Mature Nasopharyngeal Teratoma in a Child.

Teratomas are neoplasms derived from the germ cell with components of all the three embryonic layers. These are rare neoplasms in head and neck region which can occur in any age group but are more prevalent in children. The present case is an 11-year-old girl who was brought with history of painless and progressive swelling in the oropharynx for 3 years with the associated left sided nasal blockage and nasal discharge. CT scan was suggestive of benign nasopharyngeal mass highly suspicious for lipoma. Excision of the mass was done under general anaesthesia. Peroperatively, it was a smooth, pedunculated mass arising from the left lateral wall in the nasopharynx. On cut section, it was solid to cystic mass similar to fatty tissue. Her HPE report came out to be mature teratoma of nasopharynx.
