A 70-year-old man was found to have a submucosal mass near the scar of TUR-Bt by cystoscopy. MRI showed a round submucosal mass in the posterior wall with heterogeneous high intensity on T2-weighted image. Histologically, there were spindle cells with negative for ALK, positive for c-kit and DOG1, and the findings suggested gastrointestinal stromal tumor(GIST). Whereas, history of TUR-Bt, location and histological low cellularity strongly suggested postoperative spindle cell nodule(PSCN).
