Hidden Diagnosis in the Subglottic Larynx: Schwannoma Mimicking as Bronchial Asthma

Schwannomas are rare neurogenic tumors derived from the schwann cells. Their laryngeal location is uncommon and the diagnosis is difficult. We report a case of a 17-year-old female who presented with symptoms of intermittent breathlessness mimicking acute attacks of bronchial asthma and resulted in delayed diagnosis, which lead to upper airway obstruction and an emergency tracheostomy. Computed tomography (CT) of neck revealed a soft-tissue mass within the subglottic region. Surgical excision of the growth was done by laryngofissure technique. Histopathological examination of the tumor revealed it to be a schawanoma. The subglottic occurrence of schwannoma is very rare. Case history and detailed clinical examination are important and will guide for relevant investigations and help to reach at a definitive diagnosis.
