Carcinosarcoma of the bladder: case report and review of the literature
DOI:
https://doi.org/10.5489/cuaj.678Abstract
Primary osteosarcomas of the bladder account for about 0.04% ofbladder neoplasms. Most of the patients in the literature expired
within 6 months and, in almost all of the cases in the literature,
radical cystectomy with postoperative chemotherapy was the
treatment choice. A 79-year-old gentleman presented with gross
hematuria. Cystoscopy demonstrated a 2- to 3-cm tumour along the
lateral wall of the bladder. The tumour was resected incompletely
via initial transurethral resection of bladder tumour (TURBT), and
a second TURBT was subsequently performed to fully resect the
residual mass. Surgical pathology from these 2 resections revealed
osteosarcoma with invasion into the muscularis propria. A
cystoprostatectomy was performed and final pathologic specimen
revealed high-grade CIS without evidence of residual osteosarcoma.
Postoperatively, the patient did not receive chemotherapy or
radiation and currently remains disease-free 2 years post-radical
cystectomy. Only 33 well-documented cases of primary osteosarcoma
of the bladder have been reported to date. However, there
are only 3 cases in which TURBT resulted in complete resection.
