Papillary renal cell carcinoma (PRCC) complicated by ipsilateral renal tuberculosis (TB) represents an exceptionally rare and complex clinical condition. Renal TB is the most common form of urogenital TB, while PRCC is the most prevalent histological subtype of non-clear cell renal cell carcinoma (RCC). In this study, we present the first reported case of PRCC complicated by ipsilateral renal TB, where the patient exhibited low back pain without hematuria. Initial imaging studies indicated a space-occupying lesion in the left kidney, raising suspicion of renal tumors. Subsequent postoperative pathology, immunohistochemical staining, and tuberculosis PCR results confirmed the diagnosis of PRCC complicated by ipsilateral renal TB.
乳头状肾细胞癌（PRCC）合并同侧肾结核（TB）是一种极为罕见且复杂的临床病症。肾结核是泌尿生殖系统结核最常见的形式，而PRCC是非透明细胞肾细胞癌（RCC）最常见的组织学亚型。在本研究中，我们报告了首例PRCC合并同侧肾结核的病例，该患者表现为腰痛但无血尿。最初的影像学检查显示左肾有占位性病变，怀疑为肾肿瘤。随后的术后病理、免疫组化染色及结核PCR结果证实诊断为PRCC合并同侧肾结核。
