Low-grade adenocarcinoma of the nasal cavity--an unusual presentation: case report and review of the literature.

Low-grade nasal cavity adenocarcinoma is an unusual neoplasm. When it does occur, it often appears in conjunction with a history of epistaxis and nasal obstruction that spans a period of a few weeks to several months. Most of these tumors arise in patients who are middle-aged or older. We report a case of low-grade nasal cavity adenocarcinoma that was unusual in that it occurred in an adolescent boy and that the presenting symptoms of chronic nasal obstruction and recurrent epistaxis had persisted for 7 years. The occurrence of this uncommon but recognized entity in such a young patient widens the age range of possible patients with this tumor, and a finding of such an extended duration of symptoms should raise clinical suspicion and encourage a thorough investigation in order to make the diagnosis.
