RATIONALE Inflammatory myofibroblastic tumor (IMT) is an uncommon neoplastic entity with a tendency of local recurrence and a low risk of distant metastasis. Involvement of trachea is extremely rare. PATIENT CONCERNS A 34-week pregnant woman previously diagnosed with asthma for 2 months was admitted with persistent wheezing and hemoptysis. A computed tomography scan and bronchoscopy revealed ...

Myofibroblastic dedifferentiation of well-differentiated liposarcoma (WDL) has rarely been documented, and WDL-associated low-grade osteosarcoma (OS) is extremely rare. Here we present a case of a 51-year-old man with three adjacent retroperitoneal masses corresponding to WDL, inflammatory myofibroblastic tumor (IMT)-like, and lowand high-grade OS components. Regarding the IMT-like and low-grad...

Benign intestinal tumors are rare in children; however, the authors describe an inflammatory myofibroblastic tumor (IMT) of the terminal ileum in a 2-month-old infant who presented with an intestinal obstruction. During laparotomy, an annular mass around the terminal ileum was resected, from which a histological diagnosis of IMT was made. A review of the literature for this rare condition was d...

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 ...

An inflammatory myofibroblastic tumor (IMT) is an uncommon, benign lesion characterized by the mesenchymal proliferation and infiltration of inflammatory cells composed primarily of lymphocytes and plasma cells. A percutaneous radiofrequency ablation (RFA) is an effective and safe therapeutic modality used for the management of liver malignancies. Here we report, for the first time, a case of I...

Inflammatory myofibroblastic tumor (IMT) or (plasma cell granuloma) of the larynx is a rare benign lesion that usually involves the lungs and broncopulmonary tree, as well as abdominal viscera. Overall this kind of tumor represents less than 1% of all tumors in the lung and respiratory tract with only 31 cases reported to date in the English language literature of laryngeal IMT. We report the f...

Inflammatory myofibroblastic tumor (IMT) belongs to the group of soft tissue tumor and could occur at any anatomical site from the central nervous system to gastrointestinal tract. The lung and abdomen are commonly affected sites, however, pulmonary IMT is predominantly located within the parenchyma rather than presenting as endobronchial lesion. IMTs may occur in any age group, but they are ob...

UNLABELLED Inflammatory myofibroblastic tumor (IMT) of the pancreas is an uncommon tumor with occasional recurrences and rare malignant transformation. We experienced a case of IMT in the body of the pancreas. The patient had no particular symptoms. Dynamic computed tomography revealed a 19-mm lesion in the body of the pancreas. RESULTS The patient underwent distal pancreatectomy, and has rem...

Abstract Inflammatory myofibroblastic tumors (IMTs) in the head and neck region are common, but those with sympathetic trunk involvement extremely rare. Here we present a case of cervical trunk-centered IMT which is also accompanied by ipsilateral carotid artery, internal jugular vein, vagus nerve involvement. The patient initially complained an episodic painful swelling on right side underwent...
