Inflammatory myofibroblastic tumor: a rare clinical case of bladder pathology

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm characterized by proliferation of spindle‑shaped cells with prominent inflammatory cell infiltration. IMT is also referred to as an inflammatory pseudotumor or pseudosarcomatous myofibroblastic tumor. Although it accounts for less than 1% of all bladder tumors, the bladder is the most frequent site of IMT within the genitourinary tract. In this report, we present the case of patient M., a 1‑year‑7‑month‑old child with a 2‑month history of dysuria and painful voiding. Following a diagnostic work‑up, including ultrasound, voiding cystography, abdominal and pelvic CT, cystourethroscopy, and pelvic MRI, the child underwent surgical excision (enucleation) of the mass with negative margins. Histopathological examination confirmed the diagnosis of IMT. During 2 years of follow‑up with ultrasound, CT, and MRI, no evidence of local recurrence was detected, which is consistent with published data indicating low recurrence rates after organ‑sparing surgical management without adjuvant chemotherapy.
