Neurofibromatosis type 1 with laryngeal involvement in an infant.

A 10-month-old female patient presented at the respiratory endoscopy service with inspiratory stridor, which she had suffered from the age of one month, impaired swallowing and increasing difficulty in breathing. A fibrolaryngoscopy was performed which showed a submucous mass which occupied the arytenoids and the left aryepiglottic fold and partially occluded the laryngeal lumen (Fig. 1A). Computerised tomography showed a 11.7 mm×5.8 mm lesion which was limited to the supraglottis (Fig. 2A and B). Physical examination revealed more than 6 ‘‘café au lait’’ spots on the skin, over 0.5 cm (Fig. 2C) in diameter. Neither cutaneous neurofibromas were present nor any family history of type 1 or 2 neurofibromatosis. Ophthalmology tested as normal, with no presence of Lisch nodules in the iris.
