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.
