SCC.
