Inflammatory myofibroblastic tumors are uncommon and benign tumors with unknown aetiology. First reported in the lungs, the inflammatory myofibroblastic tumors have been observed in other locations, especially in the abdomen and the pelvis. We report a 14-year-old adolescent female, who presented sequentially an inflammatory pseudotumor of lymph node, the left kidney and the retroperitoneum. Extrapulmonary inflammatory myofibroblastic tumors are mesenchymal solid tumors. They are frequently circumscribed and confined to a single organ. The recurrence of some inflammatory myofibroblastic tumors and their expression of chromosomal abnormalities found in some types of lymphoma suggest that some of these lesions constitute a true neoplastic process.
