Obligate mouth breathing during exercise. Nasal and laryngeal sarcoidosis.

A young black man presented with simultaneous nasal and laryngeal sarcoidosis, each uncommon entities. Despite severe upper airway obstruction and emergent tracheostomy, there was an uncharacteristic rapid response to oral steroids alone. The patient's predominant initial complaint of early mouth breathing during routine army physical training demonstrates a symptom complex and an alternate mechanism of dyspnea to consider in sarcoidosis.
