  ABSTRACT: The common causes of stridor in adults are abscesses or swelling of the upper airway, tumors, paralysis, or malfunction of vocal cords. Tracheitis due to immunoglobulin deficiency may be a rare explanation for stridor in adults, although occasionally reported in children. We report an adult man having stridor secondary to isolated immunoglobulin A deficiency. We did an in-depth review of the literature to seek out no reported cases of stridor thanks to immunoglobulin deficiency in adults. This case underlines the very fact that a standard symptom like stridor rarely occurs thanks to uncommon causes. This case is exclusive because it reports the presence of stridor associated with isolated immunoglobulin A deficiency in an adult patient. The explanation for the stridor was an intraluminal narrowing of the upper part of the extrathoracic trachea.
