Abstract

Inflammatory myofibroblastic tumor of the urinary bladder is a rare mesenchymal tumor with uncertain malignant potential. It often mimics soft tissue sarcomas both clinically and radiologically. Surgical resection in the form of partial cystectomy or transurethral resection remains the mainstay of treatment. Herein we report the case of an inflammatory myofibroblastic tumor in a young girl, which was managed by laparoscopic partial cystectomy. To the best of our knowledge, this is the first reported case of laparoscopic management of an inflammatory myofibroblastic tumor of the urinary bladder.

  FIG. 1 Coronal (A) and cross-sectional (B) view of the contrast-enhanced computerized tomographic scan of the pelvis showing the bladder mass. (C) Laparoscopic view of the urinary bladder with the tumor mass (T). The tumor outline was defined by cystoscopic-guided transillumination. (D) Laparoscopic view of the urinary bladder (U) after resection of the tumor mass (T). The tip of the Foley catheter (F) can be seen inside the bladder.

  FIG. 2 (A) Tumor composed of oval to spindle-shaped cells having a high nucleocytoplasmic ratio, prominent nucleoli, and a moderate amount of eosinophilic cytoplasm along with unremarkable urothelial lining epithelium and increased mitotic figures (H&E, ×400). (B) Anaplastic lymphoma kinase immunohistochemistry revealed strong cytoplasmic staining of the myofibroblasts (×400).
