“…The location of such a lesion in the genitourinary tract was then described by Roth [2] in 1980. IMT has been called plasma cell granuloma, inflammatory pseudotumor, pseudomalignant spindle cell proliferation, or pseudosarcomatous myofibroblastic tumor [3]. Confusion regarding nomenclature may have contributed to the difficulty of establishing standard therapeutic procedures for this disease [4].…”

Introduction: The inflammatory myofibroblastic tumor is a rare tumor. It most often occurs in the bladder in the genitourinary sphere. This benign and aggressive spindle cell tumor affects children and frequently girls. The objective of this work is to describe from a clinical case, the clinical, radiological, and histological characteristics of an inflammatory myofibroblastic tumor in an 8 years old girl. Case Presentation: An 8-year-old girl was followed for an inflammatory myofibroblastic tumor of the bladder revealed by micturition burns complicated by hematuria. She underwent an ultrasound and radiological workup demonstrating an anterior bladder parietal mass reaching the rectus abdomen is muscle. Subsequently, an excisional biopsy was performed and histological and immunohistochemical examination revealed an inflammatory myofibroblastic tumor. Discussion: Inflammatory myofibroblastic tumors of the bladder are benign tumors with aggressive features usually revealed by voiding symptoms, pelvic pain, and pelvic mass. Treatment is based on Trans urethral resection of the bladder. Anatomical pathology examination shows spindle-shaped myofibroblast and fibroblast cells, a collagenous or myxoid matrix, and inflammatory cells composed of plasma cells, lymphocytes, and eosinophils. The diagnosis is confirmed by immunohistochemistry with an expression of CAM5.2, desmin, aSMA, and vimentin and especially of Anaplasic Lymphoma Kinase (ALK). Conclusion: Rare tumor process, whose malignant potential remains unknown. Management is by conservative surgery of the bladder.
