Pelvicalyceal Squamous Cell Carcinoma: Incidental Diagnosis With Liver Metastasis on Follow Up.

Primary squamous cell carcinoma (SCC) of the renal pelvis is a rare malignancy. We report a case of a 43-year-old male presenting with stones and a non-functioning kidney. Incidental SCC was diagnosed histopathologically on nephrectomy. The patient then returned with metastasis to the liver after one year. Nephrolithiasis is the most important risk factor implicated in renal SCC; hence, awareness of this rare entity in a patient of long-standing nephrolithiasis is important.
