A rare case of inflammatory myofibroblastic tumour of the thigh : A case report and literature review

Towards the beginning of the twentieth century, inflammatory myofibroblastic tumors were described as neoplasms characterized by myofibroblastic spindle cells with an infiltrate of inflammatory cells. These rare tumors occur mainly in children and young adults with a preferential pulmonary and abdominal location. They have intermediate biological potency with a tendency to local recurrence and rarely metastasize. We describe the case of an adolescent who presented with an inflammatory myofibroblastic tumor of the thigh, a very rare entity that has only been reported in the literature as case reports, and its clinical, radiological, echographic and MRI appearance. The patient underwent complete surgical resection of the mass with healthy margins and did not receive any additional treatment. No sign of recurrence was detected after 6 months of follow-up.
