Here, the authors present two cases; one is the nine months old boy with a subcutaneous IMT in the left temporal region that was treated successfully with surgical resection A myofibroblastoma is a tumor composed mostly of a ' hybrid ' between fibroblasts and smooth muscle cells, while a solitary fibrous tumor is composed mostly of the fibroblastic cells. An inflammatory myofibroblastic tumor, sometimes also referred to as an ' inflammatory pseudotumor tumor ' ( IPT ), inflammatory myofibrocytic proliferation, or. Inflammatory myofibroblastic tumor (IMT) is a neoplasm of unknown etiology occurring at various sites. By definition, it is composed of spindle cells (myofibroblasts) with variable inflammatory component, hence the name is IMT. The present case is of a 46 years old woman presented with a history of flank pain, abdominal mass and intermittent hematuria for last 6 months Inflammatory myofibroblastic tumors (IMTs) are composed of myofibroblastic cells accompanied by an inflammatory infiltrate of plasma cells, lymphocytes and eosinophils.

Inflammatory myofibroblastic tumor in the chest is a rare finding, and making the histopathologic diagnosis is difficult when obtaining only a small biopsy tissue sample for frozen section. Inflammatory myofibroblastic tumor in the chest can be roughly classified into two groups according to location: tumors that develop in the lung parenchyma. Inflammatory myofibroblastic tumor (IMT) is a newly described entity, previously described as inflammatory pseudotumor. It most commonly involves the lungs and has been described in various body sites. On occasion, it can affect the larynx. A wide spectrum of histology has been reported under different terms in various case reports The most proper definition, formalized in the 1994 World Health Organization classification of soft-tissue tumors, is inflammatory myofibroblastic tumor, which refers to a tumor composed of differentiated myofibroblastic spindle cells usually accompanied by numerous plasma cells and/or lymphocytes

The etiology and pathogenesis remain elusive but 50% of the cases involve ALK locus on the 2p23 gene Inflammatory myofibroblastic tumor (IMT) is a rare benign neoplasm that frequently involves the lung and abdominopelvic region, and is mainly found in children and young adults [].The histological features of IMT include proliferation of spindle cells with a prominent inflammatory infiltrate consisting of plasma cells and lymphocytes, with occasional eosinophils and neutrophils [] Inflammatory myofibroblastic tumors (IMTs) of the thyroid are extremely rare soft-tissue tumors. In the literature, IMTs are sometimes called plasma cell granulomas (PCGs) or inflammatory pseudotumors, which often causes ambiguity. To date, 17 cases of PCGs and five cases of thyroid IMTs have been reported Inflammatory myofibroblastic tumors (IMTs) of the lung were first reported in 1939. The most common site of predilection is the lungs of the pediatric population. They are extremely rare in adults, constituting less than 1% of adult lung tumors.

  1. Rationale: Inflammatory myofibroblastic tumors (IMTs) are rare neoplastic lesions with benign tendency. Even more rare are IMTs from the greater omentum (GO-IMT). A GO-IMT is easily misdiagnosed as other malignant tumors before operation; thus, clinicians need to be familiar with its imaging findings. Here, we report the imaging findings of a GO-IMT patient presenting with a pelvic mass
  2. Purpose The aim of this study was to evaluate retrospectively 18 F-FDG PET/ CT findings of inflammatory myofibroblastic tumor (IMT) and their correlation with the pathologic findings.. Patients and Methods FDG PET/ CT findings were reviewed in 5 patients with IMT and 1 patient with spindle cell sarcoma transformed from IMT. PET/ CT scans were performed in all 6 patients before surgery
  3. Inflammatory myofibroblastic tumor (IMT) is an uncommon myofibroblastic neoplasm that was formerly included within the broad category of inflammatory pseudotumor (IPT). IMT is rarely encountered in the liver. Similar to IMT of other organs, the interchangeable use of the terms IMT and IPT in liver has made the analysis of these lesions difficult
  4. Inflammatory myofibroblastic tumor is a very rare benign tumor in children that mimics malignant tumors in its aggressiveness locally and by the possibility of recurrence after surgical resection, and causing anemia of chronic disease, which is a decrease in hemoglobin 1 to 2 g/dL below normal level in a patient with chronic illness. A 32-month-old boy from Libya presented with microcytic.
  5. Inflammatory myofibroblastic tumor has been reported with some frequency in both sexes across a wide spectrum of ages (7 days to 88 years). 1,2 A recent review article showed that most IMTs arising in the genitourinary tract occur in the fourth to fifth decades of life, with a male predilection (1.33:1 ratio). 1 In the genitourinary tract, IMT.
  6. Inflammatory myofibroblastic tumor (IMT) is a rare type of tumor presenting mostly in children and patients under 40 years of age . It is a neoplasm associated with the anaplastic lymphoma kinase (ALK) gene and classified as a subset of the inflammatory myofibroblastic pseudotumors
  7. Inflammatory myofibroblastic tumor (IMT) is a rare disease that usually occurs in the lung. IMT has been described by various terms because of its variable cellular components, which includes plasma cell granuloma, inflammatory pseudotumor, xanthogranuloma, and fibrous histiocytoma

Inflammatory myofibroblastic tumours are characterized by a mix of inflammatory cells, e.g. plasma cells, lymphocytes and eosinophils, and bland spindle cells without nuclear atypia. These tumours may have necrosis, hemorrhage, focal calcification and mitotic activity. The histologic differential diagnosis includes: calcifying fibrous pseudotumou Inflammatory myofibroblastic tumor (IMT) occurs mostly in children and young adults [] and usually involves the lungs and gastrointestinal tract; it rarely involves the heart.Since the first report of the cardiac involvement of IMT in 1975 [], there have been only a few additional reports, and sudden unexpected death due to cardiac IMT has rarely been reported in the medical literature [3, 4] Inflammatory myofibroblastic tumor (IMT) is a special type of mesenchymal tumors.

Pediatric Fibroblastic and Myofibroblastic Tumors: A

Introduction: Inflammatory myofibroblastic tumor (IMT) is a relatively new histopathologic term for an entity previously known as inflammatory pseudotumor, which is a rare pseudosarcomatous inflammatory lesion that occurs in the soft tissues of young adults. Objectives: The purpose of this review is to describe the pathogenesis, natural history. Inflammatory myofibroblastic tumor of the uterus (uIMT) is rare. However, it has been increasingly recognized in recent years, largely due to more awareness of its occurrence in the gynecologic tract and the characterization of features that help distinguish it from more common lesions in the differential diagnosis, particularly smooth muscle neoplasms Inflammatory myofibroblastic tumor of the larynx. A clinicopathologic study of eight cases simulating a malignant spindle cell neoplasm. Extrapulmonary inflammatory myofibroblastic tumor (inflammatory pseudotumor). A clinicopathologic and immunohistochemical study of 84 cases Inflammatory pseudotumor and inflammatory myofibroblastic tumor. Inflammatory pseudotumor (IPT) has become a misleading term, and it has been suggested that it should be avoided [].This expression is only descriptive and encompasses different entities, as inflammatory and infectious lesions (e. g., mycobacterial pseudotumor), and clonal processes, subsequently recognized as inflammatory.
