Abstract
Inflammatory pseudo tumor (IPT) also known as inflammatory myofibroblastic tumor (IMT) is a tumor like mass of inflammatory origin. It is a pseudo sarcomatous lesion that has been reported most commonly in liver, followed by lung, mesentery and omentum but very rarely seen in esophagus. Proliferation of myofibroblastic cells is more in IMT. In IPT it is more of an inflammatory reactive or regenerative entity and has an overlapping with immunoglobulin G4-related disease. Lesion often mimics malignancy. A 20 year old male patient with history of dysphagia, more for liquids, underwent CT thorax, showing dilated oesophagus, with a moderately contrast enhancing eccentric soft tissue density lesion involving mid and lower esophagus extending for a length of 6cm. Patient underwent right thoracotomy, and a 5x3x3cm hard lesion involving lower esophagus was excised. Histopathology pointed towards inflammatory myofibroblastic tumor or inflammatory pseudotumor. Proliferation of myofibroblastic cells is more in IMT. In IPT it is more of an inflammatory reactive or regenerative entity and has an overlapping with immunoglobulin G4-related disease. Lesion often mimics malignancy.
