Xanthogranulomatous pyelonephritis (XGP) and primary renal squamous cell carcinoma (SCC) are both rare conditions that can present very similarly in a patient with renal staghorn calculi. We report a case of a 54-year-old male who presented with fatigue, vomiting and significant acute weight loss. The patient was initially believed to have XGP, but was ultimately diagnosed with both XGP and primary renal SCC. This case report and literature review is meant to elucidate the similarities and differences between XGP and primary renal SCC as both can be diagnostically challenging.

黄色肉芽肿性肾盂肾炎（XGP）和原发性肾鳞状细胞癌（SCC）都是罕见疾病，在患有肾鹿角形结石的患者中表现可能非常相似。我们报告一例54岁男性病例，该患者出现疲劳、呕吐和明显的急性体重减轻。患者最初被认为患有XGP，但最终被诊断为同时患有XGP和原发性肾SCC。本病例报告和文献综述旨在阐明XGP和原发性肾SCC之间的异同，因为两者在诊断上都具有挑战性。
