Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) of the stomach is an uncommon mesenchymal neoplasm. We present a case of gastric submucosal tumor (SMT) where the final diagnosis was IMT. CASE PRESENTATION A 69-year-old man presented with a 24-mm SMT on the posterior wall of the middle third of the stomach that was detected by screening upper gastrointestinal endoscopy. Abdominal contrast-enhanced computed tomography showed that the tumor was well-enhanced. Although endoscopic ultrasonography-guided biopsy was performed, the histological diagnosis was not confirmed preoperatively. Since the tumor was clinically suspected to be a gastrointestinal stromal tumor, we performed gastric wedge resection by laparoscopic-endoscopic cooperative surgery. Pathologically, proliferative spindle cells with a positive reaction for smooth muscle actin, negativity for c-kit, desmin, s-100, CD34, STAT-6, β-catenin and anaplastic lymphoma kinase 1 were identified. Hence, the tumor was finally diagnosed as an IMT originating from the stomach. CONCLUSIONS When an SMT of the stomach is identified, the possibility of gastric IMT should be considered.

Abstract
The recognition of immunoglobulin G4-related disease (IgG4-RD) as an entity in the pancreaticobiliary tract was followed by a slew of papers describing inflammation and fibrosis containing IgG4-positive plasma cells in a variety of sites including the respiratory tract, leading to the hypothesis that these abnormalities were attributable to IgG4-RD. Predictably, pathologists began to see requests from clinicians to perform IgG4 immunohistochemistry in lung biopsies "to rule out IgG4-RD". Several years later, the notion that IgG4-RD would prove to be the underlying cause of a wide array of fibroinflammatory lesions in the lung has not panned out as promised. To the contrary, it has become clear that IgG4-positive plasma cells are not specific for IgG4-RD, and that large numbers of IgG4-positive plasma cells can be encountered in other well-defined entities, including inflammatory myofibroblastic tumor and nodular lymphoid hyperplasia, as well as in lymphoplasmacytic infiltrates in other entities, including connective tissue disease and idiopathic forms of interstitial lung disease. It has also become clear that raised serum IgG4 levels can occur in settings other than IgG4-RD. These observations suggest that true IgG4-RD of the lung is far less common than previously surmised. Pathologists must familiarize themselves with mimics of IgG4-RD in the lung and exercise caution before attributing lymphoplasmacytic infiltrates in the lung to IgG4-RD.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is an uncommon cardiac tumor that primarily affects infants, children, and young adults. While complete surgical resection generally leads to a favorable prognosis, accurate diagnostic tests remain limited. CASE PRESENTATION We describe the case of a 26-year-old female who had a dual tumor inside and outside the heart and was misdiagnosed by echocardiography and MRI. We also review 71 cases of cardiac IMTs from the literature regarding their epidemiology, clinical presentation, and outcome. CONCLUSION Early detection of this rare disorder is essential for optimal surgical management.

Abstract
BACKGROUND We present a case of an inflammatory myofibroblastic tumor cured with a short period of steroid administration, a treatment previously unreported for such cases. CASE PRESENTATION A 49-year-old man had a chief complaint of chest pain for more than 3 days. Computed tomography (CT) revealed a tumoral lesion suspected to have infiltrated into the right first rib and intercostal muscles, with changes in lung parenchymal density around the lesion. The maximal standardized uptake value on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography was high (16.73), consistent with tumor presence. CT-guided biopsy revealed an inflammatory myofibroblastic tumor with no distant metastases. Surgery was indicated based on the disease course. However, he had received an oral steroid before the preoperative contrast-enhanced CT scan due to a history of bronchial asthma, and subsequent CT showed that the tumor shrank in size after administration; he has been recurrence-free for more than a year. CONCLUSIONS Surgery is still the first choice for inflammatory myofibroblastic tumors, as the disease can metastasize and relapse; however, this condition can also be cured with a short period of steroid therapy.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a rare stromal tumor, often found in children and young adults, and most commonly occurs in the lungs. Surgical resection is considered the standard treatment for localized IMT, although only limited data exist. Gastric IMT in adults is extremely rare, and there are no established guidelines for its treatment. CASE PRESENTATION A 69-year-old male presented with persistent fatigue and weakness. Laboratory examination revealed severe anemia and inflammation. Upper gastrointestinal endoscopy at admission revealed a 40-mm type I softish tumor in the lesser curvature of the gastric body, without apparent hemorrhage. Repeated biopsies, including partial resection with snare, failed to give a definitive diagnosis. Computed tomography (CT) revealed a massive lesion at the gastric body, protruding into the gastric lumen, which was consistent with the gastric tumor. After admission, the patient developed anemia refractory to frequent blood transfusions despite the absence of apparent gastrointestinal bleeding. In addition, the patient had recurrent fevers of 38 °C or higher, and persistent high inflammatory levels. Fluorodeoxyglucose-positron emission tomography (FDG-PET) CT 1 month after the first visit exhibited an increased FDG uptake in the gastric tumor. In addition, this CT scan revealed a rapid increase in tumor size to 75 mm. It was suspected that the undiagnosed gastric tumor caused these serious clinical symptoms, and he underwent distal gastrectomy and cholecystectomy. The gross image of the tumor showed an 80-mm cauliflower-like shape with a gelatinous texture. The histopathological diagnosis was IMT. The postoperative course was uneventful, and the patient's symptoms subsided drastically, improving both anemia and systemic inflammation. The patient has shown no recurrence or relapse of the symptoms over one and a half years. CONCLUSIONS In this case, the tumor resection finally enabled the diagnosis of IMT and resolved the clinical symptoms. Despite its predominantly benign morphological nature, some cases of IMT present clinically adverse courses. Surgical treatment may lead to its final diagnosis and improvement of clinical symptoms.

Abstract
Inflammatory myofibroblastic tumors of the bladder (IMTB) are rare neoplasms that can occur in children. These tumors have uncertain malignant potential and can present similarly to bladder sarcomas. It is important to differentiate between IMTB and bladder sarcomas using a careful immunohistochemical approach. We report a case of IMTB in a 12-year-old girl who presented with presyncope and gross hematuria. IMTB was diagnosed through immunohistochemical analysis, and clinical improvement was observed after resection of the tumor.

Abstract
Inflammatory myofibroblastic tumors (IMTs) are rare lesions with distinct clinical, pathological, and molecular characteristics. IMTs typically arise in the abdominal soft tissues, including the mesentery, omentum, and retroperitoneum, followed by the lungs and mediastinum, and usually affect both children and young adults. Herein, we present a rare case of an IMT in the submandibular gland of a 47-year-old male patient. Microscopically, the tumor displayed an infiltrative growth pattern with diffuse glandular tissue destruction. Their backgrounds revealed characteristic spindles and inflammatory cells. Immunohistochemistry revealed positivity for anaplastic lymphoma kinase (ALK), smooth muscle actin, and calponin in neoplastic cells. The inflammatory cells and some neoplastic cells were positive for CD68. In contrast, negative staining for cytokeratin, desmin, and CD30 was observed. Furthermore, fluorescence in situ hybridization revealed ALK gene rearrangements, and next-generation sequencing detected a moesin (MSN)-ALK gene fusion. This case highlights a rare and unique occurrence of IMT originating from the submandibular gland, which exhibited an MSN-ALK gene fusion.

Abstract
OPINION STATEMENT: Inflammatory myofibroblastic tumor (IMT), characterized by intermediate malignancy and a propensity for recurrence, has presented a formidable clinical challenge in diagnosis and treatment. Its pathological characteristics may resemble other neoplasms or reactive lesions, and the treatment was limited, taking chemotherapies as the only option for those inoperable. However, discovering anaplastic lymphoma kinase (ALK) protein expression in approximately 50% of IMT cases has shed light on a new diagnostic approach and application of targeted therapies. With the previous success of combating ALK+ non-small-cell lung cancers with ALK tyrosine kinase inhibitors (TKIs), crizotinib, a first-generation ALK-TKI, was officially approved by the U.S. Food and Drug Administration in 2020, to treat unresectable ALK+ IMT. After the approval of crizotinib, other ALK-TKIs, such as ceritinib, alectinib, brigatinib, and lorlatinib, have proven their efficacy on ALK+ IMT with sporadic case reports. The sequential treatments of targeted therapies in may provide the insight into the choice of ALK-TKIs in different lines of treatment for unresectable ALK+ IMT.

Abstract
BACKGROUND The inflammatory myofibroblastic tumor (IMT) is a rare mesenquimal tumor of doubtful biological behaviour. It's characterised for affecting mainly children and young adults, although it can appear at any age, being the lungs the primary affected organ (in children it represents 20% of all primary pulmonary tumors). CASE SUMMARY We present the case of a 45 year old woman, with a computed tomography (CT) finding of injury on the anterior surface of the fundus/gastric body and a solid perigastric injury of 12 mm in the ecoendoscopy. The case is presented in the tumor committee deciding to perform a laparoscopic wedge resection. The histological diagnosis was a IMT. The diagnosis is based on imaging tests like the abdominal CT, abdominal ecography and the ecoendoscopy but to confirm the diagnosis a pathological study is necessary. CONCLUSION Due to the unpredictable nature of this tumor, surgical resection is the best therapeutic option.

Abstract
Inflammatory myofibroblastic tumors (IMT) are rare spindle cell neoplasms derived from mesenchymal cells. Primary genitourinary IMTs share morphological and molecular features with various malignant spindle cell sarcomas, which introduces a diagnostic challenge. We present the case of a 50-year-old female who was referred for evaluation of hematuria and nonspecific urinary symptoms and was found to have a mass originating from the urinary bladder that involved the cervix and right ovary. Transurethral resection of bladder tumor (TURBT) and immunohistochemical analysis revealed an IMT. To our knowledge, this is the first documented case of primary genitourinary IMT with cervical and ovarian involvement.

Abstract
Renal inflammatory myofibroblastic tumor (IMT) is an exceptionally uncommon occurrence. This report presented the first documented case of renal IMT coexisting with hemophilia A carrier status. A 52-year-old asymptomatic female was incidentally discovered to have a kidney mass during a routine computed tomography (CT) scan spanning a 5-month period. Ultrasonography and contrast-enhanced CT scan raised suspicion of a potential renal malignant tumor. Over 2 decades ago, the patient experienced significant bleeding during childbirth, and she possessed a 5-year history of rheumatoid arthritis. Following a radical surgical procedure, intravenous supplementation of factor VIII was administered during the perioperative period. Subsequent to strenuous defecation, the patient encountered hematuria. Continued coagulation factor supplementation led to alleviation of hematuria symptoms. The underlying causes and pathogenesis responsible for IMT remain unclear. IMT is often associated with rheumatoid arthritis, possibly suggesting a connection to its etiology. Surgical excision stands as the primary approach to treatment, with recurrence being an exceedingly rare event. In instances where hemophilia is a complicating factor, vigilant monitoring of coagulation function and appropriate coagulation factor supplementation is imperative.

Abstract
A 13-year-old male patient presented with right leg pain and walking difficulty. Contrast-enhanced magnetic resonance imaging showed a softtissue lesion between muscle groups in the anterior half of the right thigh. The excisional biopsy result ended in an inflammatory myofibroblastic tumor (IMT). The 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) scan showed hypermetabolism in the multifocal soft tissue lesion and also confirmed that no other distant foci were present. A three-phase Tc-99m-methylene diphosphonate study of the region showed heterogeneously increased vascularity within the region. We described an unusual case of IMT in a pediatric patient and the importance of PET/CT scanning to delineate the lesion.

Abstract
INTRODUCTION AND IMPORTANCE Inflammatory myofibroblastic tumor (IMT) is an infrequent, generally non-cancerous mesenchymal growth. IMT can affect individuals across various age groups, with a higher prevalence in children and adolescents. While it can emerge in any bodily region, it has a tendency to develop more often in the lungs and mesentery. IMT occurrence in the small bowel is exceptionally uncommon. It's a rare cause of intussusception and has unpredictable recurrence rate. CASE PRESENTATION This report highlights a unique clinical presentation involving a mesenteric IMT, which presented as small intestine intussusception in a 2-year-old child. Additionally, the patient was found to have an asymptomatic mass in the right upper quadrant, later identified as a recurrent IMT 10 months after surgical intervention for intussusception caused by the same tumor. CLINICAL DISCUSSION IMTs originate from mesenchymal tissues and encompass a blend of fibroinflammatory conditions. They exhibit a diverse combination of inflammatory and spindle cells. Diagnosing IMTs prior to surgery is intricate, as they can mimic malignant growths. Histopathology following surgery is usually needed for confirmation. Complete removal with a clear margin is the favored treatment approach. CONCLUSION Intestinal IMT is an infrequent and often overlooked condition, but it should be taken into account when diagnosing small bowel intussusception. The best chance of preventing recurrence in cases of intestinal IMT is through complete surgical removal with a negative margin. Nonetheless, the most effective approach for managing local recurrence and metastasis is still uncertain and necessitates ongoing long-term observation.

Abstract
We report two cases of Intracranial inflammatory myofibroblastic tumor (IMT) with recurrent, cystic, and venous sinus occlusion. The cases show imaging progression from a small lesion (case 1) or absence of lesions (case 2). One of cases recurred 2 years after surgery and was treated with corticosteroids but the tumor was still growing and was resected again. We think the best treatment for IMT is surgical resection.

Abstract
Hepatic inflammatory pseudotumor (IPT) describes a mass lesion composed of fibroblasts or myofibroblasts with a dense inflammatory infiltrate comprising lymphocyte, plasma cells, and histiocytes. These lesions are presumed to be an exuberant response to an infectious organism, although in most cases the causative agent is unknown. In specific circumstances, pathologists should consider ancillary techniques to exclude specific infections, such as mycobacteria, Candida, or syphilis. IgG4-related disease may cause a plasma-cell rich IPT. Finally, true neoplasms can mimic IPTs and must be excluded with appropriate ancillary studies, including inflammatory myofibroblastic tumor, follicular dendritic cell tumor, inflammatory angiomyolipoma, Hodgkin lymphoma, and inflammatory hepatocellular carcinoma.

Abstract
Inflammatory myofibroblastic tumor (IMT) of the biliary tract is rare, and often difficult to diagnose or to distinguish from other tumors due to its atypical clinical presentation and nonspecific radiological features. Histologically, IMTs are (myo)fibroblastic neoplasms with a prominent inflammatory infiltrate. They are characterized by receptor tyrosine kinase gene rearrangements, most often involving an anaplastic lymphoma kinase (ALK) translocation. The final diagnosis of IMT depends on histopathology and immunohistochemical examination. In this manuscript, we provide a clinical and morphomolecular overview of IMT and the difficulties that may arise in using immunohistochemical and molecular techniques in diagnosing IMT.

Abstract
INTRODUCTION AND IMPORTANCE An inflammatory myofibroblastic tumor (IMT) is an uncommon solid neoplasm of mesenchymal origin. They are usually seen in children and adolescents and commonly affect the lung, but they can nearly arise from every organ. The prevalence of IMT in the small bowel is very rare. The tumors have generally a benign clinical course, with some risk of local recurrence or distant metastasis. PRESENTATION OF CASE This is a 55-year-old male patient who presented with intermittent abdominal pain, vomiting of ingested matter and loss of appetite for 2 weeks duration. On physical examination, he had stable vital signs and the abdominal examination was non-revealing. Abdominal CT scan with contrast showed a long segment jejunojejunal intussusception. He underwent en-bloc resection of the mass and end-to-end anastomosis of the jejunum. CLINICAL DISCUSSION IMTs have a mesenchymal origin and are grouped into a mixture of fibroinflammatory disorders. They show a variable mix of inflammatory cells with spindle cells. The diagnosis of IMT preoperatively is challenging often mimicking malignant lesions. The diagnosis is often confirmed by histopathology after surgery. Complete excision with a negative margin is the preferred treatment. We report a rare case of jejunal IMT presenting with intussusception. CONCLUSION An intestinal IMT is a rare and an underdiagnosed entity, and should be considered in the differential diagnosis of small bowel intussusception. Surgery is still the most favored and effective treatment for intestinal IMT. Complete surgical excision with a negative margin has the least chance of disease recurrence.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a relatively rare tumor. The global incidence of IMT is less than 1%. There is no specific clinical manifestation. It usually occurs in the lungs, but the pancreas is not the predilection site.
CASE SUMMARY We present a case of a male patient, 51 years old, who was diagnosed with a pancreatic neck small mass on ultrasound one year ago during a physical examination. As he had no clinical symptoms and the mass was relatively small, he did not undergo treatment. However, the mass was found to be larger on review, and he was referred to our hospital. Since the primal clinical diagnosis was pancreatic neuroendocrine tumor, the patient underwent surgical treatment. However, the case was confirmed as pancreatic IMT by postoperative pathology.
CONCLUSION Pancreatic IMT is relatively rare and easily misdiagnosed. We can better under-stand and correctly diagnose this disease by this case report.

Abstract
INTRODUCTION AND IMPORTANCE Spindle cell tumors in the paratesticular region are infrequent. Accurate diagnosis requires clinical assessment, pathological analysis, and immunohistochemical (IHC) analysis. CASE PRESENTATION The present study reports a 33-year-old male who presented with a painless mass in his right testis. The mass grew from the size of a marble to that of a tennis ball in two years. Physical examination and ultrasonography revealed a solid mass in the right paratesticular area. The patient underwent a right paratesticular tumor excision, without interfering the right testis. Histopathologic analysis showed spindle cell tumor appearance referring to inflammatory myofibroblastic tumor (IMT). CLINICAL DISCUSSION IMT, also known as inflammatory pseudotumor, is a rare and benign neoplasm that can occur anywhere. Diagnosis is challenging, because it mimics other neoplasms. Immunohistochemical profiles were decisive in concluding a definitive diagnosis. Treatment, on the other hand, depends on tumor burden and connectivity to other region. CONCLUSION Spindle cell tumors are very rare and can be treated with simple excision if no organ adhesion is detected. Therefore, right orchidectomy was not required in our case.

Abstract
INTRODUCTION The inflammatory myofibroblastic tumor (IMT) is a very rare lesion with an incidence of less than 0.1% of total neoplasms and with main affection in the lungs. Involvement in the central nervous system is extremely rare, but with a much more aggressive course than IMT diagnosed in the rest of the body. We report the 2 cases presented in our neurosurgery department to date; both were treated satisfactorily without intercurrences in 10 years of follow-up. HISTORICAL BACKGROUND The World Health Organization described the IMT as a distinctive lesion composed of myofibroblastic spindle cells accompanied by an inflammatory infiltrate of plasma cells, lymphocytes, and eosinophils. CLINICAL PRESENTATION Clinical manifestations of patients with CNS IMT vary and may consist of headache, vomiting, seizures, and blindness. Seizures are the most common symptom in patients with focal lesions. DIAGNOSIS The true origin of this entity remains to be elucidated, but to date, etiologies ranging from chromosomal alterations to autoimmune or postinfectious mechanisms have been described. Due to its rarity and non-specificity in imaging, the final diagnosis of IMT in the brain parenchyma relies on pathological examination. MANAGEMENT Treatment options are controversial and include total or subtotal removal, high-dose steroids, and radiation therapy. In the last decade, the development of ALK Tyrosine Kinase Inhibitors allows the possibility of chemotherapy in those patients harboring ALK mutations. CONCLUSION IMT is a rare tumor that can exceptionally be found in the CNS. The cause is still unknown although the different studies focus on a neoplastic origin. The diagnosis is based in the use of different modalities of imaging and with histological confirmation. Optimal management is gross total resection whenever possible, is the only established curative treatment. Further research with longer follow-up is needed to clarify the natural history of this rare tumor.

Abstract
Purpose Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal malignancy that occurs primarily in children and adolescents. The clinical and pathological features of IMT in adult patients are not well understood. Materials and Methods We retrospectively searched for records of adult patients with IMT at Fudan University Shanghai Cancer Center from 2006 to 2021. Clinicopathological data, treatments, and outcomes were collected and analyzed. Results Thirty adult patients with IMT, mostly women (60.0%), were included. The median age of the patients was 38 (21-77). The most common primary site was abdominopelvic region (53.3%), followed by lungs (20.0%). Seven patients had an abdominal epithelioid inflammatory myofibroblast sarcoma (EIMS). The positivity rate of anaplastic lymphoma kinase (ALK) was 81.5% (22/27). Sixteen patients with advanced ALK-positive disease received crizotinib, with an ORR of 81.3% and a disease control rate of 87.5%. The median PFS was 20.8 months. EIMS was associated with more aggressive behavior; however, the prognosis was similar to that of non-EIMS patients after treatment with an ALK inhibitor. At a median follow-up time of 30 months (95%CI 13.6-46.4), the 5-year overall survival was 77% (95% CI 66-88%) in all patients. Conclusion Adult IMTs appeared more aggressive, with a higher incidence of recurrence and metastases, and patients with EIMS had more aggressive cases. Treatment with ALK inhibitors resulted in a high ORR and a durable response, which suggested that ALK inhibitors could be used as a first-line treatment option in adult patients with ALK-positive advanced IMT.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a rare disease that mostly occurs in younger people and is located in the lungs in the general population. We report a rare case of adrenal IMT in a patient with HIV infection, which is believed to be the first of its kind worldwide. CASE PRESENTATION We present a rare case of a 44-year-old man with HIV infection who was diagnosed with adrenal IMT. The patient refused regular highly active antiretroviral therapy 13 years ago until he was admitted to hospital after an adrenal mass was found. The patient underwent successful computed-tomography-guided needle biopsy, and pathological analysis showed fibroblastic-myofibroblastic proliferation with inflammatory infiltration, which confirmed a diagnosis of IMT. We failed to perform complete resection of the tumor because of its diffuse invasion. The patient was complicated with severe multiple pulmonary infections postoperatively because of immunodeficiency, which eventually caused his death 2 months later. CONCLUSION Differential diagnosis of IMT is difficult, and tumor biopsy is an essential means of diagnosis. Surgical resection is preferred for both adrenal and HIV-related IMTs. Conservative treatment should be considered when there are technical difficulties with complete resection, and most patients have achieved good outcomes. However, more cases and longer follow-up are warranted to confirm long-term outcomes of HIV-related IMT.

Abstract
BACKGROUND An inflammatory myofibroblastic tumor (IMT) occurring in the central nervous system is very rare, and thus its pathogenesis is unknown. This case report and literature review aimed to explore the pathogenesis, clinical features, imaging findings, pathological characteristics, immunohistochemical characteristics, diagnoses, treatments, and risks of postoperative recurrence of IMT in the central nervous system.
CASE SUMMARY A 67-year-old woman was admitted to the hospital with an exophthalmic protrusion and double vision in the left eye that had persisted for 3 mo. Magnetic resonance imaging (MRI) showed a 2.4 cm × 1.3 cm heterogeneous large mass in the bottom of the left anterior cranial fossa, which was closely related to the dura mater. Before surgery, we suspected the mass to be meningioma. The entire mass was successfully removed under neuronavigation and electrophysiological monitoring, and postoperative pathology indicated an IMT with extensive infiltration of chronic inflammatory cells and scattered multinucleated giant cells. Head MRI at the 3-mo follow-up showed that the tumor at the bottom of left anterior cranial fossa had been completely resected without recurrence.
CONCLUSION From the histological, immunohistochemical, and genetic analyses, the present case suggests that the pathogenesis of IMT-CNS is related to autoimmunity.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a rare central nervous system (CNS) tumor. We first report a rare case of IMT in the lateral ventricle and describe the magnetic resonance imaging (MRI) findings of the tumor with an emphasis on the advanced MRI features. CASE PRESENTATION A 49-year-old female patient with headaches and blurred vision for 2 months. Brain MRI revealed a well-circumscribed, lobulated mass occupying the left lateral ventricle trigone, with marked perilesional brain edema. The tumor showed heterogeneous significant hyperintensity on T2-weighted imaging (T2WI) and hypointensity on T1-weighted imaging (T1WI). After the administration of gadolinium, the mass exhibited marked contrast enhancement and the halo sign was observed. On advanced MRI, the lesion showed decreased perfusion on perfusion MRI and reduced diffusion on diffusion-weighted imaging (DWI). On susceptibility-weighted imaging (SWI), there was a punctate low signal intensity in the tumor. The patient underwent surgical resection of the mass and a pathological examination confirmed the lesion to be an inflammatory myofibroblastic tumor with negative expression of anaplastic lymphoma kinase (ALK). This patient had remained healthy without evidence of recurrence during a 20-month follow-up. CONCLUSIONS On MRI, marked perilesional brain edema, significant hyperintensity on T2WI, hypoperfusion on perfusion MRI but with an obvious enhancement, no diffusion restriction on DWI, and halo sign may be the characteristic findings of intraventricular IMT. The advanced MRI characteristics could provide abundant information to reflect the histological features and physiological metabolic characteristics of the tumor.

Abstract
Inflammatory myofibroblastic tumor (IMT) prevalence is less than one in a million. Anaplastic lymphoma kinase (ALK)-positive IMT in the greater omentum and with a diameter greater than 8 cm is extremely rare. Here, we present a case and provide a brief literature review. A 4-year-old female was referred to our hospital with a 1-month history of intermittent fever. Computed tomography revealed a 6.4 × 5.5 × 6.5-cm lesion between the spleen and stomach. During the operation, we confirmed that the mass originated in the greater omentum and completely resected the mass, achieving a negative margin. The maximum cross-sectional area of the tumor after surgery was 8.3 × 7.5 cm. The immunohistochemistry result of this IMT was ALK (+), S100 (-), Ki-67+ (20%), Desmin (+), CD21 (-), CD35 (+), Vim (+), and SMA (+). The final pathology was IMT. No local recurrence or metastasis has been observed in the 8 months of follow-up.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor in the liver (IMTL) is a rare borderline mesenchymal tumor. Neither clinical symptoms nor laboratory tests have absolute specificity for the diagnosis of IMTL, and imaging also lacks obvious specificity. Although there are sporadic reports of recurrence after surgical treatment, surgical resection is the mainstay of treatment.
CASE SUMMARY A 29-year-old man complained of general weakness, slight discomfort in the upper abdomen, with a history of upper respiratory tract infection for 1 wk before admission. Plain and enhanced upper abdominal magnetic resonance imaging showed a mass in liver segments II and III (48 mm × 53 mm). He was treated by laparoscopic left lateral segmentectomy. Postoperative pathological examination with hematoxylin and eosin staining suggested that the mass in liver segments II and III was IMTL. During 21 mo postoperative follow-up, no obvious residual or recurrent lesions were observed.
CONCLUSION There is a risk of malignant degeneration in IMTL. The principal choice of treatment is laparoscopic left lateral segmentectomy.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor with recurrent potential, most commonly occurring in the lung but rarely in the kidney with nonspecific clinical symptoms and radiographic features, thus may be misdiagnosed as primary malignant lesions. We described a 6-year-old boy with renal IMT misdiagnosed as Wilms' tumor and then treated with right nephrectomy. It should be emphasized that in addition to the most common renal tumors in children, IMT should also be taken as a differential diagnosis. It is therefore mandatory to carry out clinical interpretation, careful histologic examination, and immunohistochemical studies collectively to make solid diagnosis.

Abstract
BACKGROUND A biliary inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymoma that, although it has a broad age spectrum, usually occurs in adults. Diagnosis is difficult because biliary IMTs often exhibit nonspecific clinical symptoms and imaging features, resulting in delayed or inappropriate treatment. Although most IMTs are benign, some show malignant properties such as infiltration, recurrence, and metastasis.
CASE SUMMARY Here, we retrospectively describe a 10-month-old infant who was admitted to our hospital due to stubborn jaundice. The patient responded poorly to routine medical treatment and his clinical manifestations and laboratory tests lacked specificity, so we turned to repeated ultrasound scans and other imaging examinations. As both hepatosplenic ultrasonography and diffusion-weighted magnetic resonance imaging demonstrated a space-occupying lesion, an exploratory laparotomy was performed. The final diagnosis made over two mo after the disease onset was infant biliary cirrhosis caused by a biliary IMT, which partially infiltrated into the liver. This infant is the youngest case of biliary IMTs that has been reported till now. The patient underwent an incomplete resection of the mass and Kasai Portoenterostomy. However, because of cirrhosis, he also received a paternal liver transplant. Since some IMTs show malignant properties, we proceeded with a three-year of follow-up; however, no recurrence or metastasis has been noted.
CONCLUSION Neoplastic disease such as IMTs should be considered when routine medical treatment of obstructive jaundice is not successful. Observation of dynamic imaging changes is helpful for diagnosis. Periodic follow-up is necessary for IMTs.

We report 7 cases of an indolent, variably myxoid tumor of the vocal cords, characterized by overt cellular atypia with large cells containing intranuclear and intracytoplasmic vacuoles, delicate curvilinear vessels, and sparse inflammatory infiltrate. Six patients were male, aged 15 to 65 years, and 1 patient was a 54-year-old female. All tumors were located in the superficial portion of the vocal cord. One patient suffered a recurrence that was completely resected; all patients with available follow-up data currently have no evidence of disease. The tumors contained alternating areas with myxoid stroma and more compacted regions with tumor cells organized in short fascicles, interwoven with delicate curvilinear vasculature. Overt cellular atypia with large cells containing intranuclear and intracytoplasmic vacuoles or resembling ganglion cells was present in all cases but mitoses and necrosis were absent. ALK immunostaining was positive in all cases, while most tumors were negative for smooth muscle actin. Targeted RNA-sequencing revealed an identical TIMP3::ALK fusion with exon 1 of TIMP3 gene being fused with exon 12 of ALK gene in all analyzable cases. For various reasons discussed, it remains unclear whether this tumor represents a mere subtype of IMT or a separate entity. Nevertheless, it is a morphologically distinct and diagnostically challenging lesion that needs to be recognized by surgical pathologists in order to prevent overdiagnosis in this clinically very delicate area.

Abstract
Background: Inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm with unknown etiology and recurrent potential. They are widely reported in children and young adults. Nearly 50% of inflammatory myofibroblastic tumor harbor rearrangement in anaplastic lymphoma kinase (ALK) gene with the majority expressing ALK protein. ALK-negative IMTs harbor alteration in ROS1 gene in a subset of cases. Few reports have shown association of IMT with Epstein-Barr virus (EBV). Case report: We report a case of IMT of the spleen in an 18-month-old infant presenting with abdominal distention and failure to thrive. Workup for ALK-1, ROS1, and EBV small-encoded RNA in-situ hybridization using immunohistochemistry was negative. Conclusions: IMT can arise in an infant spleen.

Abstract
Mesenchymal tumors of the stomach are uncommon, with gastrointestinal stromal tumor (GIST) being the most common among them. Majority of the tumors may arise from cells of Cajal, smooth muscle cells, neural cells, totipotent stem cells, adipocytes or fibroblasts. Imaging plays an important role not only in staging but also in characterizing these tumors. Many of these tumors have characteristic imaging features. GISTs usually present as large cavitating and necrotic tumors with exophytic component. Presence of fat tissue within the tumor suggests a lipoma or a teratoma, early phase hyperenhancement indicates glomus tumor and hemangioma, and delayed contrast enhancement is seen in schwannoma. Their differentiation from epithelial tumors like carcinoma and neuroendocrine tumors is often possible based on the location (mesenchymal tumors are intramural), spread, morphological appearance and enhancement patterns. However, overlapping features exist between these tumors with imaging often being only suggestive. A biopsy is necessary for a definitive diagnosis in many cases.

Abstract
This review focuses on recent advances in epithelioid and myxoid uterine mesenchymal neoplasms, a category of tumors whereby diagnostic criteria have been rapidly evolving due to advances in molecular testing. Pertinent clinicopathological and molecular features are highlighted for perivascular epithelioid cell tumors, uterine tumors resembling ovarian sex cord tumors, BCOR/BCORL1-altered high-grade endometrial stromal sarcomas, and inflammatory myofibroblastic tumors. Novel developments in epithelioid and myxoid leiomyosarcomas are briefly discussed, and differential diagnoses with key diagnostic criteria are provided for morphologic mimickers.

Abstract
INTRODUCTION Inflammatory pseudotumor (IPT) and inflammatory myofibroblastic tumor (IMT) are two very rare entities that were formerly included in the same category; however, today they are considered two different diseases due to the neoplastic origin of the IMT. Our objective is to share our experience in the management of these two types of tumors that we must take into account in the differential diagnosis of pulmonary masses or nodules. METHODS Thirteen patients with a pathological diagnosis of IPT and IMT who underwent surgery between 2008 and 2019 were retrospectively studied. We recorded the pre and postoperative information of each one, as well as the survival analysis. RESULTS Of the 13 patients, 8 were men and 5 women. The mean age of presentation was 53,5 years. An atypical segmentectomy was performed in 6 patients; a lobectomy was necessary in 6 and a pneumonectomy in 1 case. In all cases a complete resection was achieved. Diagnosis was possible thanks to histology, immunohistochemical (IHQ) and fluorescent in situ hybridization (FISH) techniques determining the expression of IgG4 and the rearrangement of ALK, respectively. After a median follow up of 49 months, we didn't find any loco-regional or distant recurrence in the patients studied. CONCLUSION IPT and IMT are rare tumors with a very good prognostic. The diagnosis of both entities is based mainly on specific anatomopathological techniques. Surgery has, in most cases, both a diagnostic and therapeutic role.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm of intermediate malignancy. We describe the largest cohort of IMT patients to date, aiming to further characterize this rare, poorly understood tumor. This is a multi-institutional review of IMT patients ≤39 years, from 2000-2018, at 18 hospitals in the Pediatric Surgical Oncology Research Collaborative. 182 patients were identified with median age of 11 years. 33% of tumors were thoracic in origin. Presenting signs/symptoms included pain (29%), respiratory symptoms (25%), and constitutional symptoms (20%). Median tumor size was 3.9 cm. Anaplastic lymphoma kinase (ALK) overexpression was identified in 53% of patients. 7% of patients had distant disease at diagnosis. 91% of patients underwent resection: 14% received neoadjuvant treatment and 22% adjuvant treatment. 12% of patients received an ALK inhibitor. 66% of surgical patients had complete resection, with 20% positive microscopic margins, and 14% gross residual disease. Approximately 40% had en bloc resection of involved organs. Median follow-up time was 36 months. Overall 5-year survival (OS) was 95% and 5-year event-free survival (EFS) was 80%. Predictors of recurrence included respiratory symptoms, tumor size, and distant disease. Gross or microscopic margins were not associated with recurrence, suggesting that aggressive attempts at resection may not be warranted. This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND Inflammatory myofibroblastic tumors (IMTs) are defined as tumors composed of differentiated myofibroblastic spindle cells, usually accompanied by numerous plasma cells and lymphocytes, and classified as intermediate (occasionally metastatic) by the World Health Organization. Its pathogenesis and biological behavior have not yet been elucidated. Breast IMT is extremely rare, and prosthesis implantation combined with IMT has not been reported. This study reports a case of IMT following resection of a malignant phyllodes tumor of the left breast and implantation of a prosthesis.
CASE SUMMARY A 41-year-old female presented to our hospital with a mass in the left breast for 3 mo. The patient had undergone resection of a large mass in her left breast pathologically diagnosed as a malignant phyllodes tumor and implantation of a prosthesis five years prior. Ultrasonic examination revealed an oval mass in the left breast, and the patient underwent left breast mass resection and prosthesis removal. Light microscopy revealed the spindle cells to be diffusely proliferated, with a large number of neutrophils, lymphocytes, and plasma cell infiltration. Immunohistochemical staining revealed that the spindle cells were partially positive for smooth muscle actin, which is positive for BCL-2 and cluster of differentiation (CD) 99 but were negative for anaplastic lymphoma kinase, cytokeratin, S-100 protein, desmin, and CD34. The final diagnosis was IMT. No recurrence or metastasis was observed during the 5-year postoperative follow-up.
CONCLUSION Prosthesis implantation may be one of the causes of IMT, but further investigation is necessary to prove it.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare benign neoplasm with variable clinical presentation. We hereby present a case of a 27-year-old female who presented to us with an unsuspecting gingival overgrowth in her anterior gingiva. This article aims to describe IMT as a rare intraoral entity which may involve the anterior maxillary gingiva, involving or sparing the underlying bone, as only a handful of such cases have been reported so far. Surgical excision is the mainstay of treatment. Biopsy and histopathological examination of even the smallest lesions is a must. Timely diagnosis and intervention can prevent severe morbidity that can arise if these lesions are left undiagnosed as aggressive management of lesions that become extensive is mandatory.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm of children and young adults. It consists of myofibroblastic cells of borderline malignancy admixed with inflammatory cells. According to the WHO classification, of tumors, it is a soft-tissue tumor with an intermediate malignant potential. It may arise within numerous organs. Ureteral location is exceedingly rare. We report the exceptional case of a 4-year-old boy presenting with a giant right ureteral IMT removed during a nephroureterectomy. Histology and immunohistochemistry confirmed the diagnosis of an IMT with ALK-1 expression. A seven months follow-up showed no recurrence or distant metastasis. We also reviewed the literature for similar cases of pediatric ureteral IMT.

Abstract
An inflammatory myofibroblastic tumor (IMT) is a rare tumor that is currently classified as an intermediate cancer according to the World Health Organization classification system. The pathophysiology of its occurrence is still unknown. Imaging tests, such as CT or MRI, can be helpful in diagnosis, but the final diagnosis is confirmed by a pathological examination through a biopsy and immunohistochemistry stain. The patient, in this case, presented an asymptomatic intrahepatic mass discovered incidentally on an imaging examination. Initially, intrahepatic cholangiocarcinoma was suspected, but she was finally diagnosed with IMT through a histological examination after a liver resection.

Abstract
INTRODUCTION Inflammatory myofibroblastic tumor (IMT) of the trachea is rare tumor mostly found in children and young adults. CASE REPORT We report a case of a 28 year-old woman who presented chronic isolated coughing. Chest CT scan showed a tracheal tumor. Rigid bronchoscopy allowed the complete removal of the tumor, and histology confirmed the diagnosis of IMT. 12 months follow-up found no recurrence. DISCUSSION IMT is a rare tumor exhibiting both benign and aggressive behaviour. The endoscopic approach of tracheal should be considered when there is a minimal tracheal wall invasion. CONCLUSION Through this case, we want to emphasise the role of rigid bronchoscopy in the complete removal of endotracheal IMT.

Abstract
Mediastinal masses span a wide histopathological spectrum. Inflammatory pseudotumors are rare and most commonly described in the lungs but these are reported in almost all the organs in the body. Mediastinal involvement is rare and difficult to diagnose. Clinical manifestations and laboratory investigations and radiology are non-specific. Histomorphology and Immunohistochemistry provide a valuable aid. Complete resection usually provides definitive diagnosis and is treatment of choice.

Abstract
BACKGROUND Inflammatory myofibroblastic tumors (IMTs) are a rare subtype of inflammatory pseudotumor frequently associated with rearrangement of the anaplastic lymphoma kinase (ALK) gene. Their treatment has historically relied on at-times challenging and morbid surgical excision. Recent studies have shown that neo/adjuvant therapy with ALK inhibitors can significantly enhance outcomes in select patients. METHODS A systematic literature review was performed to characterize comprehensive treatment of ALK-positive IMTs in the pediatric population. This report also includes two patients from our home institutions not previously reported in the literature. RESULTS We identified a total of 27 patients in 12 studies in addition to 2 patients from the senior authors' institution for a total of 29 patients (median age, 7 years; 52% male). The IMTs comprised a wide range of anatomic locations. Almost half (12, 41.3%) were treated with ALK-inhibitors alone and felt to be in remission. The remainder was treated with ALK-inhibitors either before or after surgery and had a curative response. CONCLUSIONS ALK-positive IMTs can be successfully treated with ALK-inhibition alone or in combination with surgical resection. Further genetic characterization may be helpful in determining more precise treatment and defining needed durations thereof.
