title: Mesenchymal hamartoma in nasopharynx: a case report.
abstract: Hamartoma in the nasopharynx of the children is especially rare. Most documented cases occurred in infants, with characteristic histologic features of a mixture of various mesenchymal tissues. We report a case arising in a 15-year-old male patient, who presented with a 1-month history of right-sided nasal obstruction. The mass was resected endoscopically and confirmed histologically as a lymphoid hamartoma. We report and discuss the pathological features of this rare nasopharyngeal hamartoma.
