Article information

We present a case of subglottic stenosis (SGS) in a young patient with positive ANCA but a wrong diagnosis of Wegener granulomatosis (WG). Instead, she was diagnosed as having laryngopharyngeal reflux (LPR). Pitfalls of ANCA testing in this scenario, the route to diagnosis of LPR and the contribution of this entity to subglottic stenosis (SGS) in WG are discussed. Caution when interpreting ANCA results is mandatory to avoid improper management.

Key words:
Wegener granulomatosis
Subglottic stenosis
Laryngopharyngeal reflux

Presentamos un caso de estenosis subglótica (ESG) en una paciente joven con ANCA positivos, pero un diagnóstico erróneo de granulomatosis de Wegener (GW). El caso correspondió a reflujo laringofaríngeo (RLF). Se discuten los falsos positivos de la prueba de ANCA, la ruta diagnóstica del RLF y la contribución de esta entidad a la ESG en GW. Debe tenerse precaución en la interpretación de ANCA para evitar el tratamiento inapropiado.

Palabras clave:
Granulomatosis de Wegener
Estenosis subglótica
Reflujo laringofaríngeo
