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
Inflammatory myofibroblastic tumour of the heart is an exceedingly rare benign neoplasm. While benign, without prompt management its impact can be devastating. Tetralogy of Fallot with absent pulmonary valve is a rare form of CHD. We present the first documented case of inflammatory myofibroblastic tumour of the heart in the presence of tetralogy of Fallot with absent pulmonary valve.

Anaplastic Lymphoma Kinase Inhibitor in Treatment of Inflammatory Myofibroblastic Tumor of the Tongue in Infancy. J Pediatr Hematol Oncol 2021; 43:e521-e524.

Abstract
Inflammatory myofibroblastic tumors (IMTs) are rare in neonates. IMTs of the tongue are also very rare in infancy, with only 1 case reported in this age group. The mainstay of therapy has traditionally been surgery, which can be devastating to surrounding structures and negatively impact prognosis. Approximately 50% of IMTs harbor a translocation involving the anaplastic lymphoma kinase gene. We describe a case of IMT of the tongue in a neonate treated with debulking and an anaplastic lymphoma kinase inhibitor. The patient achieved complete response and remains disease-free 1.5 year following completion of therapy.

Abstract
We report a case of inflammatory myofibroblastic tumor affecting the pulmonary artery in a 15-year-old male, presenting with a clinical scenario of recurrent pulmonary embolisms. During diagnostic workup for persistent fever, a mass in main pulmonary artery was detected at echocardiography and confirmed at angio-CT scan. The patient underwent a first successful surgical resection and discharged home with no echocardiographic evidence of residual lesions, but, after 5 months, he was admitted for hemoptysis and an angio CT-scan showed a mass in right pulmonary artery with multiple distal perfusion defects, suspicious for both thrombotic and secondary lesions. To prevent further embolisms, the patient was scheduled for a second surgical procedure, which allowed a complete removal of the tumor from major branches of right pulmonary arteries. Our experience highlights that, despite of its intermediate malignancy, inflammatory myofibroblastic tumor may behave as an extremely dangerous condition, requiring multiple surgeries an integrated and multidisciplinary approach.

Infantile inflammatory myofibroblastic tumors: clinicopathological and molecular characterization of 12 cases. Mod Pathol 2020; 33:576-590. [PMID: 31690781 DOI: 10.1038/s41379-019-0406-6] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 10/06/2019] [Accepted: 10/07/2019] [Indexed: 12/17/2022]
Abstract
Inflammatory myofibroblastic tumors arising in infants are rare, poorly investigated and mostly reported as isolated cases or as a part of larger series thus, their clinicopathological and molecular features are essentially unknown. Archival files from two large pediatric institutions and a tumor registry were queried for pediatric inflammatory myofibroblastic tumors. Available material from patients ≤12 months of age was reviewed. Additional immunostains (ALK-1, D240, WT1) and ALK-FISH studies were performed as needed. Targeted anchored multiplex PCR with next-generation sequencing was done in all cases. A total of 12 of 131 infantile cases (mean 5.5 months) were identified (M:F of 2:1). Anatomic locations included intestinal/mesenteric (n = 6), head/neck (n = 3), and viscera (n = 3). Half of tumors showed a hypocellular myxoid pattern, perivascular condensation, and prominent vasculature with vague glomeruloid structures present in four of them. The remaining cases exhibited a more cellular pattern with minimal myxoid component. ALK-1 immunohistochemistry was positive in most cases (11/12) with cytoplasmic-diffuse (n = 6), cytoplasmic-granular (n = 2), and dot-like (n = 3) staining patterns. ALK fusion partners identified in five cases included EML4, TPM4, RANBP2, and a novel KLC1. Three inflammatory myofibroblastic tumors showed fusions with other kinases including TFG-ROS1 and novel FN1-ROS1 and RBPMS-NTRK3 rearrangements. Favorable outcome was documented in most cases (10/11) with available follow-up (median 17 months) while three patients were successfully treated with crizotinib. In summary, infantile inflammatory myofibroblastic tumors are rare and can exhibit paucicellular, extensively myxoid/vascular morphology with peculiar immunophenotype mimicking other mesenchymal or vascular lesions. All tumors harbored kinase fusions involving ALK, ROS1, and NTRK3 including three novel fusion partners (KLC1, FN1, and RBPMS, respectively). A favorable response to crizotinib seen in three cases supports its potential use in infants as seen in older patients. Awareness of these unusual morphologic, immunophenotypic, and molecular features is critical for appropriate diagnosis and optimized targeted therapy.

Abstract
Herein, we present the case of a 66-year-old man with an inflammatory myofibroblastic tumour. An inflammatory myofibroblastic tumour is an extremely rare entity, with only 60 cases having been reported to date in the literature. The origin of this type of tumour is unknown and the treatment of choice is surgical resection. We present the surgical technique of our case and a review of the literature regarding this tumour. This is the first case described in a man above 60 years of age with a tumour located in the right ventricle.
