Sarcoidosis of the upper respiratory tract in children.

Sarcoidosis is a multisystemic granulomatosis of unknown etiology which mainly affects young adults. It is characterized primarily by bilateral hilar adenopathies, a pulmonary infiltrate and cutaneous and ocular lesions. It rarely occurs in children under the age of 16. Localization in the upper respiratory tract (URT) is infrequent and sarcoidosis of the URT in children is exceptional, with only 13 cases reported in the literature. In the present report we describe the clinical, diagnostic explorations, histological and therapeutic aspects of 2 new cases in children.
