Acute Respiratory Distress in Patient with Laryngeal Schwannoma

Schwannoma is a neurogenic benign tumour arising from the proliferation of Schwann cells present in the peripheral nerve sheath of myelinated nerves. This proliferation can hypothetically appear in every anatomic region of the human body, but the nerve sheath tumors rarely occur within the larynx. In this paper the authors discuss the case of a 74-year-old female who presented to Emergency Unit (EU) for an important acute respiratory distress. Airway flexible endoscopy revealed a bulky mass of the aryepiglottic fold measuring 3.5 cm in diameter. The patient underwent tracheotomy and a single-step surgical excision treatment of the mass which was recognized as a schwannoma at pathological examination. Tracheotomy was closed 2 weeks postoperatively. After 18 months of followup, the patient is alive and free of disease and her voice had improved markedly.
