title: Nasal chondromesenchymal hamartoma in an adolescent with pleuropulmonary blastoma.
abstract: Nasal chondromesenchymal hamartoma (NCMH) is an extremely rare benign lesion arising in the sino-nasal tract. They usually affect children below one year of age. The pathogenesis of these lesions is poorly understood however, they have been associated with pleuropulmonary blastoma (PPB). Although benign, malignant transformation has been reported in the literature. On literature review, we found 32 reported cases, most of them occurring in children below one year. We report a 14-year-old adolescent male with history of PPB at the age of 6, presenting with bilateral nasal obstruction and decreased sense of smell. In our case report we highlight the association between PPB and NCMH, and describe an unusual presentation.
