Inflammatory myofibroblastic tumor of the urinary bladder: A prognostically favorable spindle cell neoplasm

ABSTRACT

@#Inflammatory myofibroblastic tumors (IMT) are rare, benign spindle cell neoplasms of the urinary bladder with a presentation similar to that of a malignant disease. Oftentimes, these tumors pose a diagnostic dilemma because of a significant overlap with malignant spindle cell tumors in terms of clinical presentation, gross findings and immunohistopathologic profile. Due to its rarity, there are no guidelines regarding treatment and follow up. Reporting cases of IMT will bring awareness to the features of these rare tumors, and will help in overcoming limitations in diagnosis, and treatment protocols. Presented here is a case of a 28-year-old female who presented with gross hematuria. Upon work up, revealed the presence of a bladder mass. Patient underwent transurethral resection, then a partial cystectomy, and pathology demonstrated an IMT.
