Decoding a Rare Benign Laryngeal Tumor: A Case Report

Benign laryngeal tumors are rare and often difficult to diagnose clinically due to nonspecific symptoms and resemblance to other lesions. This case report describes a middle-aged male presented to ENT OPD with history of persistent change of voice for 4 years, hoarse in nature, progressive and difficulty in breathing for past 1 month, more while lying down in supine position and is progressive. Large benign neoplasm arising from the right pyriform fossa, presenting with progressive hoarseness and recent onset of inspiratory stridor. Endoscopic evaluation revealed a smooth submucosal mass obscuring the laryngeal inlet, while contrast-enhanced CT showed a well-defined supraglottic lesion causing significant airway narrowing without features of malignancy. The patient underwent successful transoral microlaryngeal excision following fiberoptic-guided intubation. Postoperatively, temporary tracheostomy was required due to airway compromise. Histopathology confirmed schwannoma, characterized by Antoni A and B areas with Verocay bodies. The patient recovered well, with decannulation after one week and normal vocal cord mobility at six months. This case highlights the importance of airway management and demonstrates that large laryngeal schwannomas can be effectively managed with minimally invasive transoral excision, avoiding the morbidity associated with open surgical approaches.
