We presented the clinical data of one patient with renal cell carcinoma associated with idiopathic thrombocytopenic purpura in this case report. We reported a 56-year-old man who presented with petechiae and ecchymoses. Laboratory studies showed the platelet count of 2 × 10⁹/L and an abdominal computed tomography (CT) scan revealed tumors in the right renal. There were purpura on the legs and cough without abdominal pain and melena at this time. Idiopathic thrombocytopenic purpura was diagnosed according to the clinical symptoms and laboratory test. The patient received radical nephrectomy for renal carcinoma, and his idiopathic thrombocytopenic purpura was cured after the surgery. Pathological biopsy confirmed it was renal clear cell carcinoma. The patient has been followed up for more than 3 months after surgery, and the ecchymoses had not been recurred and the patient’s thrombocytopenia was recovered. Idiopathic thrombocytopenic purpura associated with kidney cancer is rare. The patient in this case report was treated with radical nephrectomy, and the effectiveness of idiopathic thrombocytopenic purpura was satisfactory.

在此病例报告中，我们介绍了一名伴有特发性血小板减少性紫癜的肾细胞癌患者的临床数据。我们报道了一个56岁的男人，他患有瘀斑和瘀斑。实验室研究显示血小板计数为2×10 ⁹/ L和腹部CT扫描显示右肾中有肿瘤。腿部有紫癜，咳嗽时没有腹痛和黑便。根据临床症状和实验室检查诊断为特发性血小板减少性紫癜。该患者因肾癌接受了根治性肾切除术，其特发性血小板减少性紫癜在手术后得以治愈。病理活检证实为肾透明细胞癌。手术后对该患者进行了3个多月的随访，并且瘀斑未复发，患者的血小板减少症已恢复。与肾癌相关的特发性血小板减少性紫癜很少见。本例报告中的患者接受了根治性肾切除术治疗，
