Nasal chondromesenchymal hamartoma (NCMH) is an extremely rare benign pediatric tumor that was described in 1998. Only 19 cases are reported in the literature. We present a 15-year-old girl with nasal obstruction and recurrent sinusitis. Her medical history was significant for a rare ovarian tumor and pleuropulmonary blastoma. CT demonstrated a partially calcified soft-tissue mass obstructing the nasal cavity. The patient underwent endoscopic surgical excision. Histologic and immunohistochemical analyses of the tumor were consistent with NCMH. The imaging characteristics of the tumor are reviewed. NCMH may be part of a syndrome associated with other pediatric neoplastic and dysplastic disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
