title: [Bladder carcinoma producing granulocyte colony stimulating factor (G-CSF). A case report].
abstract: A 69-year-old woman was admitted to the hospital complaining of general fatigue and lower abdominal pain. She had undergone total cystectomy because of invasive recurrent bladder carcinoma three months ago. Histopathological diagnosis was transitional cell carcinoma (TCC) grade 3 and squamous cell carcinoma (SCC), pT3a. A goose egg-sized painful mass was noticed at the lower abdominal region. A CT scan revealed an intrapelvic fist-sized mass and suggested tumor recurrence with ileus caused by intestinal invasion. The laboratory examination showed remarkable leukocytosis of 79,700/mm3 in the peripheral blood and serum analysis revealed high value of granulocyte colony stimulating factor (G-CSF), 240 pg/ml (normal: less than 30 pg/ml). In spite of active treatment, the patient died of cachexia about a month after detection of the leukocytosis. The autopsy showed that the recurrent tumor had positive immunohistochemical staining for G-CSF, and the bone marrow had reactive proliferation mainly by granulocytes. From these findings, this case was diagnosed as bladder carcinoma producting G-CSF. G-CSF producting tumor of the bladder is very rare. This was the 8th case in Japanese literatures. The previous reports were reviewed and discussed.
