BACKGROUND
The coexistence of an oncocytoma and a papillary renal cell carcinoma (PRCC) in the same neoplastic mass constitute a collision tumor and is an extremely rare entity. Until now, only six incidentally diagnosed cases have been reported, concerning patients older than 65 years.
CASE REPORT
A 57-year-old man was admitted to the Emergency Department with acute pain and anemia, due to renal hematoma following rupture of such a neoplastic collision mass. The patient underwent an emergency nephrectomy, which revealed a 10.6 cm oncocytoma and a 1.3 cm PRCC. He had an uncomplicated postoperative recovery and remained healthy at the 65-month follow-up, the longest of all previous cases.
CONCLUSION
While prognosis appears favorable, the current report shows that these collision tumors may cause emergency and dangerous medical conditions that deserve prompt treatment. HIPPOKRATIA 2017, 21(2): 105-107.
背景
同一肿瘤块中存在嗜酸细胞瘤和乳头状肾细胞癌（PRCC）构成碰撞瘤，这是一种极其罕见的实体。到目前为止，仅报告了6例偶然诊断的病例，患者年龄均超过65岁。
病例报告
一名57岁男性因这种肿瘤碰撞块破裂后导致肾血肿，伴有急性疼痛和贫血而入住急诊科。患者接受了急诊肾切除术，术中发现一个10.6厘米的嗜酸细胞瘤和一个1.3厘米的PRCC。他术后恢复顺利，在65个月的随访中保持健康，这是所有既往病例中随访时间最长的。
结论
虽然预后似乎良好，但本报告表明，这些碰撞瘤可能导致紧急且危险的医疗状况，值得及时治疗。《希波克拉底》2017年，21(2): 105 - 107。
