Nasopharyngeal Hamartoma: A Case Report and Literature Review

Hamartoma is a non-neoplastic tumoral lesion resulting from a developmental anomaly and is characterized by the existence of cells and mature tissues common to the place of origin. Although hamartoma is common in the lung, kidney, and intestines, it is rare in the nasal cavity, the paranasal sinuses and particularly in the nasopharynx. Within the nasal cavity, the most common site of occurrence is the posterior aspect of the nasal septum. We reported a case of 15-year-old Thai male who presented with chronic rhinitis and left eustachian tube dysfunction for several months. Nasal telescopy revealed one smooth pink mass which originated from the left eustachian tube opening and another mass originated from the roof of the nasopharynx near the posterior part of nasal septum. Tumor removal was performed by endoscopic approach, and left myringotomy and a pressure equalization tube placement was done. No postoperative complications were found. Pathological diagnosis is consistent with hamartoma. After a 3 -month follow-up period, the patient still had a small residual mass in the left eustachian tube without any symptoms. Endoscopic approach enables the satisfactory role in the treatment of this rare condition
