Bladder preserving approach for treatment of primary osteogenic sarcoma of bladder: A rare case report.

Abstract

Abstract: Here, we present a rare case of a 74-year-old woman with intermittent haematuria for 6 months. Computed tomography urography showed an ill-defined heterogeneously enhancing soft tissue lesion near the neck of the bladder. The patient was advised of radical cystectomy with an ileal conduit for which the patient was unwilling. Hence, transurethral resection of bladder tumor was performed. Histopathological evaluation of surgical specimen revealed it to be primary osteosarcoma of the urinary bladder. The patient was given radiotherapy. Regular follow-up revealed no abnormality, and the patient showed excellent response with normal urinary tract function. Primary urinary bladder sarcomas are extremely rare clinical entities. To date, in scientific literature, fewer than 50 primary bladder osteosarcomas have been reported.
