Subglottic concretion masquerading as foreign body in a child with β thalassemia major: an airway nightmare!

Subglottic concretion is a rare and perilous condition usually presenting with existing or impending airway obstruction. Due to long-standing nature of the condition, slow progression of symptoms and rarity of occurrence, the condition is either missed or misdiagnosed. Its resemblance in presentation and symptoms to that of foreign body (FB) bronchus can lead to a diagnostic misadventure. Detailed history, chronology of symptoms and radiological imaging in conjunction with fiberoptic evaluation are keys for establishing correct diagnosis. Treatment outcomes in such cases depend on appropriate management approach with backup plan in tandem. We describe a child with β thalassemia major with subglottic concretion, which was erroneously diagnosed and managed as a case of subglottic FB due to its classical history and presentation. The aim is to highlight the circumstances leading to this diagnostic misadventure with emphasis on airway management, problems faced and lessons learnt during the same.
