Inflammatory myofibroblastic tumor: an enigma

Abstract

Abstract Background Inflammatory myofibroblastic tumor (IMT) of urinary bladder is a rare entity of genitourinary tract which has baffled urologists worldwide. Sign and symptoms are site specific. Usually diagnosed on the basis of immunohistochemistry findings. Case presentation 35-year-old female patient presented with gross hematuria since 10 days. Ultrasound revealed a hyperechoic mass from right lateral wall of urinary bladder. Patient was managed with complete transurethral resection of bladder tumor. Histopathology and immunohistochemistry was diagnostic for inflammatory myofibroblastic tumor. 2 months post-surgery patient developed recurrence, following which she was managed with partial cystectomy. Conclusion Inflammatory myofibroblastic tumor diagnosis is very challenging because of rarity of the tumor with non-specific presentation, and confirmation is done only by immunohistochemistry. Patients are usually managed with complete resection of tumor with regular follow-up.
