RESUMO
BACKGROUND: Laryngeal coccidioidomycosis is a rare but life-threatening manifestation of coccidioidomycosis. Data in children are sparse and limited to case reports. We conducted this study to review the characteristics of laryngeal coccidioidomycosis in children. METHODS: We performed a retrospective review of patients ≤21 years of age with laryngeal coccidioidomycosis who were treated from January 2010 to December 2017. We collected demographic data, clinical and laboratory studies and patient outcomes. RESULTS: Five cases of pediatric laryngeal coccidioidomycosis were reviewed. All children were Hispanic and 3 were female. The median age was 1.8 years and the median duration of symptoms before diagnosis was 24 days. The most common symptoms included fever (100%), stridor (60%), cough (100%) and vocal changes (40%). Airway obstruction requiring tracheostomy and/or intubation for airway management was present in 80%. The most frequent location of lesions was the subglottic area. Coccidioidomycosis complement fixation titers were frequently low and culture/histopathology of laryngeal tissue was necessary to make a definitive diagnosis. All patients required surgical debridement and were treated with antifungal agents. None of the patients had recurrence during the follow-up period. CONCLUSIONS: This study suggests that laryngeal coccidioidomycosis in children presents with refractory stridor or dysphonia and severe airway obstruction. Favorable outcomes can be achieved with a comprehensive diagnostic work-up and aggressive surgical and medical management. With the rise in cases of coccidioidomycosis, physicians should have a heightened awareness regarding the possibility of laryngeal coccidioidomycosis when encountering children who have visited or reside in endemic areas with stridor or dysphonia.
