特発性血小板減少性紫斑病を合併した腎細胞癌1例の臨床データを報告した。症例は56歳の男性で，点状出血とエクチモーゼを呈した．臨床検査では血小板数が2×10/L，腹部CT検査では右腎に腫瘍が認められた．この時、腹痛を伴わない足の紫斑と咳があり、メレナがあった。特発性血小板減少性紫斑病と診断された．腎癌の根治的腎摘出術を受け，術後に特発性血小板減少性紫斑病は治癒した．病理生検の結果、腎清澄細胞癌であることが確認された。術後3ヶ月以上経過観察したところ、エクシモーズは再発せず、血小板減少も回復していた。腎癌に伴う特発性血小板減少性紫斑病はまれである。本症例は根治的腎摘出術で治療し、特発性血小板減少性紫斑病の効果は良好であった。

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 × 10/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.
