    Papiloma exofítico en la nasofaringe en un paciente de 5 años: reporte de caso y revisión de la literatura
    (2024) José Martes Fritz; Daniel Ruiz-Manco; Javier Ospina
    Upper airway (UA) obstruction in pediatric patients may rarely require ruling out less common entities such as nasopharyngeal masses. Case Report: Exophytic papilloma in a 5-year-old patient with a challenging clinical diagnosis. The clinical, radiographic, and therapeutic characteristics of this lesion are discussed through a review of the current literature. Discussion: Severe UA obstruction in pediatric patients warrants a thorough endoscopic and radiologic study. Nasopharyngeal tumors are an uncommon cause of UA obstruction in children. Exophytic papilloma is a benign tumor of the nasal cavity, originating from the Schneiderian mucosa. It is known for its high recurrence rate following subtotal resection. There have been only a few case reports when originating from the nasopharynx. Conclusion: Sinonasal papilloma is a low-incidence tumor in children, but it still must be considered a rare cause of UA obstruction. Therefore, patients must be properly approached in order to perform appropriate diagnostic and therapeutic management.
