A case of successful treatment of a female patient with ALK-positive inflammatory myofibroblastic tumor of the greater omentum

Inflammatory myofibroblastic tumors are a group of rare mesenchymal tumors which were considered by some authors to be benign; however, with accumulation of experience in treatment of these tumors their capability for invasive growth and metastasis was identified. The literature review showed a small number of clinical cases with intraabdominal forms of inflammatory myofibroblastic tumors. Mostly these are patients with tumors of the liver, upper gastrointestinal tract, pancreatobiliary area, small and large intestines. It should be noted that the literature review didn’t present any cases of isolated tumors of the greater omentum, hence we’ve decided to present a detailed description of a clinical observation of a female patient with rare ALK-positive inflammatory myofibroblastic tumor of the greater omentum.
