title: [DISSEMINATED CARCINOMATOSIS OF THE BONE MARROW WITH UROTHELIAL CARCINOMA].
abstract: Disseminated carcinomatosis of the bone marrow with urothelial carcinoma in a 75-year-old man: A case study. A 75-year-old-man had first medical examination due to gross hematuria. The imaging study and cystoscopy revealed left ureteral and bladder tumor. The patient was referred for a laparoscopic assisted left nephroureterectomy and transurethral resection of a bladder tumor (TUR-Bt). Pathological findings included urothelial carcinoma, high grade, both a pT3 ureteral tumor and a pTa bladder tumor. The patient received 2 courses of gemcitabine and cisplatin and 1 course of methotrexate, epirubicin and nedaplatin as adjuvant chemotherapy. TUR-Bt was performed twice due to recurrence in the bladder and similar pathological findings. The patient received intravesical instillation of pirarubicin (THP 30 mg in 30 mL of saline) to prevent recurrence in the bladder, but discontinued in the 3rd time because of gross hematuria. The patient was then admitted to our hospital due to gross hematuria, general fatigue, and abnormal findings in the blood analysis. On admission, pancytopenia was detected and the serum ALP level had increased to 30,266 IU/L. A biopsy and bone marrow aspiration were performed because a super bone scan image was obtained using a bone scintigram. Diffuse bone marrow metastasis of the urothelial carcinoma was observed in the pathological evaluations. Therefore, our diagnosis was urothelial carcinoma with disseminated carcinomatosis of the bone marrow. Although treatment with zoledronic acid and blood transfusion were performed, the patient died 20 days after the admission. To the best of our knowledge, this is the first case of disseminated carcinomatosis of the bone marrow with urothelial carcinoma.
