Abstract
Introduction: Tracheal tumors are rare in the pediatric population. Primary tumors within the trachea often present with non-specific symptoms during the initial stages, leading to a delayed diagnosis. Prompt diagnosis of a tracheal tumor is crucial due to the risk of life-threatening airway obstruction it poses. This article discusses the case of a twelve-year-old girl who experienced 8years of breathing difficulties without an adequate response to treatment. Case Presentation: The patient was referred to Mofid Children's Hospital after experiencing 8 years of difficulty with dyspnea. Her dyspnea was classified as functional class 2 and was accompanied by dry coughs. Additionally, a biphasic stridor was observed during her auscultation. Further investigations revealed an intra-tracheal mass, identified as a mucous gland adenoma (MGA). Imaging and pathology showed no signs of malignancy. Following her surgery, she was completely free of symptoms, and her follow-up spirometry showed no abnormalities. Conclusions: In this article, we present a detailed case of MGA. Despite the low incidence of intra-tracheal tumors, conducting further studies in patients who respond poorly to treatment is crucial. The potential complications from these tumors can be catastrophic. Thus, enhancing our knowledge and expertise in this area is of great importance.
