A case of well controlled renal small cell carcinoma with metastasis treated by intensive therapy

A 18-year-old male visited hospital with macroscopic hematuria. Computed tomography showed slightly enhanced left renal tumor that was uncharacteristic for clear cell carcinoma, and radical nephrectomy was performed. Operative specimen revealed primary small cell carcinoma of the kidney. 18 months after operation, bone metastases were diagnosed. Chemotherapy including cisplatinum, etoposide and bleomycin and external irradiation was performed. This intensive therapy was effective for metastatic lesion. He is still alive for 55 months after diagnosis, and is the best controlled case around the world. To our knowledge, this is the 14th case as primary renal small cell carcinoma in the world literature.
