Abstract
Background Hepatic inflammatory myofibroblastic tumor (IMT) is an infrequent tumor with potential malignancy. However, it lacks specific clinical symptoms and usual imaging features. Case presentation A 34-year-old woman had a six-month history of fever and on-and-off pain in the upper right part of her abdomen that lasted for two weeks. Imaging tests revealed a liver mass initially thought to be liver malignancy, but subsequent histopathological examination after liver removal confirmed the diagnosis as hepatocellular inflammatory myofibroblastic tumor (HIMT). Conclusion Hepatic inflammatory myofibroblastic tumor (IMT) is an uncommon growth with vague clinical symptoms and lab results. Surgical removal remains the primary treatment method, resulting in favorable prognostic outcomes.

Abstract
An inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal neoplasm of borderline malignant potential. Nearly half of all IMTs have rearrangement of anaplastic lymphoma kinase (ALK) locus on chromosome 2p23 which can be treated with targeted therapy. Herein, we describe an unusual presentation of IMT involving an anatomical region rarely implicated in this disease process. A 15-year-old male patient came to the ER with dysphagia and coffee ground emesis. On esophagogastroscopy, a nodular luminal obstructing 30 × 50 mm mass in the lower esophagus was found, which was continuous with a large, partially circumferential gastric mass extending from the mid-body to the proximal antrum. Biopsies from esophageal and gastric masses revealed submucosal lesions composed of cytologically bland spindle and epithelioid cells, intermingled with inflammatory infiltrate, for which several immunohistochemical (IHC) stains were performed. The molecular study demonstrated ATIC::ALK fusion. Based on morphological, IHC, and molecular study findings, the diagnosis of ALK-positive IMT was rendered. Because surgical excision was deemed infeasible, the patient was started on ALK-inhibiting therapy with crizotinib. The patient responded well with no evidence of residual or recurrent disease on follow-up imaging or surveillance esophagogastroduodenoscopy. Crizotinib was ultimately discontinued after 10 months of therapy, and the patient continues to undergo surveillance imaging for monitoring of disease burden.

Liver transplantation for hilar inflammatory myofibroblastic tumor: Case report and review of the literature. Pediatr Transplant 2022; 27:e14445.

Abstract
BACKGROUND Inflammatory myofibroblastic tumors (IMTs) of the liver are rare neoplasms. These tumors are difficult to distinguish from other neoplasms by radiological examination, have uncertain evolution, and there is no consensus on the treatment of these lesions. Hilar tumors can involve the portal vein, hepatic artery, bile duct, and spread to the branches of the portal triad, causing obstructive symptoms, occlusive phlebitis, and portal hypertension. Thus, liver transplantation (LT) is an excellent alternative for locally advanced hilar tumors, since it ensures complete tumor resection with free margins. METHODS/RESULTS We present a literature review and a case report showing a 3-year-old boy with liver IMT invading the hepatic hilum and inferior vena cava, who underwent a successful living donor liver transplantation that required portal vein and vena cava replacement. CONCLUSION The incidence of hilar IMTs is low and there is no well-established standard treatment. Liver transplantation for a hilar tumor with vascular invasion was acceptable in this case because the radically of the surgery was the key for the cure, and because the tumor was benign in nature.

Abstract
Background Inflammatory myofibroblastic tumor (IMT) is a very rare tumor and occurs seldom in the biliary tract. IMT can occur in any part of the body and in people of any age; however, it most commonly occurs in children or adolescents. Its etiology and pathogenesis are currently unknown. The clinical manifestations of a hilar inflammatory myofibroblastic tumor are atypical, and the imaging examination is nonspecific. The diagnosis is mainly based on histopathology and immunohistochemistry findings, and surgical resection is the preferred treatment method. Case Description Herein, we report a rare case of hilar bile duct IMT and review the related literature. Our patient was a 54-year-old woman presenting with a 1-day history of upper abdominal pain as the main clinical symptom. She was misdiagnosed as having cholangiocarcinoma before the surgery. She underwent surgery and was ultimately diagnosed with IMT based on histopathology and immunohistochemistry findings. On 1-year follow-up, no tumor recurrence or related complications were noted. Conclusions We hope this case report helps clinicians gain a deeper understanding of biliary IMT of the hilum.

Complicated course of biliary inflammatory myofibroblastic tumor mimicking hilar cholangiocarcinoma: A case report and literature review. World J Clin Cases 2021; 9:6155-6169. [PMID: 34368338 PMCID: PMC8316968 DOI: 10.12998/wjcc.v9.i21.6155] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 04/30/2021] [Accepted: 05/20/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The inflammatory myofibroblastic tumor (IMT) is a rare, idiopathic, usually benign, mass-forming disease with myofibroblastic proliferation and a varying amount of inflammatory cells. Although it can affect various organs, the biliary tract is a rare localization of primary IMT, clinically, endoscopically and radiologically imitating cholangiocarcinoma. The treatment options are based only on clinical practice experience.
CASE SUMMARY A 70-year-old woman was referred to our center due to progressive fatigue, weight loss, abdominal pain, night sweats, and elevated liver enzymes. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP) revealed proximal common hepatic duct and hilar biliary strictures extending bilaterally to lobular bile ducts. Although initial clinical, endoscopic and radiological signs were typical for hilar cholangiocarcinoma, histological examination showed no signs of malignancy. In total, 8 biopsies using different approaches were performed (several biopsies from dominant stricture during ERCP and direct cholangioscopy; ultrasound-guided liver biopsy; diagnostic laparoscopy with liver and lymph node biopsies). Histological examination revealed signs of IMT, and the final diagnosis of biliary IMT was stated. Although IMT is usually a benign disease, in our case, it was complicated. All pharmacological treatment measures were ineffective. The patient still needs permanent stenting, suffers from recurrent infections and mechanical jaundice. Despite that, the patient already survived 24 mo.
CONCLUSION IMT presenting with hilar biliary strictures is a unique diagnostic and clinical challenge as it is indistinguishable from cholangiocarcinoma, and there are no evidence-based treatment options. Our goal is to increase the understanding of this rare disease and its possible course.

Abstract
UNLABELLED Inflammatory myofibroblastic tumour usually has a benign course and is very rarely associated with the heart. It can have life-threatening consequences, depending on its position or the presence of aggressive and metastatic complications. A 3-month-old boy presented with pericardial tamponade and was diagnosed with intrapericardial inflammatory myofibroblastic tumour associated with Coronavirus OC43. A large tumour attached to the left ventricle was completely removed by surgical resection and he made a full recovery. ABBREVIATIONS ALK: anaplastic lymphoma kinase; CMV: cytomegalovirus; CRP: C-reactive protein; EB: Epstein-Barr virus; ESR: erythrocyte sedimentation rate; IM: inflammatory myofibroblastic tumour; NSAI: non-steroidal anti-inflammatory drugs; PTFE: polytetrafluoroethylene; SMA: smooth muscle actin.
