Abstract
Inflammatory myofibroblastic tumor is a particular mesenchymal neoplasm caused by a proliferation of fibroblastic spindle cells in a myxoid stroma with an inflammatory background. Typically, the lesion occurs in young patients with a female predominance. It may affect a wide range of anatomic sites, but the majority of cases are described in lung and intra-abdominal soft tissue. The case described in this report regards a 28-year-old woman with a polypoid urinary bladder mass, without any anamnestic pathological history.
