ABSTRACT = {Osteosarcoma is a highly malignant soft tissue tumor. 
Bladder extra-skeletal osteosarcomas are very rare, and only 
few cases are reported in the English medical literature. This 
case is the third one of its kind to be reported consisting of a 
bladder diverticulum osteosarcoma. Compared to urothelial 
bladder carcinoma, urinary bladder osteosarcomas have a 
poorer prognosis. Biopsy and immunochemical staining 
are critical for the diagnosis. Treatment regimens vary 
based on the stage of the disease. However, choosing the 
best option for treatment is still unclear, due to the scarcity 
of cases available.},
