Abstract
Primary retroperitoneal inflammatory myofibroblastic tumors (IMT) are a very rare clinical condition. Herein, we present a case of IMT in the retroperitoneal area. A 52-year-old woman presented with abdominal lump and exhaustion. On physical examination, there was no pathological finding. The diagnostic workup included contrast computer tomography that revealed a 10,5-cm heterogeneous retroperitoneal mass under the right adrenal gland, localized behind the right kidney. At laparotomy, the mass arising from the retroperitoneum was excised. Histopathology showed an IMT. IMTs has a variable biologic behavior that ranges from the frequently benign lesions to more aggressive variants. Final diagnosis is based on histomorphological features. Complete surgical excision should be the aim of the curative treatment.
