Inflammatory myofibroblastic tumors following the treatment of malignancy in childhood: case reports.

Inflammatory myofibroblastic tumors (IMT) are rare, mostly benign soft tissue tumors. Occurring mainly in children the presentation, clinical features, and diagnostic dilemmas raised are well reported. Here we describe 4 patients diagnosed with IMT after the treatment of childhood cancer, and review the literature regarding IMT and malignancy. Discussing them in this context raises clinical questions; Are these tumors incidental or a consequence of treatment? Are they more common than we think and are any miss-diagnosed as tumor recurrence? This paper aims to raise awareness of IMT as diagnostic possibilities after treatment for childhood malignancies.
