Primary Adenocarcinoma of the Renal Pelvis: A Case Report and Review of the Literature

原發性腎盂腺癌:病例報告與文獻回顧

摘要


腎盂腫瘤,佔所有腎臟惡性腫瘤約7-8%。大多數這類的腫瘤源起於泌尿上皮、其中最常見的型態為泌尿上皮瘤,其次為鱗狀細胞癌。原發性腎盂腺癌是一種極為罕見的類型,在文獻中,只有少數的個案被報導。其發生原因可能是因為泌尿道結石引發長期的泌尿道阻塞、感染、以及慢性的刺激,導致腎盂移形上皮化生成腺狀上皮,最後再轉變成惡性腫瘤。在此,我們報導一位罹患原發性腎盂腺癌的50歲女性,患者本身有腎臟結石、末期腎臟疾病的病史,並展現其腫瘤於影像學上的表現。

Neoplasms of the renal pelvis account for approximately 7-8% of all renal malignancies, and most such neoplasms are urothelial in origin. Among these malignancies, the most common type is urothelial carcinoma, followed by squamous cell carcinoma. Primary adenocarcinoma of the renal pelvis is an extremely rare type, with only a few case reports in the literature. It may occur as a result of metaplasia of the renal pelvic transitional epithelium into glandular epithelium due to longstanding obstruction and infection and chronic irritation by urolithiasis, which then undergoes a malignant transformation. Herein, we report a case and the image findings of primary adenocarcinoma of the renal pelvis in a 50-year-old woman with history of renal calculi and end-stage renal disease.
