We report a rare case of squamous cell carcinoma (SCC) in bladder diverticulum producing granulocyte colony stimulating factor (G-CSF). A 59-year-old man complaining of hematuria and right hip pain was admitted with a large cancer in the bladder diverticulum. His laboratory data showed leukocytosis of 20, 100/ μ l (neutrophils : 92%) with an elevated G-CSF of 76. 6 pg/ml in the peripheral blood. After neoadjuvant chemotherapy (gemcitabine and cisplatin), radical cystectomy was performed to normalize serum leukocytosis and G-CSF. Histopathological diagnosis was G-CSF-producing SCC pT4N0. He appeared with left pelvic lymph node metastasis and right pulmonary metastasis 3 months after surgery. Therefore, he was treated with four courses of combination chemotherapy (paclitaxel, ifosfamide and nedaplatin) and radiation therapy at left pelvic lymph node metastasis. Computed tomography after these treatments showed complete response. The patient is alive with no evidence of tumor 16 months after surgery.
