Respiratory epithelial adenomatoid hamartoma of the maxillary sinus presenting as an antrochoanal polyp

الملخص EN

Respiratory epithelial adenomatoid hamartoma (REAH) is a rare benign upper airway lesion that is characterized by abnormal glandular proliferation.

Maxillary sinus localization is extremely rare.

Maxillary sinus involvement along with the extension beyond the sinus could be a challenge in differential diagnosis.

In this article, a case of an isolated maxillary sinus REAH extending to the choana is presented.
