Abstract
CASE DESCRIPTION: A 4-year-old horse was evaluated for chronic coughing, mucopurulent nasal discharge, and failure to thrive. CLINICAL FINDINGS: Endoscopy was performed on the larynx, pharynx, and trachea and revealed an approximately 2-cm fluctuant subepiglottic cyst. TREATMENT AND OUTCOME: The subepiglottic cyst was treated with intralesional formalin administration. Following 2 injections, 2 weeks apart, the cyst was completely resolved with no evidence of scarring or epiglottic deformity. CLINICAL RELEVANCE: Findings suggest that intralesional formalin administration for treatment of subepiglottic cysts may be a minimally invasive, economically suitable alternative to surgical treatments.
