Multivisceral resection for synchronous inflammatory myofibroblastic tumors of the lung and stomach

Inflammatory myofibroblastic tumor is a mesenchymal tumor which commonly originates from lungs. In this paper we report the successful resection of multiple inflammatory myofibroblastic tumors invading thoracic, mediastinal and abdominal viscera in a 14-year old child. We could achieve an RO resection with distal esophagectomy, proximal gastrectomy, splenectomy, left hepatectomy, left pneumonectomy, left diaphragm resection and pericardiectomy. To our knowledge, this is the first case reporting synchronous gastric and pulmonary inflammatory myofibroblastic tumors. The patient is alive without disease after 33 months.
