Context: Osteoblastoma is a benign, slow-growing, but locally aggressive bone tumor. It is usually localized in the cervical vertebra but may rarely involve the laryngeal cartilage.
Case description: We report a case of osteoblastoma hypopharynx in a 10-year-old boy who presented with snoring and mouth breathing. His video laryngoscopic examination showed a mass in the pyriform fossa, which could not be excised by endoscopic excision technique and hence, was referred to our center for external approach excision. The whole mass was excised en bloc via an external approach, and a Ryles tube was inserted for 10 days. Histopathological examination (HPE) report came as Osteoblastoma. Ryles tube was removed after doing a fluoroscopy to confirm normal swallowing.
Conclusion: Osteoblastoma hypopharynx which has never been reported before in the literature can be treated completely by surgical excision via an open approach.
