Pediatric laryngeal inflammatory myofibroblastic tumour: Case report and systematic review of the literature

A B S T R A C T Introduction: Inflammatory myofibroblastic tumours (IMT) are rare benign neoplasms in the pediatric population, found most frequently in the lungs with rare reports of laryngeal involvement. The aim of this paper is to present a clinical case of laryngeal IMT followed by a systematic review on pediatric laryngeal IMT. Case Report: We present the case and the management of a 13-year-old boy with a laryngeal IMT Material and Methods: A comprehensive review of literature was conducted in September 2019 using Pubmed and Scopus. Included articles were reviewed for mean age at presentation, gender, main symptoms, treatment modality, histopathological features and follow-up Results: Sixteen cases of pediatric laryngeal IMT were reported in the literature. The mean age of presentation was 7 years; endoscopic surgical resection was used in 87% of procedures, and the mean number of interventions needed to achieve remission was 1.6. Conclusions: Pediatric laryngeal IMT are rare benign proliferations with only 16 reported case in the medical literature. The diagnosis of this entity remains a challenge and the standard of care is surgery with clear margins. (c) 2020 Oto-Rhino-Laryngological Society of Japan Inc. Published by Elsevier B.V.
