RNA Sequencing of Discarded Tracheal Stenosis Tissue to Characterize Cellular and Molecular Pathogenesis

RNA Sequencing of Discarded Tracheal Stenosis Tissue to Characterize Cellular and Molecular Pathogenesis

Benign tracheal stenosis is a rare but potentially life-threatening condition, typically resulting from fibroinflammatory scarring. It can be secondary to iatrogenic etiologies such as intubation or tracheostomy , as well as autoimmune diseases and being idiopathic. Patients typically undergoes endoscopic or surgical interventions to open up the airways. This project will analyze resected or biopsied tissue from patients with benign tracheal stenosis to define disease-specific RNA expression profiles.

Inclusion Criteria:

• Patients with benign tracheal stenosis

Exclusion Criteria:

• Malignancy. active infection
