Osteosarcoma of Urinary Bladder- A Rare But Distinct Clinicopathological Entity: A Case Report

Bhavna P Sadhvani, Vijaya Kishore Tourani , and Vyas Naryana Rao

Primary osteogenic sarcoma of the urinary bladder is a rare tumor. We report a case of bladder mass in a 70 yr old male patient with histological features of osteogenic sarcoma. There was no prior history of malignancy elsewhere in the body. After the histopathological examination of the bladder mass, a thorough investigation including PET-CT did not reveal lesions elsewhere in the body. The histological features were similar to conventional osteogenic sarcoma. Immune marker studies were done to rule out other spindle cell sarcomas and carcinosarcoma.
