Primary squamous cell carcinoma of the renal pelvis is an extremely rare entity representing only 0.5% to 0.8% of all urothelial malignancies. Clinical suspicion is difficult due to its rarity and inconclusive clinical and radiological features. A 67-year-old lady with a history of hematuria presented to the hospital in a state of shock. After proper workup, a mass with heterogeneous density was seen in the lower portion of the left kidney. After radical nephrectomy, histopathological examination revealed squamous cell carcinoma of renal pelvis. Squamous Cell Carcinoma should be suspected in a patient with a long history of renal calculus and associated mass in non-functioning kidney. Keywords: Calculus; mass; pelvis; squamous cell carcinoma.
肾盂原发性鳞状细胞癌极为罕见，仅占所有尿路上皮恶性肿瘤的 0.5%至 0.8%。由于其罕见性和临床及影像学特征不明确，临床怀疑较为困难。一位 67 岁的女性患者因血尿就诊，就诊时已处于休克状态。经过适当的检查，在左肾下部可见混杂密度肿块。行根治性肾切除术，组织病理学检查显示肾盂鳞状细胞癌。对于有长期肾结石病史和无功能肾伴肿块的患者，应怀疑鳞状细胞癌。关键词：结石；肿块；肾盂；鳞状细胞癌。
