[A case report of sarcomatoid carcinoma of the bladder with metastasis to small intestine].
A 67-year-old male presented to our clinic with gross hematuria. Cystoscopic examination revealed a broad-based tumor of 2.5 cm in diameter on the lateral side of the right ureteral orifice. Under the clinical diagnosis of TCC G2 > G3, T3bNOM0, radical cystectomy with orthotopic bladder substitution was performed. Pathological diagnosis was TCC G3 with sarcomatoid carcinoma, pT2pR0pL1 pVlpN0. Adjuvant chemotherapy was not performed because of his transient poor conditions. Lung metastasis was observed 6 months postoperatively. Despite of M-VAC therapy and radiation therapy, additional metastases to brain and liver were observed. One month later, partial ileectomy specimen for occlusive ileum revealed the same histologic findings, TCC G3 with sarcomatoid carcinoma. He died 9 months postoperatively. To our knowledge, this is the first case of sarcomatoid carcinoma of the bladder with metastasis to small intestine, although 6 cases of transitional cell carcinoma of the bladder with metastasis to small intestine has been reported in Japan.
