Smooth Muscle Neoplasms of the Urinary Bladder

Smooth muscle neoplasms of the urinary bladder are relatively rare.


- leiomyomas
- leiomyosarcoma

Leiomyoma (including symplastic leiomyoma ) may be diagnosed on transurethral resection without risk of underdiagnosing unsampled leiomyosarcoma.

High-grade leiomyosarcomas are highly aggressive neoplasms compared with low-grade leiomyosarcomas; in most cases grade can be accurately determined on transurethral resection.
