Abstract

Objective: Inflammatory myofibroblastic tumor (IMT) is a rare tumor. The etiology and biological behaviour is controversial. It could be seen in many different anatomical sites, however it is commonly seen in the lungs, mesentery, genitourinary tract and retroperitoneum. Uterine round ligament is a very rare location for IMT.
Case: We report the morphological, immunohistochemical and clinical features of an IMT which is located in the retroperitoneum / uterine round ligament of a young woman in this paper.
Conclusion: It is essential to differentiate IMT from benign and malignant mimickers for providing an appropriate therapy and follow-up.

Key words: Inflammatory, myofibroblastic, retroperitoneal
