A 9-year-old, vaccinated boy with glucose-6-phosphate dehydrogenase deficiency and β-thalassemia trait presented with 1 month of progressive dyspnea, snoring, dysphagia, and weight loss. Both parents had a history of latent tuberculosis infection treated after immigrating to the US from Syria shortly after the patient's birth. The patient's pediatrician diagnosed him with reactive airway disease and adenotonsillar hypertrophy. He was referred to the otolaryngology clinic, where flexible laryngoscopy revealed diffuse upper airway lymphoid hyperplasia and supraglottic edema. He was sent to the emergency department, where he was stridulous and afebrile with a normal white blood cell count and an elevated erythrocyte sedimentation rate. A computed tomography scan of the neck revealed diffuse edema and contrast enhancement of the nasopharynx, oropharynx, hypopharynx, and supraglottis. A chest radiograph was normal.The patient was taken urgently to the operating room for direct microlaryngoscopy (Figure 1A and B) and intubated. Results of biopsies and cultures of the tonsils, adenoids, and supraglottis revealed diffuse non-necrotizing granulomas (Figure 1C) and oropharyngeal flora with negative acid-fast bacilli and Grocott methenamine silver stains. He remained intubated, and treatment with systemic corticosteroids and antibiotics was initiated. During this time, he had a normal angiotensin-converting enzyme (ACE) level and normal titers for antinuclear antibody (ANA), cytoplasmic antineutrophilic cytoplasmic antibody, perinuclear antineutrophilic cytoplasmic antibody, antimyeloperoxidase antibody, antiproteinase 3 antibody,anti-double-strandedDNAantibody,Smithantibody,Sjogrenantibodies,andhistoplasma antibodies. He also had normal results on tuberculin purified protein derivative and interferon-γ release assay (QuantiFERON; Qiagen).
