Immunohistochemistry of Inflammatory myofibroblastic tumors

Abstract

Background: Inflammatory myofibroblastic tumor (IMT) or inflammatory pseudotumor is a tumoral lesion which can be seen in all age groups and in all internal organs. It is in differential diagnosis with some important neoplasms such as Leiomyosarcoma, Rhabdomyosarcoma, and Sarcomatoid carcinoma. Differentiation between these tumors requires a special diagnostic tool such as Immunohistochemistry (IHC). This study aimed to identify Immunohistochemical characteristics of inflammatory myofibroblastic tumors.
