vesical smooth muscle tumors
Tuesday 23 February 2010
Smooth muscle neoplasms of the urinary bladder are relatively rare.
Types
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.
