A Case of an Inflammatory Myofibroblastic Tumor Mimicking Appendicitis.

Inflammatory myofibroblastic tumors (IMTs) are rare tumors that have been described only in a few cases in the literature. IMTs are mesenchymal neoplasms that typically affect children and young adults. The most common anatomical locations are the abdominopelvic region, lung, and retroperitoneum, but any site may be involved. Given that there are no clinical or radiographic characteristics specific to IMTs, the diagnosis is made by pathology. We report on a young woman presenting with an acute appendicitis-like clinical picture due to an IMT located in the ascending colon to raise awareness of this rare, but possible presentation.
