title: Dysuria and fever in a young woman diagnosed as having inflammatory myofibroblastic tumour of the urinary bladder.
abstract: A 38-year-old woman presented with dysuria and fever. Her medical and family histories were unremarkable. CT scan of the abdomen revealed a polypoid mass of 4×2.6×2.2 cm. Her cystoscopy showed a 4×2 cm solid broad-based growth at trigone of the urinary bladder. She underwent transurethral resection of the urinary bladder tumour (TURBT). Histopathology revealed a poorly circumscribed proliferation of spindle cells arranged in a haphazard and fascicular manner along with many traversing blood vessels in a myxoid and hyalinised stroma. Immunohistochemistry was positive for anaplastic lymphoma kinase-1, smooth muscle actin, CD10, cytokeratin and desmin; and negative for CD34 and S-100 protein. Ki-67 proliferative index in the tumour was <1%. The patient was diagnosed as having inflammatory myofibroblastic tumour of the urinary bladder. After TURBT, her fever and urinary symptoms resolved. Her 1-month postoperative period was uneventful. She has been advised regular follow-up.
