INTRODUCTION
Subglottic stenosis (SGS) is a component of laryngotracheal stenosis that involves the narrowing of the airway below the vocal cords. Symptoms of SGS include wheezing, dyspnea, hoarseness, stridor, and, in severe cases, asphyxiation [1,2]. It may be caused by congenital, acquired, or iatrogenic factors, with acquired cases often attributed to infection, trauma, or idiopathic causes [3]. In patients with laryngotracheal stenosis, the most common cause is iatrogenic factors, accounting for 54.7% of cases, with 59% developing subglottic stenosis [4]. Autoimmune diseases are one of the less common causes of SGS and include granulomatosis polyangiitis, relapsing polychondritis, inflammatory bowel disorders, rheumatoid arthritis, sarcoidosis, and amyloidosis. A diagnosis of idiopathic SGS is made when there is no identifiable underlying systemic disease, and it is typically a diagnosis of exclusion. Despite the availability of effective endoscopic and open surgical interventions, the inflammatory aspect of the condition continues to hinder many patients from achieving complete remission [2]. A detailed medical history is essential for patients with respiratory issues because misidentifying the condition can lead to treatment delays and life-threatening consequences.
Our study aimed to report an atypical subglottic stenosis associated with spondyloarthropathy. While this condition is commonly associated with various etiologies, such as trauma, iatrogenic factors, or idiopathic causes, its occurrence in the context of spondyloarthropathy remains relatively less understood. This case report sheds light on the importance of early recognition and management to improve the quality of life of affected individuals.
