Renal cyst is a common benign disease which is rare to progress from simple renal cyst to renal cell carcinoma.
A 62-year-old woman who suffered a simple renal cyst for over 20 years complained intermittent lumbar in recent 2 years. At her latest admission, the cyst lesion displayed enhancement in the cystic wall by CT scan and cystic to partially solid change by ultrasound, so we did a partial nephrectomy and found that the cystic lesion had become a cyst-solid transition. The pathology turned out to be renal clear cell carcinoma.
Although the canceration of a renal cyst is a small probability event, patients with a long history of a cyst, especially those with symptoms, need to seek for medical treatment in time, and if necessary, lesion biopsy or resection may be under consideration.
肾囊肿是一种常见的良性疾病，从单纯性肾囊肿发展为肾细胞癌的情况较为罕见。
一名62岁女性，患有单纯性肾囊肿20多年，近2年来间歇性腰痛。在她最近一次入院时，CT扫描显示囊肿壁有强化，超声显示囊肿呈囊实性改变，因此我们进行了部分肾切除术，发现囊性病变已转变为囊实性。病理结果为肾透明细胞癌。
虽然肾囊肿癌变是小概率事件，但囊肿病史较长的患者，尤其是有症状者，需要及时就医，必要时可考虑进行病变活检或切除。
