Focal mucinosis of the upper aerodigestive tract in children.

ABSTRACT

Cutaneous mucinosis is an uncommon lesion characterized by mucin accumulation in the dermis. Rarely, mucinosis may arise in the oral cavity; reported cases have been observed in patients older than 16 years. We identified two children younger than 5 years of age with focal mucinosis of the upper aerodigestive tract. A 3-year-old boy had been intubated at age 2 months, suffered from recurrent respiratory infections, and developed mucinosis of the larynx, a previously unreported site for this unusual lesion. The second patient, a 4-year-old girl with a cleft palate, developed palatine mucinosis.
