Inflammatory Myofibroblastic Tumor of the Bladder in an Adolescent Girl: A Case Report on Successful Management With Partial Cystectomy.

Inflammatory myofibroblastic tumors (IMTs) are rare bladder tumors that are difficult to differentiate from other malignant bladder tumors because of their non-specific presentation. Histopathology and immunohistochemistry serve as the main diagnostic tools in such cases. They have a very low malignant potential but can frequently recur. However, there are limited guidelines with regard to the choice of treatment for these tumors. This case scenario pertains to a 16-year-old female patient who had gross hematuria and fever, devoid of additional symptoms. Further evaluations uncovered a neoplastic mass lesion emerging from the left dome of the urinary bladder. Following transurethral resection of the bladder tumor, histopathological examination was consistent with an IMT. The patient underwent a partial cystectomy, and the diagnosis was established by histopathology and immunohistochemistry. Vigilant monitoring, post-surgery showed no signs of recurrence or metastasis during the six-month and one-year follow-up. This case underscores the significance of a precise diagnosis of the rare bladder tumor and emphasizes the need for tailored treatment to ensure comprehensive care and prevent recurrence.
