title: Recurrent retroperitoneal inflammatory myofibroblastic tumor: A case report.
abstract: Inflammatory myofibroblastic tumor (IMT), which was previously known as inflammatory pseudotumor, is characterized by myofibroblastic spindle cells accompanied by inflammatory infiltrates. IMT is a rare lesion of unclear etiology, which induces non-specific clinical symptoms. The present case report describes a 74-year-old female patient with recurrent IMT, which was successfully re-resected 30 months subsequent to initial surgical removal. The patient presented with left hydroureteronephrosis and a 10-cm paravertebral mass which, upon surgery, was found to involve the descending colon. Successful, complete en bloc re-resection was achieved, and at 24 months follow-up, the patient remained clinically free of disease. Complete surgical extirpation, where feasible, is the recommended treatment for primary and recurrent IMT lesions.
