Respiratory Epithelial Adenomatoid Hamartoma in a Young Female: A Diagnostic Dilemma

Hamartomas are non-neoplastic tissue abnormalities commonly found in various organs but rarely in the upper aerodigestive tract. Respiratory epithelial adenomatoid hamartoma (REAH) is a rare benign proliferation affecting the nasal cavity and sinonasal tract. It often mimics other nasal masses, leading to diagnostic challenges. We present the case of a 25-year-old female with recurrent epistaxis and chronic bilateral nasal obstruction. Diagnostic endoscopy revealed a polypoidal mass, later confirmed as REAH through histopathological examination. CT scans demonstrated soft tissue opacity but no erosion of surrounding bony structures. The patient underwent endoscopic excision, and the excised mass exhibited characteristic histological features of REAH. Endoscopic excision with careful postoperative follow-up can lead to successful outcomes in REAH cases. A year of follow-up revealed no recurrence.
