Abstract
A gastrointestinal stromal tumor is the most common mesenchymal tumor of the gastrointestinal tract, and is diagnosed on the basis of the combined expression of CD34 and CD117 (C-kit protein). An extragastrointestinal stromal tumor of the urinary bladder is a very rare neoplasm. In this report, we describe a case of an extragastrointestinal stromal tumor originating from the inner surface of the urinary bladder. A 46-year-old man presented with an incident bladder mass, and he was diagnosed with an extragastrointestinal stromal tumor after transurethral resection of the bladder tumor. A tumor on the inner urinary bladder wall is an unusual presentation of an extragastrointestinal stromal tumor. The patient is doing well with no recurrence at 18 months after surgery.
