Abstract

Inflammatory myofibroblastic tumor (IMT) is a very rare mesenchymal tumor that can behave as a locally benign or aggressive lesion. Here, we present an extremely rare case of IMT involving the subglottic of a middle-aged male. Steroid therapy treatment alleviated dyspnea, but the recurrence of dyspnea was reported two months later. Both sides of the subglottic tumor were excised following treatment, and the surgical specimens were subjected to histopathological evaluation and diagnosis for IMT. At 4 years after excision, follow-up laryngoscopy revealed symmetric vocal cords without evidence of any subglottic mass. Subglottic mass is often asymptomatic until it presents with hoarseness or dyspnea, and subglottic IMT is rare. Based on the successful treatment of our case, complete surgical excision is highly recommended for this rare tumor. However, further research is needed to discover a more effective and cost-effective treatment approach.
