Rare Case of Pediatric Upper Airway Obstruction: Laryngeal Granular Cell Tumor.

Granular cell tumors (GCTs) are uncommon neoplasms of unknown origin that can manifest in multiple locations throughout the body. Physicians should be aware of this type of tumor presenting in unusual locations such as the larynx, particularly in pediatric patients with stridor and dysphonia. We describe an 11-year-old female with a large laryngeal mass that obstructed the majority of the laryngeal lumen. A tracheotomy was performed to secure the patient's airway, followed by a direct suspension laryngoscopy, during which the mass was excised in its entirety. The biopsied mass was histopathologically and immunohistochemically examined to confirm the diagnosis of granular cell tumor. She benefited from treatment and experienced a favorable outcome. This case report emphasizes the critical nature of properly diagnosing this type of tumor in patients who present with vocal or respiratory symptoms.
