| Abstract: | Inflammatory myofibroblastic tumors (IMTs) rarely occur in the urinary bladder. It is apparently difficult to distinguish these tumors from other malignant spindle cell proliferations. Herein, we report a case of IMT of the urinary bladder with enlarged pelvic lymph nodes. The definitive pathological diagnosis could not be established by biopsy. Instead, the diagnosis of IMT of the urinary bladder was determined by a positive reaction to anaplastic lymphoma kinase by immunohistochemistry after radical cystectomy. No malignant findings were observed on histopathological evaluations of the enlarged lymph nodes.Key words: Inflammatory myofibroblastic tumor, Urinary bladder, Lymph node swelling |
