Disseminated Herpes Simplex Infection Presenting as Acute Supraglottitis in an Adult.

Supraglottitis is a life-threatening, predominantly bacterial disease that is rarely caused by viral etiologies. Herpes Simplex Virus (HSV) supraglottitis has been infrequently reported, but its presentation can mimic that of bacterial supraglottitis or pharyngitis which may lead to delayed diagnosis and increased morbidity. We present a case of supraglottitis in an immunocompetent man initially thought to have bacterial epiglottitis. After receiving a tracheostomy due to impending airway compromise and failing to improve on antibiotic therapy, biopsy of the upper airway tissue revealed infection with HSV type 2. The patient improved after multiple weeks of systemic antivirals. HSV supraglottitis remains an unusual but important diagnostic consideration in patients with dysphonia, dysphagia, ulcerative supraglottal lesions, and acute supraglottic inflammation unresponsive to antibiotics.
