RESUMEN
This article reported a case of Inflammatory myofibroblastic tumor of the bladder combined with cystitis glandularis. The patient was admitted to the hospital after hematuria for more than 20 days and occasionally accompanied with dysuria.Preoperative imaging examination showed a space-occupying lesion on the anterior bladder wall, with a size about 7.7 cm×6.1 cm×4.4 cm, considering the possibility of bladder cancer. Laparoscopic robot-assisted partial cystectomy was performed, and the postoperative pathological diagnosis was cystitis myofibroblastic tumor combined with cystitis glandularis. Cystitis myofibroblastic tumor is a true tumor originating from the bladder parenchyma, which is a rare clinical disease, and it combined with cystitis glandularis has not been reported. Because its clinical manifestations and imaging manifestations are difficult to distinguish from bladder malignant tumors, the diagnosis mainly depends on pathology and immunohistochemistry stain.
