RESUMEN
Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.
RESUMEN
Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman, RD) disease is a well known entity. This pathology is differentiated from other childhood histiocytosis with its distinct features. Many sites within the head and neck area may be involved with the disease. Multi-organ involvement is very rare. A patient with Rosai-Dorfman disease involving neck, nose and larynx is presented and clinical follow-up is given.
