Inflammatory myofibroblastic tumor (IMT) is a rare soft tissue tumor characterized by proliferation of fibroblastic cells associated with an inflammatory infiltrate. Inflammatory myofibroblastic tumors have a predilection for the pediatric population and are usually found in the lung parenchyma but rarely at the carina. They rarely metastasize but can be locally destructive. Surgical resection is the cornerstone of therapy, which results in excellent survival despite risk of local recurrence. We present the case of a nine-year-old girl with an IMT mass at the carina and obstructing the left main stem bronchus, requiring extensive resection and reconstruction.

Inflammatory myofibroblastic tumor (IMT) is a rare tumor type with a prognosis ranging from benign to locally aggressive. Initially described as a reactive lesion most commonly of the lungs, cases of IMT have now been reported in rare instances in the head and neck, which may be more aggressive than other tumor locations. IMT frequently afflicts children and adolescents, but pediatric cases of IMT in the head and neck region are rare.

Dermal white adipose tissue (dWAT), distinguished by its origin from cells within the dermis and independence from subcutaneous fat tissue, has garnered significant attention for its non-metabolic functions. Characterized by strong communication with other components of the skin, dWAT mediates the proliferation and recruitment of various cell types by releasing adipogenic and inflammatory factors. Here, we focus on the modulatory role of dWAT at different stages during wound healing, highlighting its ability to mediate the adipocyte-to-myofibroblast transition which plays a pivotal role in the physiology and pathology processes of skin fibrosis, scarring, and aging.

Inflammatory myofibroblastic tumors (IMTs) are rare mesenchymal neoplasms characterized by spindle-cell morphology with accompanying inflammatory infiltrates. Originally described in 1939, these tumors can arise in various anatomic locations, with the urinary bladder being a rare site of occurrence but the most common within the genitourinary tract. IMTs typically present as polypoid masses or firm submucosal nodules, often with painless hematuria in bladder cases.

Tracheal tumors in pediatric patients are rare, accounting for 2% of all airway abnormalities and 0.2% of all pediatric tumors. Diagnosis is often delayed due to the heterogeneity of presenting symptoms, such as stridor and wheezing, which are frequently misattributed to other conditions.

Uterine mesenchymal tumors are a diverse group of tumors that can display a broad range of morphologic, immunohistochemical, and molecular profiles and are associated with varied clinical behaviors. In recent years, they have increasingly been classified by their underlying molecular alterations, leading to a more precise separation of diagnostic entities. As their diagnostic criteria have been refined, so too have the features that can be used to predict clinical outcomes.
